Left main coronary artery dissection during percutaneous transluminal coronary angioplasty.
Acute dissection of the left main coronary artery during diagnostic cardiac catheterization with selective coronary arteriography is an uncommon but recognized complication of the procedure. That similar dissection may occur during percutaneous transluminal coronary angioplasty is less well recognized. This report describes two cases of left main coronary dissection resulting in acute occlusion that occurred during percutaneous transluminal coronary angioplasty and demonstrates that survival with essentially complete functional recovery may result if immediate surgical intervention is undertaken. Recognition and treatment of this potentially catastrophic complication of angioplasty is described.
