Eligibility | Inclusion Criteria: - Age = 18 years - Severe mitral regurgitation - New York Heart Association (NYHA) Functional Class II, III or ambulatory IV. - Patient is under maximally tolerated GDMT (incl. CRT) for at least 3 months - Multidisciplinary Heart Team consensus that the patient is inoperable or at high-risk for surgical repair/replacement due to significant co-morbid conditions - Multidisciplinary Heart Team consensus that the patient is not a suitable candidate for other approved percutaneous repair therapy due to anatomical or medical conditions - Patient meets the anatomical criteria for HighLife valve sizing as determined by CT and TEE Main Exclusion Criteria: - Mitral stenosis - Rheumatic valve disease - Severe calcifications of the mitral annulus and/or mitral leaflets - Prior surgical or interventional treatment of the mitral valve - Unsuitable anatomy for the transapical access - Unsuitable anatomy of the aorta and ilio-femoral vessels for the transfemoral access - Untreated clinically significant coronary artery disease requiring revascularization - LVEF < 30% - LVEDD > 70mm - Echocardiographic evidence of intracardiac mass, thrombus or vegetation - Hypertrophic Obstructive Cardiomyopathy (HOCM) - Any surgical or interventional procedure (including PCI) done in the past 30 days prior to procedure |

Primary | Freedom of major adverse events | including:
All-cause mortality Myocardial infarction or coronary ischemia requiring PCI or CABG Major stroke Life-threatening bleeding (MVARC scale) Major access and vascular complications Stage 2 or 3 acute kidney injury (includes dialysis) Any valve-related dysfunction, migration, thrombosis, or other complication requiring surgery or repeat intervention Severe hypotension, heart failure or respiratory failure requiring intravenous pressors or invasive or mechanical heart failure treatments such as ultrafiltration or hemodynamic assist devices, including intra-aortic balloon pumps or left ventricular or biventricular assist devices, or prolonged intubation for = 48H |
at 30 days post procedure | |
Primary | Continued intended performance of the HighLife™ bioprosthesis | defined as the reduction of mitral regurgitation (MR) to either optimal (0+ to trace) or acceptable (reduced by at least 1 grade from baseline with no more than 2+ MR) without significant mitral stenosis (post-procedure EOA = 1.5 cm2 with a transmitral gradient < 5mmHg) and with no greater than mild (1+) paravalvular MR (and without associated hemolysis) | at 30 days post procedure | |
Secondary | Technical success | defined as alive patient at exit from procedure room, with all of the following:
Successful access, delivery and retrieval of the HighLife delivery systems Deployment and correct positioning of the HighLife bioprosthesis Freedom of additional emergency surgery or re-intervention related to the device or access procedure |
immediately after procedure |
