An anomalous left coronary artery from the pulmonary artery(Bland-White-Garland syndrome) is a rare congenital malformation and sometimes fatal. It is caused by an abberant endothelial budding from or an anomalous division of the truncus arteriosus. Echocardiography (transthoracic and transesophageal) and angiographical imaging are essential for the diagnosis of this anomaly. Corrective Surgery is recommended due to its fatal natural course. A case was diagnosed in a 45-year-old man who presented with intermittent palpitation. This patient was successfully treated with closure of anomalous left coronary artery orifice combined with right saphenous vein graft anastomosis.
