This is a multi-center prospective, single-arm, non-randomized, open label study to assess safety and performance of the Xeltis Pulmonary Valved Conduit in subjects requiring Right Ventricular Outflow Tract correction or reconstruction due to congenital heart malformations.

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
