There may be more paths forward than you’ve been told.
Too many patients hear “there’s nothing more we can do” — and stop looking. That’s exactly the moment the HIP exists for.
Clinical trials test treatments that aren’t available anywhere else yet — often for patients who don’t qualify for anything else. Even if a second or third opinion has left you without treatment options, you can ask your care team whether a clinical trial may be relevant.
Eligibility depends on your diagnosis, history, and location — the HIP team or your cardiologist can help you figure out if you qualify.
First, what is a clinical trial?
A clinical trial is a carefully supervised study of a treatment that is not yet available to everyone. It is not an experiment done to you. You are looked after by a full medical team, usually more closely than in ordinary care, and you can stop taking part at any point, for any reason.
Every trial has rules about who can join, based on your diagnosis, your history, and sometimes your age or where you live. That is why some people qualify and others do not. Taking part is free of charge for the treatment being studied.
For valve conditions that do not yet have an approved option, or for people who have been turned away everywhere else, a trial is sometimes the way to reach a treatment years before it is widely available.
Why We Keep This List
We keep track of these studies so you do not have to search through medical databases on your own.

The unit of outcome measure is % (n/N): * Mortality: all-cause * Stroke: disabling and non-disabling; Bleeding: life-threatening based MVARC scale * Major access site vascular complications * Major cardiac structural complications due to access-related issues * Acute kidney injury (AKI; ≤7 days post index procedure): based on the Acute Kidney Injury Network (AKIN) --System Stage 3 (including renal replacement therapy) or Stage 2 * Myocardial infarction (MI; periprocedural \[≤48 hours\] or spontaneous \[\>48 hours\]) * Coronary ischemia requiring percutaneous coronary intervention (PCI) or coronary artery bypass graft * Any valve-related dysfunction, migration, thrombosis, or other complication requiring surgery or repeat intervention, 30 days post index procedure
- Primary Technical Success Endpoint, Technical Success (measured at exit from the catheterization laboratory) is defined per Mitral Valve Academic Research Consortium (MVARC ).

SUMMIT
Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation
Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Plan (MAC CAP). Subjects in the Randomized cohort were randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts were receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) was to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial would provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System would be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who were not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and were also not suitable for transcatheter repair with MitraClip, would be enrolled in the Non-repairable cohort. Subjects would be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.
