# "Tricuspid valved patch" repair with a polytetrafluoroethylene valved conduit for right ventricular outflow reconstruction

## TL;DR

A new surgical technique using a handmade polytetrafluoroethylene valved conduit is proposed for right ventricular outflow reconstruction in patients with repaired tetralogy of Fallot.

## Contribution

The novel technique uses a handmade polytetrafluoroethylene tricuspid valved conduit for right ventricular outflow reconstruction.

## Key findings

- The tricuspid valved conduit provides reliable valvular function.
- The technique offers favorable biocompatibility and growth potential for young patients.

## Abstract

As an alternative to bioprosthetic pulmonary valve replacement for patients with late pulmonary insufficiency of repaired tetralogy of Fallot, we developed a novel technique using a handmade polytetrafluoroethylene tricuspid valved conduit, wherein the 2 posterior sinuses of the valve were resected and interdigitated with the native tissue of the pulmonary sinuses, followed by augmentation of the pulmonary trunk with the anterior wall of the conduit. Reliable valvular function of the tricuspid valve and the favorable biocompatibility of polytetrafluoroethylene material along with the growth potential of the repaired right ventricular outflow tract suggest that it may be an optimal alternative especially for young patients.
