Abstract

Anomalous left coronary artery arising from the noncoronary cusp (LCANCC) is a rare congenital disorder. We herein describe a 17-year-old female patient with sudden cardiac arrest followed by refractory cardiogenic shock. LCANCC-induced acute myocardial infarction with left main coronary artery involvement was subsequently diagnosed, and the patient required a durable left ventricular assist device. <Learning objective: Anomalous left coronary artery arising from the noncoronary cusp is extremely rare, but poses a life-threatening condition. Coronary computed tomography angiography plays a crucial role for the assessment of high-risk anatomic features and decision-making for surgical repair.>.
