Late Pulmonary Valve Replacement after Correction of Fallot's Tetralogy

Abstract

PVR after Fallot repair is frequently required because of progressive RV enlargement with dysfunction. It can be performed with relatively low risk, even in the setting of multiple reoperation. Obstructive lesions (RVOTO, PA stenosis) and residual defects are frequently observed in patients needing late PVR and may play a crucial role in the development of RV failure. Timely valve replacement with repair of all obstructive lesions proximal and distal to the implanted valve is the key to preserving RV function.
