Within a 2.5-year period between 1985 and 1988, long coronary arteriotomy, endarterectomy and reconstruction (principally left anterior descending artery) and multiple bypass grafting (mean graft rate was 9) were performed in 130 of 329 patients (40%) with severe diffuse coronary artery disease to ensure complete myocardial revascularization. Ninety-two percent of the patients who underwent exercise testing had abnormal (greater than 1 mm ST) depression and/or positive results on scintigraphy. Long coronary arteriotomy (5 to 12 cm), endarterectomy and reconstruction of the left anterior descending artery and its branches, were performed in 121 patients; of the left circumflex artery and its branches in 13 patients; and of the right coronary artery and its branches beyond the crux in 18 patients. Single endarterectomy and reconstruction was performed in 109 patients, double in 20 and triple in 1. The operative mortality was 2.3% and the perioperative infarction was 1.5%. Twenty-four patients (among them 38% who had undergone greater than 1 previous bypass operation) were randomly selected and studied within 20 days after surgery. This group comprised a total of 69 coronary conduits of which 68 (99%) were patent, and a total of 206 coronary anastomoses of which 202 (98%) were patent. Thirty-two of 33 conduits (97%) to endarterectomized and reconstructed arteries were patent. One hundred and twenty-six of 127 patients were followed up for a mean of 20 months; 120 of the 121 patients (99%) were in angina class I by Canadian Cardiovascular Society classification, and 63 of 71 patients (89%) had a normal treadmill exercise stress test.(ABSTRACT TRUNCATED AT 250 WORDS)
