Figure 2From: Partial anomalous pulmonary venous return and atrial septal defect in adult patients detected with 128-slice multidetector computed tomography A dilated right ventricle of the heart and superior sinus venosus atrial septal defect (ASD). A male patient with pulmonary hypertension and right-sided volume overload. Multidetector computed tomography documented a dilated right side of the heart (a) and a large superior sinus venosus ASD (b), which could not be confirmed with transthoracic echocardiography. RA = right atrium, RV = right ventricle, LA = left atrium.Back to article page
