Total arterial revascularization of the heart using both mammary arteries and the right gastroepiploic artery.
From April 1988 to April 1989, nine patients (seven men and two women) with coronary three-vessel disease and disabling angina underwent elective myocardial revascularization. None of the patients had available veins because of previous bypass procedures (three) or extensive varicosis (six). On standard cardiopulmonary bypass and cardioplegic arrest the right and the left mammary arteries (RIMA, LIMA) and the right gastroepiploic artery (RGEA) were anastomosed each to a major coronary branch (none of them as free graft) in each patient. All patients survived the operation but one, who died 2 weeks after the operation of a bilateral pneumonia. Autopsy revealed patent anastomoses. One patient had to be reexplored for bleeding. Two patients required temporary inotropic support. There was no perioperative myocardial infarction. All survivors were discharged home in an average of 18.7 days after the operation, are free from angina, and all have negative stress tests (mean follow-up 7.7 months) but one with severe coronary atherosclerosis who experiences slight exertional angina despite good patency of the grafts. Five patients were recatheterized after a mean interval of 5.4 months after operation revealing in all cases patent anastomoses. Total revascularization of the heart with arterial grafts is feasible, safe, and it could become the method of choice if patency persists in the long run.
