The pulmonary valve is the heart valve that allows blood to flow from the right ventricle to the lungs.

When a pulmonary valve doesn't function properly, it can be life-threatening. Replacing the diseased valve can restore good blood flow. However, children can outgrow their replacement valves and may need repeat procedures. Adults with leaky replacement valves may also require additional interventions.

Transcatheter pulmonic valve replacement (TPVR) is a minimally invasive procedure designed to treat pulmonary valve disease and reduce the need for open-heart surgery. This advanced technique allows for a lifetime of pulmonary valve management with fewer surgical interventions.

The transcatheter valve used in TPVR is designed to accommodate a range of patient sizes. For smaller patients, including children, the valve can be cinched down and later expanded as they grow. This adaptability means some future adjustments can be performed using catheter-based techniques rather than open-heart surgery.

Transcatheter Pulmonic Valve Replacement: What to Expect

Before the procedure, you will receive medication to ensure you are asleep and comfortable.

Your interventional cardiologist will make an incision in a blood vessel and insert a thin, flexible tube (catheter) with a balloon-mounted replacement valve at its tip.

Once in position, the balloon is inflated to expand the valve and secure it in place. The balloon and catheter are then removed.

The new valve begins functioning immediately, and future adjustments can be made using similar minimally invasive methods if needed.
