Coronary artery endarterectomy: a method of myocardial preservation

Tex Med. 1993 Jun;89(6):56-9.

Abstract

The lack of acceptable coronary arteries for grafting often causes the cardiac surgeon considerable problems in treating patients with severe coronary artery disease. By combining the standard approach of coronary bypass surgery with coronary endarterectomy and with retrograde coronary sinus cardioplegia perfusion, we can achieve a longer ischemic period and can flush the debris from the coronary arteries in a retrograde fashion. Using this approach, we managed 72 patients with near inoperable coronary artery disease. One third of these patients required endarterectomy of more than one vessel. A higher than expected number of patients had diabetes mellitus. The left coronary artery system required endarterectomy in almost 60% of patients, much higher than percentages reported in other series of patients. The mortality rate in our patients who underwent the left system endarterectomy was 5.7%. Endarterectomy must be considered an adjunct in the management of high-risk patients with severe coronary artery disease.
