Inclusion Criteria

1. Patient requiring RVOT reconstruction, suitable for 16 mm or 18 mm valved conduit.
2. Male or Female.
3. Age < 22 years.
4. Right Ventricular to Pulmonary Artery mean gradient > 35mm Hg or moderate or severe Pulmonary regurgitation (≥3+), or have both.
5. The patient, and the patient's parent / legal representative where appropriate, has been informed of the nature of the study, agrees to its provisions and has provided written informed consent by signing the approved informed consent form.
6. The patient, and the patient's parent / legal representative where appropriate, and the treating physician agree that the subject will return for all required post-procedure follow up visits and the subject will comply with clinical investigation plan required follow-up visits.

Exclusion Criteria

1. Need for or presence of prosthetic heart valve at other position
2. Need for concomitant surgical procedures (non-cardiac)
3. Patients with previously implanted pacemaker (including defibrillators) or mechanical valves
4. Active bacterial or viral infection or requiring current antibiotic therapy (if temporary illness, patient may be a candidate 4 weeks after discontinuation of antibiotics)
5. Active endocarditis
6. Leukopenia, according to local laboratory evaluation of white blood cell count
7. Acute or chronic anemia, according to local laboratory evaluation of hemoglobin Patients can be transfused to meet eligibility criteria
8. Thrombocytopenia, defined as Platelet count < 150,000/mm3 Patients can be transfused to meet eligibility criteria
9. Severe chest wall deformity, which would preclude placement of the PV conduit
10. Pulmonary hypertension (right ventricular systolic pressure ≥ half of systemic systolic pressure)
11. Right ventricular outflow tract aneurysm
12. Known hypersensitivity to anticoagulants and antiplatelet drugs and to the device materials
13. Immunocompromised patient defined as: autoimmune disease, patients receiving immunosuppressant drugs or immune stimulant drugs
14. Patient has chronic inflammatory / autoimmune disease
15. Need for emergency cardiac or vascular surgery or intervention
16. Major or progressive non-cardiac disease (liver failure, renal failure, cancer) that has a life expectancy of less than one year
17. Currently participating, or participated within the last 30 days, in an investigational drug or device study
18. Alcohol or drug abuse as defined by DSM IV-TR criteria for substance abuse - this includes the illicit use of cannabis within the last 12 months
19. Females who are sexually active and are not willing to use adequate contraceptive precautions for the next 2 years
20. Patient has medical, social or psychosocial factors that, in the opinion of the Investigator, could have impact on safety or compliance

Arm && Interventions

Group	Intervention	Description
Xeltis Pulmonary Valved Conduit	Xeltis Pulmonary Valved Conduit	PV Conduit for RVOT reconstruction

Primary Outcome Measures

Name	Time	Method
Survival at 12 months follow up post implantation	12 months	Measured by the fact that the patient is still alive at the time of the 12 month FU visit

Secondary Outcome Measures

Name	Time	Method
Mean pressure gradient across the area of conduit implantation (RV to PA) of less than 40 mm Hg at 12 months follow up	12 months
Pulmonary regurgitation of equal or less than moderate (≤40 %) at 12 months follow up	12 months
Freedom from device related death, intervention and/or reoperation at 12 months follow up	12 months	Measured by the fact that the patient did not die, did not have a reoperation or reintervention during the first 12 months
