Catheter-Delivered Valve May Help People With Heart Defects Avoid Multiple Surgeries

lains. "Because conduits may develop regurgitation or obstruction relatively quickly, we almost inevitably end up accepting some degree of dysfunction, often for many years, because patients can't keep going for surgery every couple of years."

Chronic conduit dysfunction can cause symptoms and eventually lead to dysfunction of the ventricle. Because the transcatheter valve can be implanted without the risks and morbidity of surgery, the threshold for intervening can be lowered, offering patients a chance at an improved quality of life, preserved heart function and fewer surgeries, McElhinney says.

"Of course, we need to learn more before we know whether the promise of this technology is realized," he adds.

The study was supported by Medtronic, Inc., manufacturer of the Melody valve. For more on the study, see http://www.childrenshospital.org/newsroom/Site1339/mainpageS1339P1sublevel293.html.
