Maureen O'Sullivan (1911)

Maureen O'Sullivan's acting career began when she met motion picture director Frank Borzage, who suggested that she take a screen test and then cast her in the film Song o' My Heart. She went on to appear in a number of movies for several studios before being chosen to play Tarzan's love interest, Jane Parker, in Tarzan the Ape Man and five other Tarzan features. In what other film did she play a character named Jane? More...

As Anna Quindlen wrote in Introduction for Pride and Prejudice, Jane is ``sugar to Elizabeth's lemonade.'' Jane is closest to Elizabeth, and her character is often contrasted with that of Elizabeth. She is favoured by her mother because of her beauty. Jane is considered the most beautiful young lady in the neighbourhood. O'Sullivan! Many happy returns of the day!

Probably heart attack was the sinister behind that heart surgery.
A heart attack occurs when one or more of the coronary arteries become blocked. The coronary artery bypass graft procedure is still the gold standard for patients suffering from left main or multiple coronary artery disease. The final determination that a coronary artery bypass graft operation is necessary is usually obtained from cardiac catheterization using coronary angiography. If the degree of blockage warrants surgery, a standard battery of tests (includes blood pressure (BP)) is performed before surgery. These tests can be done on an outpatient basis and typically include an electrocardiogram, routine blood work studies, chest x-rays, and urinalysis.

In addition, the blood is typed (found to be type A, B, AB, or O, for example) and cross-matched with donor blood. In some centers, the patient’s blood type is determined, but it is not cross-matched against a donor unit of blood in the hospital blood bank because there is about an 80 percent chance that a blood transfusion won’t be needed. By avoiding the cross-match, a certain amount of work and expense is avoided. If blood is needed, it can be crossmatched relatively quickly. In other centers, blood for transfusion is actually cross-matched and available. The crossmatching issue depends on the preference of the surgeon and surgical team.

The Choice of Conduits for Coronary Artery Bypass Grafting

During a bypass operation, the surgical team will need to “harvest” a vein or artery from elsewhere in the body to use as a graft. The most commonly used vein is the saphenous vein, which is taken from the leg. This is a superficial vein that runs from the groin to the ankle area and can be seen under the skin in many people when they stand up. It is one of the veins in the leg that may dilate over time and become varicose. In fact, not only is it a vein you can do without, but it can be a nuisance vein.

Although the saphenous vein is generally a good-quality blood vessel and can reach any coronary arteries, there is about a 3 percent to 4 percent chance per year that it will become narrow or totally blocked. Thus, the longterm patency rate (or chance of the vein staying open) is not as good as that of some other conduits.

Another very commonly used vessel is the left internal mammary artery, which is also called the internal thoracic artery. Using an internal mammary artery is a slightly different approach because one end of it is usually left connected to a branch of the aorta. There are two internal mammary arteries: One runs under the breastbone on the right side; the other runs on the left side. The left one can usually reach the left anterior descending coronary, which generally is the most important coronary artery for bypass. It also has an excellent patency rate — there is about a 90 percent chance it will be open twenty years later.

Sometimes its size is a disadvantage. It may only be a millimeter or less in diameter (there are about twenty-five millimeters in an inch), which is smaller than the coronary artery being bypassed, and sometimes the blood flow through it is inadequate. Occasionally, the internal mammary artery will not reach the point on the coronary that it needs to access. That obstacle can frequently be overcome by disconnecting the ``upstream” end and sewing one end to the coronary and one to the aorta or another artery.

The right internal mammary is also frequently used to bypass blockages in the coronary arteries. This artery usually reaches the right coronary, the left anterior descending and some branches of the circumflex. If it does not, the approach is generally the same. The upstream end of the artery is disconnected, and one end is sewn on the coronary artery and the other is attached to the aorta or to another bypass graft.

Another artery used for a bypass operation is the radial artery, which is located in the arm. Although some surgeons were using this artery for coronary bypass twenty-five years ago, recently it has become popular again. There is a single main artery in the upper arm called the brachial artery, which divides into two main branches near the elbow. One branch, the radial artery, runs along the inner forearm toward the thumb. The other branch, the ulnar artery, runs along the outer edge heading toward the little finger. These two arteries reconnect in the hand through an artery called the palmar arch artery. If the palmar arch is intact, it is possible to take a portion of the radial artery for a bypass graft. The reported results with radial arteries so far indicate that the vessel graft has a greater chance of staying open longer than saphenous vein grafts but not quite as long as the left internal mammary artery.

Doctors sometimes use an abdominal vessel called the gastroepiploic artery as the bypass graft. To use this artery, the abdomen must be opened. When using this artery, one end of it can be left attached to the stomach while the other end is threaded through a hole in the diaphragm, or breathing muscle, and joined to the appropriate coronary artery. The gastroepiploic artery can also be used as a free graft when both ends are disconnected. In this case, the other end is sewn to the aorta or another coronary bypass graft. The gastroepiploic artery graft seems to have a better patency rate than the saphenous vein graft but a somewhat poorer patency rate than the left internal mammary artery. The disadvantage of using this artery is that the surgeon has to make a second major incision to open the abdomen and devascularize (take part of the blood supply of) a portion of the stomach.

Over the years, doctors have found that using veins from the arms for coronary bypass grafting generally results in poor patency rates; therefore, in most cases, they are not used unless there is no other choice. In certain other cases, veins from a human cadaver have been used, but, again, the patency rates are not very good. This may be because of a rejection process that occurs from using tissue from another human. Synthetic arteries made of Dacron or other material have also been used. These grafts generally work quite well in other areas of the body, particularly in the larger arteries and the aorta, but the patency rates for coronary artery grafting have not been very good, and these synthetic arteries are not routinely used.

The Heart Operation

[W]e usually instruct our patients not to eat or drink anything after midnight the night before surgery. When they arrive at the hospital for surgery, patients generally report to the preoperative holding area, which is near the operating rooms. Some intravenous catheters are inserted through the skin, and a sedative is administered. At many heart centers, a local anesthetic is injected into the skin of the neck, and a larger catheter is introduced into the jugular vein and threaded through the right side of the heart into the pulmonary artery.

While the patient is still in preoperative holding, another catheter is placed in one of the arteries so that the arterial blood pressure can be monitored and blood samples can be drawn to check the arterial blood’s oxygenation level. This catheter is usually placed in one of the wrist arteries, often the radial artery. If a radial artery will be used for one of the bypasses, the other wrist can be used, or the catheter can be placed in the femoral artery by inserting it through the groin.

The patient is next moved into the operating room, and general anesthesia is induced.

Next, we place a plastic tube about as big as the index finger into the trachea. At some point, usually after the patient is anesthetized, a catheter is placed into the patient’s bladder. The patient’s chest and legs are swabbed with antiseptic soap solutions, and sterile operating drapes are placed on and around the patient. Now the team is ready to make the first incisions. Usually one surgical team will make one or more shallow incisions in the leg and harvest the vein for the bypass while the other team opens the chest.

To open the chest, an incision is made in the skin. The subcutaneous tissue is divided — that is a layer of fat usually a quarter- to a half-inch thick. In more obese people, however, it can be quite thick. Beneath that, a layer of muscle that is attached to the breastbone is cut through to expose the sternal bone. A saw is used to open the entire length of the sternum. Then a metal retractor is used to separate the sternal edges and hold the chest open.

With the chest open, we free up one or both internal mammary arteries and open the sac around the heart, or pericardium. A powerful anticoagulant, or blood thinner, called heparin is administered directly into the bloodstream to prevent the blood from clotting while the circulation is supported by the heart-lung machine. To hook a patient up to a heart-lung machine, stitches are placed so plastic tubes can connect the patient’s circulation to the machine. A tube about the size of the index finger is placed into the ascending aorta about three inches above where the aorta comes out of the heart. This tube delivers oxygenated blood from the heartlung machine to the patient.

Another catheter is placed through the right atrium. Some doctors use a two-stage cannula, with one part going through the right atrium into the inferior vena cava and a second drainage system remaining in the right atrium. In other patients, two separate venous catheters are inserted into these same areas. This depends on whether additional heart surgical procedures might be done and also on the preference of the surgeon. The tube or tubes in the right atrium return unoxygenated blood from the patient’s venous system to the heart-lung machine.

Frequently, an additional catheter is placed through the right atrium and manipulated into the coronary sinus. The coronary sinus is a vein that returns blood to the right atrium from the heart itself. This catheter is called a retrograde coronary perfusion catheter and is used to give part or all of the solution that will “turn off” the heart during the procedure.

After these catheters are in place, we will begin cardiopulmonary bypass by telling our technician or perfusionist running the heart-lung machine to turn on the machine with a command such as “on bypass.” The heart-lung machine then takes over the function of the heart and lungs. After it is activated, most surgeons will cool the patient’s body temperature to some level, but not all surgeons do this. There are advantages and disadvantages to cooling. The major advantage is that it adds an additional level of safety to the heart and the brain if some problem were to temporarily develop with the heart-lung machine.

After the patient’s circulation is supported by the heart-lung machine, most surgeons will “cross-clamp” the aorta by placing a clamp on the aorta between the heart and the catheter bringing oxygenated blood back from the heart-lung machine. This isolates the heart from the body’s main artery. At this point, most surgeons administer a solution called a cardioplegia solution {A solution that stops the heart from beating and reduces its oxygen consumption, thus allowing surgery to take place}, which stops the heart from beating. This is frequently injected into the coronaries through the aorta and also through the retrograde coronary sinus catheter into the veins of the heart.

This stops the heart and cuts down on the oxygen consumption of the heart muscle, as does the cooling of the heart. Once again, not all surgeons use these techniques, but the vast majority do...

With the heart stopped and the body supported by the heart-lung machine, the coronary arteries that are to be bypassed are identified. We usually have a mental picture of exactly where we want to put the bypasses and know where the blockages are. Frequently, the last thing we should do before scrubbing in, gowning up, and putting on sterile gloves is look again at the movies of the patient’s coronary arteries. The images are individual frames from xrays, which, when shown sequentially at high speed, look like a movie of blood flowing through these arteries. During surgery, most surgeons wear powerful magnifying glasses that increase the size of the relatively small coronary arteries at least two to four times. Some surgeons use a special type of microscope that magnifies the arteries even more.

[W]e next isolate the obstructed coronaries, which tend to be on the surface of the heart. Sometimes they are hidden in a layer of fat on the heart and have to be located. Other times they’re in the heart muscle. The coronary arteries are opened beyond the obstruction and measured. The internal diameters tend to be in the range of from one millimeter to two millimeters, which is about the size of a straw from a broom.

Placing the Graft

With the coronary opened beyond the area of obstruction, we are ready to place the bypass graft. To do this, we join one end of the vessel conduit to the coronary artery with small stitches usually made out of polypropylene. The needle itself is joined to the stitch, and if you hold the needle and suture in your hand, you may have to squint to see them because they are so small. After all the bypasses, which can range from one up to eight or nine grafts (but typically three or four), are sewn to the coronaries, the other ends are joined to the aorta or, in some cases, to other veins or arteries. If I've decided to use an internal mammary artery, one end is already connected to the arterial system.

The bypasses are now complete, and any air that might have gotten into the heart is removed, and the patient’s body is rewarmed. The heart usually restarts on its own but sometimes needs the help of a temporary pacemaker or an electrical shock. It might have to be paced a while with a temporary pacemaker until its natural rhythm kicks in. Temporary pacing wires are usually connected to the heart and can be removed a few days after the surgery by pulling them out. Some surgeons choose to leave them in, cut them off at the skin level, and let them retract.

After the heart has started, our patient is weaned from the heart-lung machine by slowly turning the heart-lung machine off as the patient’s own heart and lungs take over. In some cases, the heart is too weak to take over for whatever reason, and another attempt or two will be made at letting the heart take over. If these are unsuccessful, we may use an intra-aortic balloon pump, which is a pump that is threaded through an artery, usually through the groin, and connected to an external power source. There is a balloon on the tip of a long, thin tube that inflates and deflates in synchrony with the heart, helping the heart to pump blood as the patient gets through the early postoperative period.

In more severe cases when the heart does not take over, some form of ventricular assist device may have to be used. This is relatively uncommon. Most patients are weaned from bypass without the use of any type of mechanical support on the first attempt.

After we check the operative field to make sure that all bleeding has stopped, drainage tubes will be placed, and the sternum will be closed, usually with stainless steel wires that are left in permanently. The layers of the tissue are sewn together, and the skin on both the chest and the leg wound may be closed with sutures or metal staples. When stainless steel staples are used to close the skin, they are usually removed a week or two later, although the timing of the removal is the surgeon’s preference and may depend on other pre-existing medical conditions.

The Postoperative Intensive Care Unit

Patients are not yet awake when they leave the operating room and are transferred to an intensive care unit. A portable monitoring system usually accompanies patients so the surgical team, while in transit, can continually read the electrocardiogram and the arterial blood pressure. After the patient arrives in the intensive care unit, various monitoring lines including an ECG are connected, and the patient slowly wakes up over the next hour or so. Today, we tend to remove the breathing tube from most patients within the first several hours after the heart surgery. Sometimes, if the patient’s breathing has not taken over sufficiently, it may be left in a little longer.

Most patients stay in the intensive care unit overnight and are discharged from intensive care to the step-down unit the next day. Being transferred from the intensive care unit to a step-down unit depends on a few factors. The patient must not need the ventilator. It might also depend on how well the heart and lungs are working, and sometimes it is also related to the surgical team’s preference. When the patient gets to the stepdown unit (also referred to as the ``floor’’ or ``ward’’), he is already drinking liquids and sometimes eating semisolid food.

Within a day or two, the diet will rapidly progress to regular food. Patients also often walk up and down hallways, with some assistance, after a day or two on the ward. Discharge from the hospital can be as early as three days after the surgery but is usually about four days to a week after heart surgery, although this can be extended for various reasons.

Interestingly, although everybody’s pain threshold is different, the midline incision through the breastbone is not very painful. Most patients are sent home with only a mild pain medicine. With routine coronary bypass operations, the chances of surviving the heart operation and walking out of the hospital are better than 99 percent.

Factors that can increase the risk of the surgery include the relative health of the left ventricle. If it’s fairly normal, the risk of the surgery can be very low. If it’s badly damaged from previous heart attacks, the risk could be greatly increased. Patients who are in the middle of having a major heart attack and/or in cardiogenic shock during the surgery are at increased risk. Other risk factors include lung disease and other important medical conditions, previous strokes, obesity, and additional heart surgery, like valve replacement, during coronary bypass surgery. Risk is also increased in patients who have had previous heart surgery and in the elderly, particularly in those more than eighty years old.

Minimally Invasive Direct Coronary Artery Bypass (MIDCAB) Surgery

As medicine and surgery advance, newer techniques are constantly being developed. MIDCAB procedures are coronary artery bypass operations done without the aid of a heart-lung machine and that use novel devices and techniques. Coronary bypass surgery has been performed by some surgeons without the use of the heart-lung machine since the beginning, but the vast majority have used, and still use, the heart-lung machine.

New technology, however, has prompted many heart surgeons to take a long, hard look at performing coronary bypass grafts in selected patients without the use of the heart-lung machine. Some surgeons now are performing surgery, particularly when only one or two bypasses are needed, through a small incision in either the left or right side of the chest, depending on where the bypass graft is to be placed. This is done without the use of the heart-lung machine. There are certain advantages to performing the surgery without the aid of the heart-lung machine, yet there are many advantages to performing heart surgery with the heart-lung machine.

Nonetheless, these techniques are being evaluated at many centers around the world. If everything goes well and the heartlung machine is not used, you can have the breathing tube removed sooner after the surgery and may be able to go home a day or two earlier. Some of the surgeons doing the surgery without a heartlung machine have used videoscopes with remote TV cameras to perform portions of the operation, such as freeing up the internal mammary artery. Some have used videoscopes with special instruments to join the coronary artery to the internal mammary artery. Some surgeons use the routine midline incision through the breastbone but then perform the coronary bypass procedure without the heart-lung machine.

Again, there are advantages and disadvantages to doing this. Not all patients undergoing heart surgery at this time are eligible for these MIDCAB procedures. At one center in California, where the surgeons are prepared to do this in any eligible patient, they have found that over the last three years about 6 percent of the coronary bypass surgeries have been done without the use of the heart-lung machine. In another center in New York that is well known for this type of coronary bypass surgery and has had a lot of self-referrals especially for this type of surgery, the percentage of cases done without the use of the heart-lung machine is about 16 percent of the total number of patients undergoing coronary bypass grafting...

Although the initial results with MIDCAB surgery have been positive, it is probably too early to tell whether the number of MIDCAB operations will continue to grow. After surgeons gain more experience, some may decide to go back to doing most or all of their cases with the aid of the heart-lung machine. Time will tell whether these efforts are worthwhile.

Complications from Coronary Bypass Surgery

There are complications that can occur during even ``routine” coronary bypass surgery. A patient can have a heart attack during or shortly after the heart operation. It might be related to one of the bypass grafts clotting up or possibly to other events related to the heart surgery. The heart may fail even without a heart attack, requiring an intra-aortic balloon pump or mechanical assist device to be placed.

A patient may develop respiratory insufficiency [When the lungs are not functioning normally] or pneumonia and require prolonged stays including treatment with a respirator. Kidney failure may develop. This is more likely in people who have some degree of pre-existing kidney failure and in those with low cardiac output for prolonged periods. Wound infections are another risk with any major surgery.

Fortunately, most patients undergoing coronary bypass surgery are at a very small risk, only a few percent, for any serious complications. Less serious side effects are not so rare, however, and can range from the annoying to something that needs to be fixed with surgery. One of these is excessive blood loss from the chest drainage tubes, which can happen for a variety of reasons. To stop the blood loss, the patient has to be taken back to the operating room. This happens about 2 percent to 4 percent of the time.

Heart arrhythmias, or irregular heartbeats, are fairly common after heart surgery. Most are not serious and are more of a nuisance than anything else. About 20 percent to 30 percent of our patients develop atrial arrhythmias, sometimes atrial fibrillation or atrial flutter. Also, the ventricles may beat faster than normal. Again, these are usually not serious conditions but just require treatment with medicines. Sometimes, the heart even has to be shocked electrically back into a normal rhythm. The likelihood of these irregular rhythms decreases in the first few days after the surgery, and, by about a month after the surgery, most additional medicines prescribed to treat these abnormal heart rhythms can be discontinued.

Strokes during or after Coronary Artery Bypass Surgery

Patients may suffer a stroke during or shortly after heart surgery. The chances are about 1 percent in a person who has never had a stroke before but can be as high as 5 percent or 10 percent in patients who have had a previous stroke. Sometimes strokes can be very severe. The patient may be in a coma and never wake up after the surgery.

Fortunately, most strokes are much less severe, and most patients who have a problem with their speech or a weakness in an arm or a leg either totally recover or recover to some degree. One of the causes of strokes is related to blockages in the arteries that deliver the oxygenated blood to the brain. The two major arteries are called the carotid arteries, and they can develop atherosclerotic disease just as the coronaries can.

When both the coronary artery and the carotid artery blockages are severe, the surgeon will most likely treat both problems at the same time. On the other hand, if one of the two problems is less severe, surgeons tend to first operate on whichever problem is more severe. The preference for which operation to do first or whether to do both at the same time varies with surgeons, and there is a certain amount of information to support one approach versus the other in specific situations.


From a surgical standpoint, the only medicine that we routinely recommend is an aspirin a day. Some physicians choose a baby aspirin, and others choose a regular aspirin. Aspirin probably helps keep the coronary bypass grafts open longer, but that has not been proven conclusively. Because aspirin is relatively benign, however, it's worth the effort.

When the patient is discharged from the hospital, the biggest restriction is that the patient should not lift anything heavier than about twenty pounds for the first couple of months while the breastbone is healing. After three months, the patient can generally resume vigorous activity. That could even mean playing professional sports such as ice hockey or other strenuous contact sports. Before attempting any type of vigorous activity after heart surgery, however, you must first clear it with your cardiologist.

Although patients gain confidence while walking around the hospital ward, once they return home, our patients often realize they’re weaker than they think they are. However, they are usually still able to go outside for brief walks. Within a month, most patients are able to walk a mile or two. If the weather is bad or un--usually cold, patients often choose to walk inside a shopping mall. Some cardiologists prefer to enroll all of their patients in cardiac rehabilitation programs, whereas others only enroll some, particularly those who get little exercise.

The Postoperative Exercise Stress Test

Three weeks to two months after the surgery, the cardiologist may prescribe an exercise stress test. Some cardiologists order an exercise stress test for all of their patients who have recently undergone coronary artery bypass surgery, whereas other cardiologists are more selective. These cardiologists do stress testing of patients with unusual symptoms, those who are going to do vigorous exercise such as jogging and playing tennis, or people who have jobs that require extra caution, such as commercial airline pilots. If the exercise test result is normal, most cardiologists allow the patient to go back to any type of normal vigorous activity.

Common Postoperative Complaints

I hear several common complaints when we see patients four or five weeks after coronary bypass surgery. One is poor appetite. In virtually all patients, this improves anywhere from three weeks to two months after the surgery, and in most cases, they will regain weight to their presurgery level. If, on the other hand, they are overweight, they may prefer not to get back to that level, and diet counseling is normally done not only in the hospital but by the patient’s own cardiologist. This also applies to special diets recommended by a cardiologist.

Another complaint we frequently hear three to five weeks after the surgery is trouble sleeping. I’m not sure why many of my patients have unusual problems with not being able to sleep. It may be that during heart surgery or time in the intensive care unit, the clock in the patient’s brain, or circadian rhythm, gets reset, and it may take awhile to revert to a normal routine. Most patients return to their normal sleep patterns five to seven weeks after surgery.

Our patients sometimes complain about night sweats. This problem usually resolves itself, although occasionally night sweats can indicate a serious problem, particularly if they are associated with high fevers. In most patients, however, it is a side effect that seems to be unique to either the heart surgery or a major operation. The condition gets better in a month or two.

Numbness is another complaint, particularly if it is located in the left chest area or left breast in women. It seems to be more common in patients in whom the left internal mammary artery was used for a bypass graft. Some patients notice some numbness along the vein harvest site in the leg, particularly around the ankle area. This can be related to damage to the small branches of the nerve that intertwine with the saphenous vein. These problems usually subside over a couple of months. Some patients have numbness or tingling in their little finger and the finger or two next to it, either in one or both hands. This common complaint is thought to be related to the fact that when the chest retractor is opened, it stretches the ulnar nerve as it comes out of the spinal cord, loops over the first rib, and goes into the arm. This problem, when it occurs, almost always subsides, sometimes taking five or six weeks or longer.

Occasionally, patients say their eyeglasses are a bit out of focus. This seems to be a problem that is not specific to heart surgery but occurs following all types of major surgery. I am unclear why this occurs, but ophthalmologists usually say patients should wait a couple of months after a major operation before getting their eyeglass prescriptions changed because their visual acuity tends to return to what it was before the surgery.

Over the years, we have also noticed patients may come in for their heart surgery taking a certain antihypertensive (blood pressure) medication, and go home taking less of that medicine or none. A month later, however, they need the medicine again and don’t know why they were not sent home taking it. While patients are in the hospital, particularly while in bed for two to four days, the tone in their blood vessels tends to relax somewhat. When they are up and around again, the tone may not return as quickly, and their blood pressure may be a little lower than it was before the heart surgery. This explains why they may not need the antihypertensive medicines they previously took. However, after about a month or six weeks, when the blood vessel tone returns, they often need to take the same blood pressure medication they took before the surgery.

Patients with diabetes often go home with different insulin requirements than they had before the heart surgery. Sometimes diabetic patients who were not taking insulin go home taking insulin, and sometimes those that are taking insulin, particularly lower doses, will go home and not need insulin. In general, we find that after five to seven weeks, patients tend to require whatever dose of oral antihyperglycemics or insulin they had been taking before the heart surgery.

Our patients frequently tell us that when they lie on their side, particularly their left side, they notice their heart beating more than they did preoperatively, and they think perhaps this is dangerous. This is a common complaint and is generally caused by adhesions that have formed around the heart in the healing process. They are feeling the tug of these adhesions as the heart beats. Over time, however, the adhesions stretch, and most patients become used to it and no longer notice it.

Some patients notice a lump at the top of their breastbone that wasn’t there before the surgery. If the lump is red and tender, it could signal an infection, but usually the lump appears because there is a layer of fat under the skin that does not hold stitches too well, and the consistency of that fat is somewhat like cottage cheese. To get stitches to hold, we have to place them deeper into the tissue, which tends to wad the tissue up around the stitch. Also, we place deeper stitches because the skin along the middle of the breastbone tends to pull away toward the arms. Over time, the lump will usually even out and return to normal.


Fortunately, over the last ten years, we have seen a decrease in the death rate from coronary artery disease in the United States. This is probably due to a number of factors, including better education of the general public, particularly about diet, cigarette smoking, and, in some cases, changes in life style.

This decrease is probably also due to relentless campaigns by the American Heart Association, the National Institutes of Health, and other groups, including national medical and surgical societies that deal with heart disease. They not only educate the public but also fund research in these areas. We also have better medications, and, certainly, the invasive cardiology field has come a long way, including the use of balloon dilatation and stents to treat various forms of blockages in the coronary arteries. Despite all of this, it appears that coronary artery bypass graft surgery will be around for the foreseeable future and continue to play a major role in the treatment of patients with advanced forms of coronary artery disease.
