SAN DIEGO, May 6 /PRNewswire/ -- An innovative catheter-based procedure is providing relief to patients who suffer from shortness of breath and fluid overload as the result of a severely leaky heart valve, but who are too sick for open-chest surgery, according to a study presented today at the Society for Cardiovascular Angiography and Interventions (SCAI) 33rd Annual Scientific Sessions.
Data from the Endovascular Valve Edge-to-Edge REpair STudy (EVEREST II) High Risk Registry showed that, in patients who are not healthy enough to undergo surgery to repair a leaky mitral valve, use of the MitraClip valve repair system is safe and, in the majority of patients, effective in relieving symptoms that limit the ability to engage in day-to-day activities. There has never been a treatment option for this high-risk group of patients in the past.
"The MitraClip system is a first-in-class treatment and a remarkable innovation—the beginning of a very exciting era for treating valvular disease with minimally invasive devices," said Saibal Kar, M.D., FSCAI, director of interventional cardiac research at the Heart Institute, Cedars Sinai Medical Center, Los Angeles.
The mitral valve controls blood flow between the atrium (upper chamber) and the ventricle (lower chamber) on the left side of the heart. A leaky mitral valve, or mitral regurgitation, can develop when the valve flaps, or leaflets, do not close effectively. This can happen either because the valve flaps are scarred or defective, or because the heart has become enlarged, stretching the valve opening so much that the flaps no longer meet in the center.
Mitral regurgitation is the most common condition involving the valves of the heart. Of the 25
