    Abstract:
    From January, 1984 to May, 1990 eleven patients (men 9, women 2) underwent coronary artery bypass surgery for chronic total occlusion of the left main coronary artery by means of intermittent antegrade cold blood cardioplegia. The ages ranged from 33 to 74 (mean 56) years. The causes of the total occlusion of the left main coronary artery were atherosclerosis in 10 patients and aortitis syndrome in one. Four patients had history of a previous myocardial infarction. Preoperative selective coronary arteriography revealed well developed collateral vessels from the RCA to the LCA in all patients. One to five coronary arteries were bypassed. Myocardial protection was obtained in the usual fashion: antegrade intermittent cold blood cardioplegia with topical cardiac cooling. All patients were successfully weaned off from cardiopulmonary bypass without the need of IABP assist. No patient developed perioperative myocardial infarction. All grafts were patent postoperatively. Treadmill testing was negative in all patients. We believe that coronary artery bypass surgery for chronic total occlusion of the left main coronary artery can be performed safely with intermittent antegrade cold blood cardioplegia.
