The COAPT Trial


  • Mitral regurgitation

Study Name:

Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (The COAPT Trial)


Phase 3


The purpose of this study is to examine the safety and effectiveness of an investigational device called the MitraClip® System in patients with functional mitral regurgitation (FMR). The device consists of a delivery catheter and an implantable clip; the catheter guides the MitraClip System into place so that it can be attached to the leaflets (tissue) of the patient's mitral valve. Once the MitraClip is in place on the mitral valve, the delivery catheter is removed.

FMR occurs when the two leaflets of the mitral valve do not close properly, causing blood to leak backward with each heartbeat. If left untreated, patients may begin to show symptoms of heart failure.
