Vsling™ I: Clinical Evaluation of the Vsling™ Device for Ventricular Repair in Patients With Heart Failure

This study is testing a new implantable device called the Vsling, which is placed around the heart through a minimally invasive procedure to physically support a weakened, enlarged heart and help it pump more efficiently in patients with heart failure. **You may be eligible if...** - You are 18 years of age or older - Your left ventricle (main pumping chamber) is significantly enlarged (end diastolic diameter ≥ 55 mm) - Your heart's pumping function (ejection fraction) is between 20% and 40% - Your heart valve leakage (mitral regurgitation) is mild or less - You have moderate-to-severe heart failure symptoms (NYHA Class II–IVa) - Your heart failure is caused by ischemic or non-ischemic dilated cardiomyopathy **You may NOT be eligible if...** - Your ejection fraction is below 20% or above 40% - Your mitral valve leakage is moderate or greater - You have had a recent heart attack or heart surgery - You have a mechanical heart valve or a device that would interfere with the Vsling - You are listed for or have had a heart transplant Talk to your doctor to see if this trial is right for you.
