In beating-heart surgeries currently used in about 22 percent of US bypass procedures a surgeons ability to stitch vessels onto a moving, blood-filled heart replaces the need for the heart-lung machine. A stabilizer, a small device with a suction cup attached, is used to minimize the motion of the heart where the stitching is done. The hesitancy of most surgeons to switch to beating-heart surgery is, in part, due to the overall success of the heart-lung machine over the past 40 years. In other words, if it aint broke, why fix it? But proponents of beating-heart surgery, point to the risks associated with conventional bypass surgery, including blood loss, stroke and kidney failure. Because the body doesnt have the added stress of being put on a heart-lung machine, beating-heart surgery can reduce these risks, and does so particularly well among such high-risk groups as the elderly and, surprisingly women. For reasons, nor well-understood, women dont do as well during bypass as men. Women have double the mortality rates following bypass. Besides his own positive experiences with the technique, points to a recent report in the new journal Innovations which presents an analysis by an international group of doctors of more than 150 previous studies of the procedure. It found that the beating-heart technique is as safe as conventional heart surgery, with fewer complications and lower costs. The consensus report, based on randomized controlled trials and retrospective studies, concluded that when complications such as blood loss, stroke, kidney failure and irregular heart beats were considered, beating-heart surgery had a definite advantage over conventional bypass.
Beating-heart surgery is an advance in cardiac surgery because it provides a better result for patients. Still, scientific evidence does not yet conclusively show its benefits, adding that he wants to see more research done before hes convinced. Its just so difficult when it was developed a decade ago and now uses it only occasionally. We dont have the time to devote to it. You need to do it often to be good at it. Which is exactly what they plan to do, they completed more than 130 of the surgeries and do their bypass work off-pump. They really want to build an off-pump center before scrubbing up for surgery on that afternoon earlier this year. They want patients sent there from everywhere. They would spend the next three-and-a-half hours intricately stitching new blood vessels onto the beating heart of his patient. When he lifted the heart out of the chest, a tricky step in the beating-heart procedure, the doctors and nurses and technologists in the room turned suddenly quiet. The beat, beat, beat of the heart monitor filled the air. Surgeon found the spot he was searching for on the hearts backside and, finally, looked up. Everything is okay really stable, patients tolerating it really, really well.
