MethodsĀ :
Between January 2000 and December 2017, 107 patients were implanted with PH for reconstruction of the RVOT. Data were collected retrospectively in this single-center study. PH failure was defined as a peak of gradient > 40 mmHg and/or as a pulmonary regurgitation > grade 2. Primary endpoint was the re-operation of the RVOT during follow-up. Secondary endpoints were overall survival, occurrence of PH failure and the rate of re-operation for all cause.
