A woman in her 60 s presented with chest pain. The electrocardiography showed ST depressed in V3-V6, ST elevation in aVR, and negative T in I, II, aVL, and aVF. Laboratory examination revealed that creatinine kinase isoenzyme-MB and troponin I were elevated. Transthoracic echocardiography revealed moderate aortic regurgitation. Enhanced computed tomography did not show an aortic dissection. Acute coronary syndrome was suspected and cardiac catheterization was done. Aortography showed an intimal flap inside the Valsalva sinus. An emergency operation was performed. Surgical view: the intimal tear affected almost all the circumference of the aorta in the Valsalva sinus and the aortic dissection with a localized and moving intimal flap affected the coronary flow and the aortic dissection caused severe aortic regurgitation and decreased the coronary flow. An aortic root replacement was successfully performed, and the postoperative course was uneventful.
