Get Treatment for Mitral Regurgitation and Help Others Like You1

If you or a loved one have mitral regurgitation (MR), know you're not alone and you have options when it comes to treatment.


Learn more about this clinical trial

The CLASP IID/IIF clinical trial studies the PASCAL system, a device designed to repair the mitral valve with no open heart surgery.

This trial is meant for patients with mitral regurgitation who are high-risk candidates for open heart surgery. Talk to your doctor to determine if this trial is right for you.

What is Mitral Valve Regurgitation?2

Mitral regurgitation is a condition where the heart’s mitral valve doesn’t close properly, allowing blood to flow backward within the heart. This makes it difficult for your heart to pump enough blood throughout your body. Mitral regurgitation can make you feel tired or short of breath, and can lead to heart failure if left untreated.

Understand the Two Types of MR

Degenerative mitral regurgitation3-5

Degenerative mitral regurgitation (DMR), also known as primary mitral regurgitation, usually occurs due to a structural problem with the valve’s leaflets.

Functional mitral regurgitation3,4

Functional mitral regurgitation (FMR), also known as secondary mitral regurgitation, occurs when the valve has been stretched and its leaflets don’t close tightly.

Both DMR and FMR may be treated by repairing or replacing the mitral valve. Getting treated for MR could make the difference for your heart and quality of life.1,2,4

What is the PASCAL repair system?1-3

The Edwards PASCAL repair system is designed to repair your mitral valve through a minimally invasive procedure called transcatheter mitral valve repair. Your doctor places a thin tube through a vein in your leg to reach your heart, and then uses the PASCAL implant to repair your mitral valve.

What You Should Know About the CLASP IID/IIF Clinical Trial

This trial is intended to evaluate the PASCAL repair system and show it works just as well as a currently available FDA-approved device.6

New medical devices, drugs, vaccines, and other therapies are made available to people on a regular basis. However, before they can be offered to the public, they need to be studied for how safe they are and how well they work.

A clinical trial is a type of research conducted with volunteers that studies recently developed medications or treatments. If they are considered safe and effective, then they can help patients with all types of health conditions, including mitral regurgitation.7,8

The CLASP IID/IIF clinical trial will evaluate a new device designed to treat MR by repairing the mitral valve using a transcatheter procedure (no open heart surgery).9,10

  • A transcatheter procedure will be used to repair your mitral valve in this clinical trial
  • You will receive one of two therapies, the PASCAL system, which is under investigation in this study, or MitraClip, a commercially available treatment option6
  • This clinical study will allow doctors to understand how the PASCAL repair system works in patients like you

  • Depending on your diagnosis (DMR or FMR), you will be enrolled in either the CLASP IID or CLASP IIF group5,10
  • Your health will be monitored throughout the clinical trial and after implantation of the device. This will require you to come in for several follow-up visits over a 5-year period6
  • During the trial, you will have a team of experts—your Heart Team—to guide and support you from beginning to end. You can count on them to answer any questions and work closely with your doctor to provide care1,6

Regardless of which group you are assigned, you will be treated for MR through a minimally invasive transcatheter procedure.1
