Sinus Venosus Defect and Partial Anomalous Pulmonary Venous Connection: Effect of Surgical Strategies on Sinus Node Function and Potential Obstruction of the Superior Vena Cava

Abstract

Objectives: Surgical repair of sinus venosus defect (SVD) with partial anomalous pulmonary venous connection (PAPVC) to the superior vena cava (SVC) or the right atrium (RA) should avoid long term complications like permanent sinus node dysfunction (SND) or obstruction of superior vena cava (SVC). We retrospectively reviewed our single center experience on patients who underwent cardio-surgical repair using single-patch, double-patch and modified Warden-technique.
