What side effects are associated with this type of intervention?

Common treatments for Tetralogy of Fallot, particularly those involving Right Ventricular Outflow Tract Reconstruction (RVOTR) such as surgical repair and valve replacement, can have several side effects. These may include arrhythmias, residual or recurrent pulmonary valve regurgitation, right ventricular dysfunction, and potential need for re-intervention. Other risks include infection, bleeding, and complications related to the use of prosthetic materials or devices.

What prior FDA approvals exist?

The FDA has approved various treatments for Tetralogy of Fallot, primarily focusing on surgical interventions such as complete surgical repair, which includes procedures like ventricular septal defect closure and right ventricular outflow tract reconstruction. Devices similar to those being studied in the MASA Valve trial, such as pulmonary valve replacement devices, have also been approved. These devices aim to improve the function of the right ventricular outflow tract and are crucial for patients requiring reconstruction due to congenital heart defects.

What other types of research exist?

Promising novel alternatives to the MASA Valve for RVOTR in Tetralogy of Fallot patients include the Melody Transcatheter Pulmonary Valve and the Edwards SAPIEN XT Transcatheter Heart Valve. Both devices have shown positive outcomes in clinical trials for RVOTR and are minimally invasive options that can be considered for patients requiring pulmonary valve replacement.

Summary

This trial is to test the safety and effectiveness of a new valve for people who need surgery to repair or replace their right ventricular outflow tract. The trial will help determine if the new valve is safe and effective enough to be used in future patients.

Who is the study for?

This trial is for children and young adults under 22 with certain heart conditions needing surgery to fix blood flow from the right ventricle to the pulmonary artery. They must be able to return for follow-ups, have a legal guardian's consent, and not be involved in other drug/device trials or have severe non-cardiac diseases.Check my eligibility

What is being tested?

The MASA Valve Early Feasibility Study tests a new device called MASA Valve in patients requiring surgical reconstruction of the pathway from the heart's right ventricle to the lung arteries (RVOTR). It aims to assess safety and potential benefits as preliminary research before larger studies.See study design

What are the potential side effects?

While specific side effects are not listed, typical risks may include reaction to materials in the device, complications from heart surgery like bleeding or infection, and potential need for future surgeries if issues arise with valve function.

Prior Approvals

Other Research

Tetralogy of Fallot (TOF) treatments often involve surgical interventions to correct anatomical defects, particularly focusing on relieving right ventricular outflow tract (RVOT) obstruction. The MASA Valve trial, which studies a device for RVOT reconstruction, is significant for TOF patients as it directly addresses this obstruction. By relieving RVOT obstruction, these treatments reduce right ventricular pressure and improve blood oxygenation, thereby restoring normal blood flow dynamics and reducing the risk of complications such as right ventricular hypertrophy and heart failure.
