Guideline directed heart failure medication regimen 8. Age 18 years old 9. Carillon implant can be sized and placed in accordance with the IFU 10. The subject has been informed of the nature of the trial and agrees to its provisions, including the possibility of randomization to the Control group and returning for all required post-procedure follow-up visits, and has provided written willing to sign a consent form Who Should NOT Join This Trial: 1. Pre-existing device (e.g., pacing lead) in coronary sinus (CS) / great cardiac vein (GCV) or Class I indication for cardiac resynchronization therapy (CRT) 2. Presence of a mechanical or bio-prosthetic mitral valve or, mitral valve annuloplasty, or leaflet repair device 3. Significant organic mitral valve pathology (e.g., moderate or severe myxomatous degeneration, with or without mitral leaflet prolapse, rheumatic disease, full or partial chordal rupture) 4. Severe tricuspid regurgitation associated with right ventricular dysfunction and enlargement 5. Severe mitral annular calcification 6. Severe aortic stenosis 7. Expected to require any cardiac surgery, including surgery for coronary artery disease (CAD) or valve disease within one (1) year 8. Chronic, severe, medical conditions or pathology, other than heart failure, that will prevent likely survival beyond twelve (12) months or any other medical condition that, in the judgment of the Investigator, makes the patient a poor candidate for this study - An entire list of eligibility is available in the clinical investigational plan Always talk to your doctor about whether this trial is right for you.
