A Rare Case of Partial Anomalous Pulmonary Venous Connection.

Partial anomalous pulmonary venous connection (PAPVC), in which the right and left lower pulmonary veins drain into the coronary sinus (CS), is very rare, and only one case has been reported previously. The diagnosis of PAPVC is difficult, as the symptoms may be not specific. Multidetector computed tomography (MDCT) angiography and MRI help in the diagnosis of congenital cardiac anomalies. Our case, who underwent closure of atrial septal defect (ASD) 31 years prior, presented with chest tightness and palpitation. MDCT angiography revealed PAPVC with both lower pulmonary veins draining into the CS. We performed surgical repair of PAPVC by the cut-back method. The postoperative course was uneventful.
