Study Summary
This trial is testing a new heart valve to see if it is safe and effective in people with a dysfunctional right ventricular outflow tract/pulmonary valve. If the trial is successful, subjects will be eligible for enrollment in the continued access phase.
Who is the study for?
This trial is for individuals weighing at least 44 lbs with certain heart conditions like Tetralogy of Fallot, who have moderate or severe pulmonary regurgitation. They must have specific measurements in their heart's outflow tract and agree to the study terms. People can't join if they've had recent medical procedures, drug abuse history, are pregnant, have serious non-cardiac diseases, infections requiring antibiotics, blood disorders or known allergies to specific metals and medications.Check my eligibility
What is being tested?
The ALTERRA trial tests the safety and effectiveness of combining two devices: the Edwards Alterra Adaptive Prestent and SAPIEN 3 THV System. This combo aims to treat patients with dysfunctional right ventricular outflow tracts/pulmonary valves due to congenital heart defects.See study design
What are the potential side effects?
Potential side effects may include complications related to device placement such as bleeding or infection at the insertion site, allergic reactions to materials in the devices or contrast media used during implantation, irregular heartbeat patterns (arrhythmias), valve leakage or migration.
