Mid-term results of bioprosthetic pulmonary valve replacement in pulmonary regurgitation after tetralogy of Fallot repair

Abstract

PVR reduced the RV volume and improved the RV function within the first postoperative year. The rate of freedom from reoperation during the 10-year follow-up period in our series was acceptable. However, a longer follow-up will be necessary to determine the long-term outcomes of bioprosthetic valves in PVR.
