Communications between the atria are common. The most common interatrial communication is known as an oval fossa defect. However, other forms of interatrial communications such as superior or inferior sinus venosus defects and coronary sinus defects also exist. Because of differences in the management approach to different forms of interatrial communications, accuracy in the diagnosis of these defects is important for determining the method of closure.

Sinus venosus defects are interatrial communications which are “extraseptal,” not involving the true atrial septum. Superior sinus venosus defects involve a connection between the right upper pulmonary vein and the superior caval vein. This creates a communication between the right and the left atria. Inferior sinus venosus defects involve the right lower pulmonary vein and inferior caval vein in an analogous manner. As such, these defects are always associated with partial anomalous pulmonary venous return. They, in fact, more closely...
