Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial infarction (MI). A 66-year-old Japanese man, who had had an anterior wall MI caused by SCAD of the left anterior descending coronary artery, developed left ventricular aneurysm 5 years later, with depressed left ventricular function and thrombus observed on echocardiography. Left endoventricular circular patch plasty according to Dor's technique was performed without coronary artery bypass grafting, because of the absense of significant coronary artery stenosis on the preoperative coronary angiogram. The clinical course of SCAD in the late phase is generally favorable, but because the prognosis of SCAD is uncertain, patients with SCAD should be carefully followed. (Circ J 2002; 66: 972 - 973)
