Transcatheter Pulmonary Valve Replacement from Autologous Pericardium with a Self-Expandable Nitinol Stent in an Adult Sheep Model

Yimeng Hao^1,2, Xiaolin Sun^1,2, Jonathan Frederik Sebastian Kiekenap¹, Jasper Emeis¹, Marvin Steitz², Alexander Breitenstein-Attach², Felix Berger^1,2, Boris Schmitt^1,2,3,4,5

This study demonstrates the feasibility and safety of developing an autologous pulmonary valve for implantation at the native pulmonary valve position by using a self-expandable Nitinol stent in an adult sheep model. This is a step toward developing transcatheter pulmonary valve replacement for patients with right ventricular outflow tract dysfunction.
