An unusual cause of acute coronary syndrome: Left ventricular outflow tract pseudoaneurysm

Left ventricular outflow tract (LVOT) pseudoaneurysm is an uncommon but life-threatening pathology. It is generally observed after cardiovascular surgery or infective endocarditis. Its course ranges from an asymptomatic situation to severe complications including rupture, thromboembolism, fistula formation, and compression to the surrounding tissue (1-4). LVOT pseudoaneurysm usually presents with non-specific symptoms including chest pain, dyspnea, and cough. Until now, few cases with stable angina pectoris caused by LVOT compression on the left coronary arteries have been reported. However, in this case report, we present a patient with non-ST-elevation acute coronary syndrome caused by LVOT pseudoaneurysm
