Results :
Mean age of the recipients was 26.13 ± 13.59 years. Mean size of PH was
23.02 ± 6.87 mm. Re-operation of the RVOT occurred in 8 patients
(7.8%). Time before re-operation was 2.74 years (Interquartile Range:
6.41). Freedom from re-operation for RVOT at 5 and 10 years was
respectively 95.7% and 90.0%. Overall survival at 10 years was 95.2%.
PH failure occurred in 13 patients (12.0%). Mean time before PH failure
was 5.00 ± 4.35 years. Freedom from PH failure at 10 years was 81.6%.
Re-operation for PH failure occurred in 4 patients (3.9%). Concomitant
tricuspid valve surgery (p=0.037), initial pulmonary stenosis (p=0.04),
recipient of PH < 16 years old (p=0.043) were risk factors of
late reoperation in univariate analysis. Multivariate analysis showed no
independent risk factor of late reoperation.
