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
