[Coronary malperfusion of left main trunk due to localized dissection of the ascending aorta].
Case 1. Forty nine years woman was given a diagnosis of acute myocardial infarction. Coronary angiography and trans-esophageal echocardiography showed left main trunk dissection due to local aortic root dissection. We operated surgical repair at left main trunk by pericardium after percutaneous coronary intervention. Case 2. Forty nine years man was given a diagnosis of acute myocardial infarction caused by left main trunk dissection due to traumatic local aortic root dissection. We operated coronary artery bypass grafting after insertion of perfusion catheter to left main trunk for maintain coronary perfusion. Although local dissection of aortic aorta is relatively rare, it is potentially complicated with coronary malperfusion. We describe 2 success a cases of surgical treatment for local acute type A aortic dissection complicated with coronary malperfusion.
