Surgical Approaches to Total Anomalous Pulmonary Venous Connection.

Total anomalous pulmonary venous connection (TAPVC) constitutes a spectrum of congenital lesions whereby the pulmonary veins remain connected to systemic venous vessels or aberrantly connect to the right atrium. Definitive management requires surgical intervention and, in patients with obstruction to pulmonary venous flow, urgent operation is required. Use of temporizing catheter-based interventions allow for optimization in hemodynamically unstable neonates. Overall, survival has significantly improved over the past decades through better perioperative management and evolution of surgical approaches to minimize post-repair pulmonary vein stenosis, which persists as a major determinant of long-term outcomes.
