Primary and secondary endpoints:
Primary endpoint was the re-operation of the RVOT in patients who
previously underwent RVOT reconstruction with a PH. Secondary endpoints
were the overall survival of patients who underwent RVOT reconstruction
with a PH, the rate of re-operation for all causes of the patients
implanted with a PH for RVOT and the occurrence of PH failure (peak of
pulmonary gradient > 40 mmHg and/or pulmonary regurgitation
> grade 2).
