We hope you and your loved ones are safe as we all manage the impacts of the COVID-19 pandemic. For the ongoing CARILLON Trial, protecting the safety of patients and researchers is paramount. In this spirit, Cardiac Dimensions has temporarily paused new trial enrollment, effective May 8, 2020. We are continually monitoring the global pandemic and will resume trial enrollment when it is safe to do so.

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. 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.

Trial sites are currently located in the U.S., U.K., Poland, Greece and France. Interested patients may find out more about the trial at Clinical Trials (click here).
