Transcatheter occlusion of partial anomalous pulmonary venous connection with dual drainage to left atrium

Transcatheter therapy for partial anomalous pulmonary venous connection with dual drainage is unique and rarely reported. We report a 69-year-old female with recurrent brain abscess and partial anomalous connection of the left upper pulmonary vein with dual drainage to the vertical vein (VV) and left atrium (LA). Transcatheter occlusion of the VV was done using an 18-mm St. Jude Amplatzer Vascular Plug II, thus redirecting the left-sided pulmonary venous drainage to LA. Careful evaluation of partial anomalous pulmonary venous drainage with cross-sectional imaging is essential to allow the delineation of dual connections, enabling a less invasive transcatheter treatment approach
