Type A aortic dissection after percutaneous coronary intervention is a rare and life-threatening situation. The reported incidence ranges from 0,02% to 0,6% of all diagnostic and interventional percutaneous procedures. We describe a case of aortic dissection after percutaneous coronary intervention in a patient with acute myocardial infarction from spontaneous coronary artery dissection. The patient was initially treated with primary percutaneous coronary intervention of the affected left coronary artery branches and left main coronary artery. Conservative management for the aortic dissection proved inadequate due to increasing diameter of the false lumen and the patient was referred to our cardiovascular unit for definite surgical management.
