Modified Hand-Sewn Polytetrafluoroethylene Bicuspid Valved Conduit for the Reconstruction of Right Ventricle Outflow Tract in Truncus Arteriosus in Infancy: A Case Report

Abstract

The reconstruction of the right ventricle outflow tract in truncus arteriosus remains challenging. The use of valved conduit based on polytetrafluoroethylene has been increasingly popular since the 1990s. Albeit with verified long-term durability, the previous techniques for manufacturing polytetrafluoroethylene valved conduit were relatively cumbersome and time-cost, which at least in part limited its further application. We reported the first successful truncus arteriosus case using a modified and simplified technique for hand-sewing the polytetrafluoroethylene pulmonary bicuspid valved conduit. Eventually, the patient completed the surgery successfully and showed a satisfactory outcome during the 17-month follow-up. Therefore, this technique is a time-saving, reproducible, and reliable approach in truncus arteriosus on the reconstruction of the right ventricle outflow tract.
