The study tests a new heart valve called the SAPIEN 3. It's for people with a problem in the pulmonary valve, which is part of the heart that helps blood go to the lungs. This study checks if the new valve is safe and works well. **Eligibility** includes those who weigh at least 44 pounds and have a specific heart issue needing treatment. The heart issue involves the right side of the heart, where blood flows to the lungs, being too narrow or having a faulty valve. Some people cannot join, like those with certain infections, blood problems, or who are pregnant.
- This study involves a procedure to put in the new valve.
- Participants will be checked often to ensure the valve is working and they are safe.
- There are risks, like with any heart procedure, and it's important to discuss with doctors.
