Complementary echo and CCTA findings with superior sinus venosus atrial septal defect

Abstract

A young female developed progressive dyspnea on minimal exertion. Echocardiography demonstrated a large right heart with severe pulmonary hypertension. Cardiac computed tomographic angiography then demonstrated a superior sinus venosus atrial septal defect with an anomalous right upper pulmonary venous drainage. Echo and CCTA were complementary in making a proper diagnosis.

Keywords: anomalous pulmonary venous return; atrial septal defect (ASD); superior sinus venosus ASD.
