Hemodynamic Study of a Case of Anomalous Pulmonary Venous Drainage

Abstract

Complete drainage of the pulmonary veins into the right heart is one of the rarest and most severe congenital cardiac anomalies. The X-ray studies may suggest this diagnosis if pulmonary veins enter either coronary sinus or inferior vena cava. In the case reported, right heart catheterization and angiocardiography were used and the diagnosis of persisent left superior vena cava and partial direct drainage of the pulmonary veins into right auricle was made.
