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).
