Transcatheter treatment of partial anomalous pulmonary venous connection to left subclavian vein

Abstract

Reports of transcatheter treatment for dual drainage of an abnormal pulmonary venous connection are rare. Presently described is the case of a 27-year-old female with exertional dyspnea and a partial anomalous pulmonary venous connection of the left upper pulmonary vein with dual drainage to a vertical vein (VV) and the left atrium. The patient was evaluated with a balloon occlusion test to determine whether closing the anomalous VV connection would increase pulmonary pressure. The results of this test are an important guide to treatment decisions. A 12x9 mm Amplatzer Vascular Plug II device was successfully used to occlude the anomalous pulmonary venous connection using a transcatheter technique. This is a less invasive option than surgical repair and can be an appropriate choice in suitable cases.
