This study will assess a device that combines CCM® Therapy and a single-chamber defibrillator for patients with heart failure and reduced ejection fraction.


You may be eligible for the study if you have been diagnosed with all of the following:

  • Symptomatic NYHA Class III heart failure
  • A left ventricular ejection fraction (LVEF or EF) that is 25 – 35%
  • An NYHA Class I indication for an ICD

Full details and contact information on the study and participating hospitals will be updated regularly.
