Recruiting now NCT03142152
Run by Cardiac Dimensions, Inc. · for 18 and older · All sexes
What this study is about
The objective of this prospective, randomized, double- blinded (patient and assessors), sham-controlled clinical trial is to assess the safety and efficacy of the CMCS in treating heart failure with functional regurgitation (FMR).

- LVEDD:
- ≥ 55 mm (women)
- ≥ 57 mm (men)
- LVESD ≤ 75 mm
- Corrected NT-proBNP > 1200 pg/ml measured within 60 days of randomization, and/or one or more heart failure hospitalizations within one year prior to consent or one or more outpatient visits for intensification of heart failure therapy within one year prior to consent.
- Optimal Guideline directed heart failure medical therapy assessed by the Central Review Committee
- Age ≥ 18 years old
- Carillon implant can be sized and placed in accordance with the IFU

🚫 You may not be able to join if…
- Presence of a mechanical or bio-prosthetic mitral valve or, mitral valve annuloplasty, or leaflet repair device
- 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)
- Severe tricuspid regurgitation associated with right ventricular dysfunction and enlargement
- Severe mitral annular calcification
- Severe aortic stenosis
- Expected to require any cardiac surgery, including surgery for coronary artery disease (CAD) or valve disease within one (1) year
- 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 judgement of the Investigator or Central Review Committee, makes the patient a poor candidate for this study
- An entire list of eligibility is available in the clinical investigational plan
