Possible Risks Associated with Melody TPV
As with any medical procedure, there is a risk of side effects or complications during or after the Melody TPV procedure, which may be serious, including death. Complications that may occur during or after this procedure include:
- Pain, swelling, and bruising at the site where the thin, hollow tube (catheter) entered your body
- Bleeding or pain at the site where the thin, hollow tube (catheter) entered your body
- Reddening, peeling, or blistering of the skin due to x-rays
- Irregular heart beat
- Tearing of the blood vessel where the thin, hollow tube (catheter) is inserted
- Tearing of a heart chamber or the pulmonary conduit
- Allergic reaction to the x-ray dye
- Stroke (a condition in which decreased blood flow to the brain causes brain cells to die)
- Breakage of the wire frame (stent fracture) that supports the tissue valve
- Leakage or narrowing of the valve
- Infection of the valve (endocarditis)
- Tearing of the conduit during the procedure
- Squeezing of the arteries near the failed conduit when the stent or valve is expanded
- Development of a blood clot within the valve which affects its function or travels to the lung
- Movement of the valve from where it was implanted
- Breakdown of red blood cells
- Leakage of blood around the valve or valve frame
- Poking a hole in a large vessel (perforation)
Melody TPV Therapy Benefits
Restored pulmonary valve conduit function1
- Relief of narrowing (stenosis)
- Relief of leaking (regurgitation)
Increased pulmonary valve conduit lifespan1
- Delay of a patient’s next open-heart surgery

Important Information About Stent Fracture
In some patients, the wire frame (stent) of the Melody TPV may fracture because of the forces it is exposed to in your body. In some cases, the fractured stent may not require additional treatment.
However, you should realize a fractured stent has the potential to become serious and could result in the need for another procedure to replace your conduit. Your doctor will decide your best treatment option. There is up to a 3% chance that your Melody TPV stent will break within one year of placement, requiring you to have another procedure.

Additional Warnings and Precautions
The safety and effectiveness of the Melody Transcatheter Pulmonary Valve (TPV) has only been established in patients who have a narrowed or leaky pulmonary conduit.
The safety and effectiveness of the Melody Transcatheter Pulmonary Valve has not been proven in the following:
- Patients who have a disease of their aortic valve (valve that controls blood from the heart to the body) or mitral valve (valve that controls blood from the top left chamber of the heart to the bottom left chamber of the heart). The Melody TPV may not work properly when used in these locations.
- Patients whose blood vessels are not big enough for the device
- Patients who have an infection in the heart (endocarditis) or somewhere else in the body
