ALCAPA in adulthood: A CT perspective

Abstract

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital abnormality of the coronary arteries. It typically presents with acute, non-exertional left-sided chest pain, accompanied by sweating and palpitations, often in the presence of a significant medical history. The condition is commonly diagnosed through advanced imaging techniques, such as CT coronary angiography or cardiac MRI, which provide detailed views of the origin and path of the abnormal coronary artery. Early identification and timely surgical intervention aimed at restoring normal coronary circulation generally lead to excellent outcomes, with gradual recovery of the heart muscle. This case report discusses a late presentation of ALCAPA syndrome.
