Abstract
We present two cases of sinus venosus type atrial septal defect associated with right anomalous pulmonary venous return to the superior vena cava with echocardiography and computed tomography angiography. Sinus venosus type atrial septal defect is a rare anomaly and can be diagnosed with transesophageal or transthoracic echocardiography. However it is often difficult to detect associated pulmonary venous return anomalies and other congenital anomalies with echocardiography. Multidedector CT is a non-invasive technique that may provide useful information on localization and dimensions of ASD and associated anomalies. It is also important to detect these anomalies prior to cardiac and aortic surgical procedures.
Keywords: Atrial septal defect, pulmonary veins/abnormalities, computed tomography.
