Percutaneous Pulmonary Valve Replacement
OHSU is one of only a few centers in the nation to implant pulmonary heart valves without open-heart surgery. A device, called the Medtronic Melody Transcatheter Pulmonary Valve, can be implanted by using a catheter threaded from a small incision in the blood vessel in the leg up to the heart. The Melody valve is used to replace a narrow or leaky pulmonary valve in children and adults who previously have undergone surgery to correct a congenital heart defect. Until now, pulmonary valve replacements have required open-heart surgery.
Who is a candidate for the Melody Transcatheter Pulmonary Valve?
The FDA has approved use in children and adults with failed right ventricle-to-pulmonary artery conduits. This percutaneous therapy is an adjunct to surgery for patients with dysfunctional RVOT conduits whose pulmonary valve has become stenotic (blocked) or regurgitant (wide open with little or no valve function).
