|
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly associated with very high mortality during infancy. We report a 35-year-old female patient with ALCAPA initially visualized by echocardiography. She visited outpatient department presenting with intermittent chest discomfort for 3 weeks. Transthoracic echocardiography showed left coronary artery arising from main pulmonary artery and abundant septal color flow Doppler signals. Transesophageal echocardiography clearly revealed markedly dilated and tortuous right coronary artery showing windsock appearance. Multidetector computed tomography and coronary angiography enabled visualization of anomalous left coronary artery originating from left side of main pulmonary trunk. After treadmill exercise test which showed ST-segment depression presenting inducible myocardial ischemia, patient underwent direct re-implantation of the anomalous coronary artery into the aorta without any complication.
