TAPVR stands for?

• A. Total Anomalous Pulmonary Venous Return
• B. Total Anomalous Pulmonary Trunk Venous Return
• C. Trunk Anomalous Pulmonary Venous Return
• D. Transient Anomalous Pulmonary Venous Return

Answer: (B)

TAPVR stands for Total Anomalous Pulmonary Venous Return. This congenital defect means all four pulmonary veins do not connect to the left atrium as they should; instead they drain abnormally into the right atrium or into systemic venous circulation. Because the oxygenated blood is returning to the right side of the heart, there’s mixing with deoxygenated blood, and an interatrial communication (usually an ASD) is needed to allow some blood to reach the left atrium and systemic circulation. There are several drainage patterns (supracardiac, cardiac, infracardiac, mixed), and newborns often present with cyanosis and respiratory distress. Surgical repair aims to re-route the pulmonary venous return to the left atrium. The term involving a pulmonary trunk in the name is not correct, which is why the accurate expansion uses “Venous Return.”
