Case of anomalous origin of right coronary artery from pulmonary artery associated with interrupted aortic arch type A, diagnosed by multidetector computed tomography angiography

Abstract

Anomalous origin of the right coronary artery from pulmonary artery (ARCAPA) is a rare congenital anomaly of the coronary circulation, which can be easily missed by echocardiography. Interrupted aortic arch (IAA) is another rare congenital cardiac abnormality that typically presents in the first few weeks of life. We present a case of ARCAPA associated with IAA diagnosed with the help of multidetector computed tomography angiography, in a 7-year-old boy.
