What side effects are associated with this type of intervention?

Common treatments for Tetralogy of Fallot, particularly those involving pulmonary valve replacement and RVOT reconstruction, include surgical procedures such as complete intracardiac repair and the use of prosthetic valves or conduits. Known side effects of these treatments can include arrhythmias, residual or recurrent pulmonary valve regurgitation, right ventricular dysfunction, bleeding, infection, and the need for re-intervention due to valve degeneration or conduit obstruction. Long-term follow-up is essential to monitor and manage these potential complications.

What prior FDA approvals exist?

The FDA has approved several treatments for Tetralogy of Fallot, particularly focusing on pulmonary valve replacement and RVOT reconstruction. Notable approvals include the Melody Transcatheter Pulmonary Valve (TPV) and the Edwards SAPIEN XT Transcatheter Heart Valve, both designed for percutaneous valve replacement in patients with dysfunctional RVOT conduits. These devices offer less invasive alternatives to open-heart surgery, providing significant benefits in terms of recovery and outcomes for patients with congenital heart defects like Tetralogy of Fallot.

What other types of research exist?

Promising alternatives to the GORE PV1 Device for Tetralogy of Fallot patients include the Melody Transcatheter Pulmonary Valve (TPV) and the Edwards SAPIEN XT Transcatheter Heart Valve. Both devices have shown positive outcomes in clinical trials for pulmonary valve replacement and RVOT reconstruction. The Melody TPV is known for its minimally invasive approach and suitability for pediatric patients, while the Edwards SAPIEN XT offers a robust design with proven durability.

Summary

This trial will test the safety and effectiveness of the GORE PV1 Device, which is used to replace a damaged heart valve and repair a part of the heart. It targets patients who need their pulmonary valve replaced and their Right Ventricular Outflow Tract fixed. The device helps the heart pump blood more efficiently by taking over the function of the damaged valve and repairing the heart's structure.

Who is the study for?

This trial is for individuals aged 5 or older with a congenital heart defect requiring pulmonary valve replacement or RVOT reconstruction. It's not suitable for those with artificial valves elsewhere, pacemakers, or severe non-cardiac diseases like liver failure, renal failure, or cancer with a life expectancy under one year.

What is being tested?

The GORE PV1 Device is being tested in this study to see if it's safe and effective for replacing the pulmonary valve and reconstructing the Right Ventricular Outflow Tract (RVOT) in patients with certain heart conditions.

What are the potential side effects?

Potential side effects are not explicitly listed but may include complications related to device implantation such as infection, bleeding, arrhythmia, or issues specific to heart valve devices like clotting.

Other Research

The most common treatments for Tetralogy of Fallot (TOF) involve surgical interventions to correct the structural heart defects. These typically include closing the ventricular septal defect and relieving the obstruction in the right ventricular outflow tract (RVOT). The GORE PV1 Device, which focuses on pulmonary valve replacement and RVOT reconstruction, is particularly important for TOF patients as it addresses pulmonary stenosis. This improves blood flow from the right ventricle to the lungs, reduces right ventricular hypertrophy, and enhances overall cardiac function, which is essential for the patient's long-term health and quality of life.
