Patients:
Between January 2000 and December 2017, 232 patients underwent PH implantation for RVOT reconstruction. Only patients who received a PH for isolated RVOT reconstruction for correction of a right side congenital heart disease were included in this single-center retrospective study. Patients who received PH concomitant left ventricular outflow tract (Ross procedure, Ross-Konno Procedure, aortic valve replacement, Bentall or Tirone David procedures) reconstruction were excluded from the analysis. Clinical data and echocardiographic data were retrospectively collected using patient’s clinical records and operative reports available in the University Hospital of Nantes during the study period.
