Arm Intervention/treatment
Experimental: Xeltis Pulmonary Valved Conduit
PV Conduit for RVOT reconstruction
Device: Xeltis Pulmonary Valved Conduit
RVOT reconstruction

Primary Outcome Measures :
  1. Survival at 12 months follow up post implantation [ Time Frame: 12 months ]
    Measured by the fact that the patient is still alive at the time of the 12 month FU visit

Secondary Outcome Measures :
  1. Freedom from device related death, intervention and/or reoperation at 12 months follow up [ Time Frame: 12 months ]
    Measured by the fact that the patient did not die, did not have a reoperation or reintervention during the first 12 months

  2. Mean pressure gradient across the area of conduit implantation (RV to PA) of less than 40 mm Hg at 12 months follow up [ Time Frame: 12 months ]
  3. Pulmonary regurgitation of equal or less than moderate (≤40 %) at 12 months follow up [ Time Frame: 12 months ]
