Succesful treatment of spontaneous dissection of the coronary artery by primary percutaneous coronary intervention

摘要

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction. The disease is usu-ally seen in young-middle aged women and leads to sud-den death in the majority of cases. In survived patients, diagnosis of SCAD has been made with coronary anjiog-raphy. Involvement of left main coronary artery (LMCA) is very unusual. We describe on a case of SCAD involving the LMCA in a young woman presenting with an acute myocardial infarction and cardiogenic shock status. There were no risk factors for coronary artery disease and no evidence of atherosclerosis on angiography. Coronary an-giography revealed dissection of the LMCA that extended into the anterior descending and circumflex coronary ar-teries. The dissection was successfully treated with prima-ry coronary artery stenting. The patient was discharged without complication. There was no problem in the first evaluation at the end of the first of the month
