Percutaneous occlusion of right partial anomalous pulmonary venous connection with dual drainage to the innominate vein and the left atrium: A unique anatomical finding

Abstract

A 43-year-old woman with a past medical history of aortic coarctation surgically repaired at the age of 3 years usinganend-to-endanastomosis,pre-sented with 2 years complain of increasing dyspnea and fatigue with exercise associated to frequent palpitations. During extensive work-up, she was found to have a partial anomalous pulmonary venous connection (PAPVC) with “dual drai-nage” represented by a communication between the right pulmonary veins drain-ing into the left atrium and the innominate vein via an anomalous vein due to a persistence of early connections between the sinus of the right pulmonary veins and the cardinal veins system in the splanchnic plexus and also a persistence of the proximal portion of the left anterior cardinal vein. She was successfully treated through a percutaneous implantation of a vascular plug occluding the vertical portion of the anomalous vein diverting the flow to the left atrium. To the best of our knowledge, this anatomical variant of partial anomalous pulmonary venous connection with dual drainage has not been previously reported.
