Iatrogenic Acute Aortic Dissection during Percutaneous Coronary Intervention for Acute Myocardial Infarction.

Iatrogenic acute aortic dissection during percutaneous coronary intervention is an extremely rare, but critical complication. Localized aortic dissections have been treated by sealing the entry with a coronary stent. Extensive dissections may require a surgical intervention. We present a case of type A extensive aortic dissection occurring during angioplasty of the left circumflex artery for acute myocardial infarction. This iatrogenic aortic dissection required emergent surgical repair with supracoronary replacement of the ascending aorta.
