Use of Right Atrial Appendage Tissue for Pulmonary Valve Reconstruction in Tetralogy of Fallot.

We explore the innovative use of atrial appendage tissue for creating pulmonary valves in children, focusing on its application in Tetralogy of Fallot repair. We discuss the background, preclinical studies, surgical approach, and early clinical outcomes, demonstrating the potential of this technique in reducing pulmonary insufficiency and improving surgical outcomes.
