Conventional heart bypass surgery is performed on a stopped heart through a 10″-12″ incision down the middle of the chest”. Patients are placed on cardiopulmonary bypass (CPB), or a heart-lung machine. The heart-lung machine functions as the patient’s heart and lungs during the operation.
What are the risks associated with conventional heart bypass surgery?
Many surgeons consider the heart-lung machine to be the most “invasive” component of conventional bypass surgery. Patients who are placed on the heart-lung machine are more likely to experience complications after surgery than patients who have beating-heart bypass surgery. Complications of the heart-lung machine can include stroke, seizures, multiple organ dysfunction, and compromised immunity. Frequently, patients who have conventional bypass surgery also require more blood transfusions and longer hospital stays.
