Overview

Echocardiography may be used as a diagnostic tool in the evaluation of an atrial septal defect. Common malformations of the septal wall include: ostium primum, ostium secundum, sinus venosus, and patent foramen ovale. Uncommonly, a defect may occur in the coronary sinus. Specific characteristics exist in echocardiography to identify these classifications of atrial septal defects.

Echocardiography and Sinus Venosus Defects

Characteristics of sinus venosus defects include:

• Seen best in the subcostal four-chamber view by paying special attention to the superior and posterior portions of the atria.
• Occurs at the top of the septum near the insertion of the superior vena cava.
