• Three-dimensional transthoracic echocardiography
• Adult congenital heart disease
• Atrioventricular septal defect

We present the case of a 54-year-old male with an intermediate atrioventricular septal defect (AVSD). He was referred to our institute for treatment of shortness of breath. Two-dimensional transthoracic echocardiography demonstrated an ostium primum defect of the atrial septum, a common atrioventricular valve with mild regurgitations, and an interventricular communication, which are the features of complete AVSD. However, three-dimensional transthoracic echocardiography (3D-TTE) could clearly visualize the tricuspid pouch (i.e., persistence of the tissue in the endocardial cushion), a feature of partial AVSD. 3D-TTE appears to be a useful modality for diagnosis of intermediate AVSD.
