Intraaortic balloon pumping assist following open heart surgery for coronary artery disease.
Intraaortic balloon pump (IABP) assist was employed in 36 patients after surgical operation for coronary artery disease. In 31 patients, the aid of IABP was required because cardiopulmonary bypass could not be terminated without it. In three of these patients, IABP assist was started before the surgical procedure because these patients were in cardiogenic shock due to myocardial infarction. In the remaining five patients, IABP assist was applied for refractory cardiogenic shock in the early postoperative period. The overall survival rate was 58 percent. IABP assist was used in 13 patients with an ejection fraction of 0.1 to 0.2 (normal 0.7). Nine of these patients survived. From our experience, it would appear that this temporary mechanical circulatory support provides a significant advantage in saving patients who might otherwise die after surgical procedures involving the coronary artery.
