Myocardial perfusion, scarring, and function in anomalous left coronary artery from the pulmonary artery syndrome: a long-term analysis using magnetic resonance imaging.

Background: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect. We aimed to examine the role of cardiac magnetic resonance imaging (MRI) in the long-term surveillance of repaired ALCAPA with regard to myocardial scarring, wall motion abnormalities, perfusion deficits, and myocardial function.

Methods: Twenty-one patients after direct reimplantation of ALCAPA (median age at operation, 2.
