If you have heart failure, you know how this condition affects your quality of life. Simple daily activities like preparing meals, visiting with friends, or even moving from room to room can require major effort and leave you exhausted. An estimated 26 million people suffer from heart failure worldwide, and the number is growing rapidly.

Nearly 75% of heart failure sufferers also have a leaky mitral valve, a condition known as mitral regurgitation (MR). Unfortunately, this further compromises the function of the heart – causing your heart failure to worsen over time.

If you struggle with heart failure symptoms or have been told you have a leaky valve, you may qualify for a new clinical study being offered at select US centers. The study is for the Carillon Mitral Contour System, an investigational implant designed to reshape the mitral valve and reduce leakage through a non-surgical approach.

Cardiac Dimensions is currently enrolling patients in our CARILLON Trial. Trial sites are currently located in the U.S., U.K., Poland, Greece and France. Enrolling trial sites can be viewed on the interactive map below. Please check back often as we add more sites regularly.

Interested patients may find out more about the trial at Clinical Trials (click here) and at New HF Trial (click here).
