Anomalous right coronary artery from the pulmonary artery: noninvasive diagnosis and serial evaluation.

Isolated anomalous origin of the right coronary artery from the main pulmonary artery (ARCAPA) is a rare congenital cardiac malformation. We reviewed the current literature and found only 31 patients with ARCAPA. We report the first case that was diagnosed and followed on a noninvasive basis with cardiovascular magnetic resonance after surgical re-implantation. This report of a patient with ARCAPA showed resolving coronary artery sizes secondary to decreased pulmonary steal. Cardiovascular magnetic resonance is an accurate and reliable imaging modality that allows serial noninvasive follow up in patients with coronary artery anomalies.
