Abstract

A 37-year-old woman presented with occasional chest pain on exertion. Physical examination and ECG were normal. Transthoracic echocardiography demonstrated dilated, tortuous coronary arteries, and the right coronary artery (RCA) origin could not be identified. The patient was then referred for coronary CT angiography (CTA).
