Treating Mitral Regurgitation Before it Progresses

Mitral regurgitation (MR) places an extra burden on your heart and lungs, and your heart may have to work harder to function normally. The mitral valve is a heart valve that lies between the left atrium and left ventricle. The valve opens and closes to ensure that blood flows in only one direction. In mitral regurgitation, the valve does not close completely and blood leaks backward (regurgitates) into the left atrium.1 The more open the valve remains, the more blood regurgitates and the more severe the problem.

Symptoms of Mitral Regurgitation

In some cases, you may have MR but not experience any symptoms. In other cases, you may experience symptoms such as1,2:

Fatigue or inability to exercise

Sensation of feeling the heart beat (palpitations) or a rapid heartbeat

Dry, hacking cough 
(often worse when lying down)

SHORTNESS OF BREATH

Fainting

Swollen feet or ankles

  • Betty Vaughn
    Patient with mitral regurgitation

    “I had no symptoms until I was about 87. When I was going up and down the stairs, I couldn’t breathe. Then I got light-headed, and I got terribly, terribly tired. It was not living, it was existing.”


If you are experiencing any of these symptoms, talk to your doctor to receive a thorough examination and proper diagnosis. You should also promptly seek treatment if you notice that your symptoms are getting worse — for example, if the swelling in your feet and ankles has increased or if you find it more difficult to perform daily activities such as walking up the stairs.

WHAT CAN HAPPEN IF MITRAL REGURGITATION IS NOT TREATED?

Mitral regurgitation places an extra burden on your heart and lungs. Over time, some people may develop an enlarged heart because it has to work harder to pump blood through the body. If it is not treated, mitral regurgitation can cause other, more serious problems with your heart, such as heart failure. This is a condition that occurs when your heart can’t pump enough blood to meet the needs of your body.1

TREATMENT OPTIONS FOR MITRAL REGURGITATION

Treatment for mitral regurgitation depends on how severe your condition is, and if it’s getting worse.1,2 The goal of treatment is to improve your heart’s function while minimizing your symptoms and avoiding future complications.
 

MEDICAL MANAGEMENT

Medications may be prescribed to help manage symptoms of mitral regurgitation, such as diuretics for fluid buildup in the legs and lungs. However, these medications only treat the symptoms and do not address the underlying problem with your mitral valve that is causing your disease.
 

MITRAL VALVE SURGERY

Considered the most effective long-term treatment for mitral regurgitation, surgery gives you the greatest probability for a safe and effective solution over time. Several surgical procedures are available to repair or replace the mitral valve, including traditional open-heart surgery (with an incision over the chest and sternum), minimally invasive surgery that does not involve opening the chest, and less invasive robotic and transcatheter procedures.


SURGICAL MITRAL VALVE REPAIR
 

If mitral valve repair is an option for you, a surgical technique called an annuloplasty may be performed. This procedure typically involves the implantation of a device to tighten or replace the ring around the mitral valve (annulus) so that the valve leaflets can close properly. When needed, other techniques may be used to repair the valve.


SURGICAL MITRAL VALVE REPLACEMENT

If the mitral valve cannot be repaired, your doctor may recommend valve replacement with an artificial (prosthetic) valve. Two types of prosthetic mitral valves are available: mechanical or tissue.


TRANSCATHETER MITRAL VALVE REPAIR (TMVr)

TMVr with MitraClip™ therapy, is a less invasive procedure that may be an option for patients with severe mitral regurgitation. Unlike surgery, this procedure does not require chest incisions and temporarily stopping the heart. In this procedure, a clip will be implanted onto the center of your mitral valve. This reduces mitral regurgitation, and the valve continues to open and close on either side of the clip, allowing blood to flow through.

Important safety information

MITRACLIP CLIP DELIVERY SYSTEMS
INDICATION FOR USE

  • The MitraClip™ NTR/XTR System is indicated for the percutaneous reduction of significant symptomatic mitral regurgitation (MR ≥ 3+) due to primary abnormality of the mitral apparatus [degenerative MR] in patients who have been determined to be at prohibitive risk for mitral valve surgery by a heart team, which includes a cardiac surgeon experienced in mitral valve surgery and a cardiologist experienced in mitral valve disease, and in whom existing comorbidities would not preclude the expected benefit from reduction of the mitral regurgitation.
  • The MitraClip™ NTR/XTR System, when used with maximally tolerated guideline-directed medical therapy (GDMT), is indicated for the treatment of symptomatic, moderate-to-severe or severe secondary (or functional) mitral regurgitation (MR; MR ≥ Grade III  per American Society of Echocardiography criteria) in patients with a left ventricular ejection fraction (LVEF) ≥ 20% and ≤ 50%, and a left ventricular end systolic dimension (LVESD) ≤ 70 mm whose symptoms and MR severity persist despite maximally tolerated GDMT as determined by a multidisciplinary heart team experienced in the evaluation and treatment of heart failure and mitral valve disease.

CONTRAINDICATIONS

The MitraClip™ NTR/XTR System is contraindicated in patients with the following conditions:

  • Patients who cannot tolerate procedural anticoagulation or post procedural anti-platelet regimen
  • Active endocarditis of the mitral valve
  • Rheumatic mitral valve disease
  • Evidence of intracardiac, inferior vena cava (IVC) or femoral venous thrombus

WARNINGS

  • DO NOT use MitraClip™ outside of the labeled indication.
  • The MitraClip™ Implant should be implanted with sterile techniques using fluoroscopy and echocardiography (e.g., transesophageal [TEE] and transthoracic [TTE]) in a facility with on-site cardiac surgery and immediate access to a cardiac operating room.
  • Read all instructions carefully.  Failure to follow these instructions, warnings and precautions may lead to device damage, user injury or patient injury. Use universal precautions for biohazards and sharps while handling the MitraClip™ System to avoid user injury.
  • Use of the MitraClip™ should be restricted to those physicians trained to perform invasive endovascular and transseptal procedures and those trained in the proper use of the system.
  • The Clip Delivery System is provided sterile and designed for single use only.  Cleaning, re-sterilization and / or reuse may result in infections, malfunction of the device or other serious injury or death.
  • Use caution when treating patients with hemodynamic instability requiring inotropic support or mechanical heart assistance due to the increased risk of mortality in this patient population. The safety and effectiveness of MitraClip™ in these patients has not been evaluated.

PRECAUTIONS

  • Note the product “Use by” date specified on the package.
  • Inspect all product prior to use. Do not use if the package is open or damaged, or if product is damaged.
  • Prohibitive Risk Primary (or degenerative) Mitral Regurgitation
    • Prohibitive risk is determined by the clinical judgment of a heart team, including a cardiac surgeon experienced in mitral valve surgery and a cardiologist experienced in mitral valve disease, due to the presence of one or more of the following documented surgical risk factors:
    • 30-day STS predicted operative mortality risk score of
      • ≥8% for patients deemed likely to undergo mitral valve replacement or
      • ≥6% for patients deemed likely to undergo mitral valve repair
    • Porcelain aorta or extensively calcified ascending aorta.
    • Frailty (assessed by in-person cardiac surgeon consultation).
