NHLBI DIR Transcatheter Mitral Cerclage Annuloplasty Early Feasibility Study

Plain-language summary
This research protocol tests a new technique and devices that we have developed to treat functional mitral valve regurgitation, called transcatheter mitral valve cerclage annuloplasty, otherwise known as "cerclage". Functional mitral valve regurgitation is a condition caused by damaged heart muscle involving the left ventricle which results in mitral valve leakage. This leakage causes heart failure (breathlessness and lack of energy especially when walking or exercising, and hospital admissions for fluid buildup).
This is an early feasibility study (EFS) evaluation of special devices, permanently implanted in the heart, to perform mitral cerclage annuloplasty. Mitral cerclage annuloplasty is a catheter procedure performed under X-ray and ultrasound guidance without surgery. The cerclage devices compress the mitral valve like a purse-string. The cerclage device has a special feature that prevents a coronary artery from getting squeezed as part of this purse-string.
The protocol has been changed to allow patients who have mitral valve regurgitation despite prior Mitra-Clip treatment, and to allow patients who have symptomatic heart failure with mild mitral regurgitation.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
. Mild or greater mitral valve regurgitation, LVEF \<= 0.50, and NYHA class III - IV heart failure
. Moderate or greater mitral valve regurgitation and NYHA II - IV heart failure, irrespective of LV systolic function
. On optimal medical therapy for at least one month
. Left ventricular ejection fraction \>=0.20 assessed by echocardiography, CT, or CMR
. Suitable coronary venous anatomy for Transcatheter Mitral Cerclage Annuloplasty based on pre-procedural cardiac CT or coronary venogram
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
