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.
