Until now, mitral valve surgery has been the only option that reliably reduces mitral regurgitation (MR). For your select high-surgical-risk degenerative MR (DMR) patients (MR ≥ 3+), MitraClip® therapy can offer a solution.
Remember, it’s important to diagnose MR early, as patients who go untreated have a greater risk of developing heart failure. Use the tools below to help identify all appropriate patients in your

Per the 2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease (Class I recommendation), complex patients like those with severe, symptomatic DMR should be evaluated by a Heart Valve Center of Excellence, such as a TMVr Center.3
Optimal candidates for MitraClip® therapy should meet the following criteria1
Significant DMR (MR ≥ 3+)
High risk for surgery due to factors that may include age, frailty, or severe comorbidities such as liver disease and pulmonary hypertension
Diagnosis of symptomatic severe DMR is based on multiple parameters3
- Severe mitral valve prolapse with loss of coaptation or flail leaflet
- Rheumatic valve changes with leaflet restriction and loss of central coaptation†
- Prior infective endocarditis
- Thickening of leaflets with radiation heart disease
- Central jet MR > 40% left atrium (LA) or holosystolic eccentric jet MR
- Vena contracta ≥ 0.7 cm
- Regurgitant volume ≥ 60 mL
- Regurgitant fraction ≥ 50%
- Effective regurgitant orifice ≥ 0.40 cm2
- Angiographic grade 3-4+
- Moderate or severe LA enlargement
- Left ventricular enlargement
- Pulmonary hypertension present
- Decreased exercise tolerance
- Exertional dyspnea
*Several valve hemodynamic criteria are provided for assessment of MR severity, but not all criteria for each category will be present in each patient. Categorization of MR severity as mild, moderate, or severe depends on data quality and integration of these parameters in conjunction with other clinical evidence.
†Rheumatic mitral valve disease is a contraindication for MitraClip® therapy.
MitraClip® NT Clip Delivery System
INDICATION FOR USE
The MitraClip® NT Clip Delivery 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® NT Clip Delivery System is contraindicated in DMR 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
- DO NOT use MitraClip® NT outside of the labeled indication. Treatment of non-prohibitive risk DMR patients should be conducted in accordance with standard hospital practices for surgical repair and replacement.
- MitraClip® NT is intended to reduce mitral regurgitation. The MitraClip® NT procedure is recommended to be performed when an experienced heart team has determined that reduction of MR to ≤2+ is reasonably expected following the MitraClip® NT. If MR reduction to ≤2+ is not achieved, the benefits of reduced symptoms and hospitalizations, improved quality of life, and reverse LV remodeling expected from MitraClip® NT may not occur.
- The MitraClip® NT Device 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® NT System to avoid user injury.
- Use of the MitraClip® NT 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.
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)
- Hostile chest
- Severe liver disease / cirrhosis (MELD Score >12)
- Severe pulmonary hypertension (systolic pulmonary artery pressure >2/3 systemic pressure)
Unusual extenuating circumstance, such as right ventricular dysfunction with severe tricuspid regurgitation, chemotherapy for malignancy, major bleeding diathesis, immobility, AIDS, severe dementia, high risk of aspiration, internal mammary artery (IMA) at high risk of injury, etc.
- Evaluable data regarding safety or effectiveness is not available for prohibitive risk DMR patients with an LVEF <20% or an LVESD >60mm. MitraClip® NT should be used only when criteria for clip suitability for DMR have been met.
- The major clinical benefits of MitraClip® NT are reduction of MR to ≤2+ resulting in reduced hospitalizations, improved quality of life, reverse LV remodeling and symptomatic relief in patients who have no other therapeutic option. No mortality benefit following MitraClip® NT therapy has been demonstrated.
- The heart team should include a cardiac surgeon experienced in mitral valve surgery and a cardiologist experienced in mitral valve disease and may also include appropriate physicians to assess the adequacy of heart failure treatment and valvular anatomy.
- The heart team may determine an in-person surgical consult is needed to complete the assessment of prohibitive risk. The experienced mitral valve surgeon and heart team should take into account the outcome of this surgical consult when making the final determination of patient risk status.
- For reasonable assurance of device effectiveness, pre-procedural evaluation of the mitral valve and underlying pathologic anatomy and procedural echocardiographic assessment are essential.
- Note the “Use by” date specified on the package.
- Inspect all product prior to use. DO NOT use if the package is opened or damaged, or if product is damaged.
