SURGICAL REPAIR OF ISOLATED PARTIAL ANOMALOUS PULMONARY VENOUS CONNECTION WITHOUT ATRIAL SEPTAL DEFECT: A TWO PATIENT CASE SERIES USING DIFFERENT RECONSTRUCTIVE STRATEGIES

Abstract

Background: Partial anomalous pulmonary venous connection (PAPVC) without an atrial septal defect (ASD) is uncommon and may remain unrecognized until adulthood. Surgical repair can be challenging when the anomalous pulmonary veins drain high into the superior vena cava (SVC) or when pulmonary venous length is insufficient for direct, tension-free reimplantation
