Transcatheter occlusion of the vertical vein in a partial anomalous pulmonary venous connection with dual Drainage, case series with literature review

Partial anomalous pulmonary venous return (PAPVR) is an uncommon type of congenital heart disease occurring due to abnormal drainage of one or more, but not all the pulmonary veins to the systemic veins or directly to the right atrium. The PAPVR might have single (to the systemic veins) or dual drainage (to the systemic as well as left atrium). Management depends on the shunt impact on the heart and lungs, and it is usually surgical correction. In case of PAPVR with dual drainage, there is a new trend of percutaneous occlusion of the vertical vein with dual drainage anatomy, so that the blood is obliged to flow to the left atrium as in normal hearts. The scope of this manuscript is to highlight the availability of this alternative option and to present our experience and outcome in 6 PAPVR patients with dual drainage treated using this percutaneous approach.
