116 artial pulmonary venous return anomaly (PPVRA) is described as drainage of one or more pulmonary veins into the right atrium or to a systemic vein. This abnormal venous return may be towards the superior and inferior vena cava, the azygos vein, the portal or the hepatic veins.1 This cardiac anomaly is a very rare. The prevalence of this, 0.1-0.2% in adult population reported.2 Mostly, abnormal right pulmonary veins (especially right upper pulmonary veins) are opened to the right atrium (RA) or superior vena cava (SVC). The left-sided PPVRA may be drained into the innominate vein, hemiazygos vein and coronary sinus.1 PPVRA is commonly associated with atrial septal defect (ASD) and other congenital heart anomalies.1 PPVRA is seen in approximately 10-15% of ostium secundum ASD cases and 85% of patients with sinus venosus ASD.3
