About this trial
This is an interventional treatment trial for Mitral Regurgitation
Eligibility Criteria
Inclusion Criteria:
- Subject is > 18 years old
- Presence of severe MR as read on a transthoracic echocardiographic study
- Mitral leaflet coaptation surface is sufficient to reduce mitral regurgitation without undue leaflet tension (approximate leaflet to gap ratio of 2:1) based on the judgment of the patient eligibility committee and the operating surgeon
- Degenerative mitral valve disease with mid-segment P2 prolapse
- Patient is able to sign informed consent and able to return for follow-up and is capable of participating in all testing associated with this clinical investigation
Exclusion Criteria:
- Patient is of the age where further growth is expected
- Active endocarditis
- Left ventricular or left atrial appendage thrombus
- Severe mitral annular and/or leaflet calcification
- Cannot tolerate procedural anticoagulation or post-procedure antiplatelet regimen
- Mitral stenosis
- Functional Mitral Valve disease
- Previous mitral valve replacement surgery
- Fragile or thinning apex
- Contraindications to transoesophageal echocardiography (atlantoaxial disease, severe generalized cervical arthritis, upper gastrointestinal bleeding, significant dysphagia and odynophagia, has received extensive radiation to the mediastinum)
- Patient is pregnant or lactating
