Partial anomalous pulmonary venous return with secundum atrial septal defect: A case report.

Partial anomalous pulmonary venous return (PAPVR) is a congenital heart anomaly in which some of the pulmonary veins return to the right atrium or one of its supplying veins instead of normally connecting with the left atrium. Oftentimes it is concurrent with a secundum atrial septal defect. PAPVR is typically asymptomatic, however symptoms of pulmonary hypertension can arise at higher degrees of left-to-right shunting. An 80-year-old male presented with exertional dyspnea and was found to have a secundum atrial septal defect on echocardiogram. A subsequent contrast enhanced computed tomography of the chest revealed a concomitant PAPVR.
