Abstract
- Treatment of total left main coronary artery occlusion is rarely reported (84 chronic and acute cases in the world literature), due to the high mortality rate from massive myocardial infarction. Acute occlusions have been treated with intracoronary streptokinase, with percutaneous transluminal coronary angioplasty, or with both. To date, there has been no report of successful surgical revascularization in an acute case. We present 2 cases of surgically treated patients who survived total left main coronary artery occlusion that appears to have been acute, or acutely evolving. Both patients had an 80% or greater stenosis of the right coronary artery, yet have remained in New York Heart Association functional class I or II postoperatively. We attribute this not only to the aggressive surgical approach, which enabled reperfusion to be achieved within 2 hours of total occlusion, but to the protective effect in these patients of right coronary-to-left anterior descending collaterals.
