Abstract
Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a very rare congenital heart defect. Most patients are asymptomatic and the anomaly is detected incidentally during evaluation for other problems. Occasionally, ARCAPA may lead to myocardial ischemia and/or sudden cardiac arrest. Here we highlight the presentation, diagnosis and available treatment modalities for the management of this rare anomaly.

Anomalous origin of coronary arteries typically from the contralateral sinus of valsalva was more common compared to anomalous origin of right or left coronary arteries from the PA
Summary
Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a very rare congenital heart defect. Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly. The incidence of ARCAPA is reported to be 0.002% in the literature and represents 0.12% of coronary anomalies[1].
