Device Offers Hope for Patients With Leaky Heart Valve

(HealthDay News) -- A new device offers hope for patients with a leaky heart valve who are too sick for open-heart surgery, according to a study funded by the company that makes the device.

The Carillon Mitral Contour System acts like a belt to reshape an enlarged, leaky heart valve. The study found that the device safely treated leaky mitral valves even in patients with moderate-to-severe heart failure and reduced the backward flow of blood from the left ventricle to the left atrium.

After treatment, patients experienced less shortness of breath and reported a better quality of life, according to the study, which included 48 patients with moderate-to-severe functional mitral regurgitation, an enlarged heart, decreased cardiac pumping ability, heart failure and a reduced capacity for exercise.

Of those 48 patients, researchers were able to implant the device in 30 patients. The other 18 patients couldn't be treated with the device, because the heart's veins were too small, the device pressed on nearby coronary arteries and limited blood flow to the heart muscle, or the device didn't adequately reduce the backflow of blood through the mitral valve.
