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.
