PH failure (table 3):
PH failure occurred in 12 patients (11.7%) during follow-up. Mean time before PH failure was 5.00 ± 4.35 years. PH failure resulted in PH stenosis in 11 patients (10.1%) and 2 patients (1.8%) presented PH disease (significant PS and PR > grade 2). Among these patients, 4 (3.9%) were re-operated of the PH and the 8 others patients (7.7%) who presented PH failure were not re-operated because they did not present criteria for re-intervention according to the European Guidelines [10]. Freedom from PH failure at 1, 5 and 10 years was respectively 100%, 93.4% and 81.6% (Figure 2).
