Early Feasibility Study of the AccuCinch® Ventricular Restoration System in Patients With Prior Mitral Valve Intervention (PMVI) and Recurrent Mitral Regurgitation

Device name changed from AccuCinch® Ventricular Repair System to AccuCinch® Ventricular Restoration System, FDA Approval Date August 14, 2020.

Inclusion criteria

• Study patient is at least 18-years old
• Severity of FMR: ≥ Moderate (i.e., ≥2+, according to Stone et al Clinical Trial Design Principles and Endpoint Definitions for Transcatheter Mitral Valve Repair and Replacement: Part 1: Clinical Trial Design Principles. A Consensus Document from the Mitral Valve Academic Research Consortium1; and 2003 ASE Guidelines for grading mitral regurgitation2)
• Patient has had a prior surgical or percutaneous mitral repair procedure >3 months prior to enrollment
• LV Ejection Fraction: ≥20 to ≤40%
• Symptom Status: NYHA II-IV (i.e., ambulatory)
• Prescribed appropriate guideline-directed medical therapy for heart failure for at least 3 months with stable doses of diuretics, beta-blockers and Angiotensin converting enzyme inhibitor (ACEi) or Angiotensin II Receptor Blockers (ARB) for 1 month (with stable defined as no greater than 100% increase of 50% decrease in medication doses). Treatment shall include CRT and/or ICD when indicated by guidelines.
• Able and willing to complete all qualifying diagnostic and functional tests and agrees to comply with study follow-up schedule

Exclusion criteria

• Patients with significant organic mitral valve pathology (e.g. myxomatous degeneration, mitral valve prolapse or flail leaflets)
• Myocardial infarction or any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 3 months
• Prior surgical, transcatheter, or percutaneous mitral valve replacement
• Untreated clinically significant coronary artery disease (CAD) requiring revascularization
• Hemodynamic instability: Hypotension (systolic pressure <90 mmHg) or requirement for inotropic support or mechanical hemodynamic support
• Any planned cardiac surgery or interventions within the next 6 months (including right heart procedures)
• NYHA class IV (i.e., non-ambulatory)
• Fixed pulmonary artery systolic pressure >70 mmHg
• Severe tricuspid regurgitation
• History of stroke within the prior 3 months or any prior stroke with Modified Rankin Scale ≥ 4 disability
• Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or any other structural heart disease causing heart failure other than dilated cardiomyopathy of either ischemic or non-ischemic etiology
• Anatomical pathology or constraints preventing appropriate access/implant of the AccuCinch® Ventricular Repair System (e.g., femoral arteries will not support a 20F system)
• Renal insufficiency (i.e., eGFR of <30ml/min/1.73m2; Stage 4 or 5 CKD)
• Moderate or severe aortic valve stenosis or regurgitation or aortic valve prosthesis
• Fluoroscopic or echocardiographic evidence of severe aortic arch calcification, mobile aortic atheroma, intracardiac mass, thrombus or vegetation
• Active bacterial endocarditis
• Subjects in whom anticoagulation or antiplatelet therapy is contraindicated
• Known allergy to nitinol, polyester, or polyethylene
• Any prior true anaphylactic reaction to contrast agents; defined as known anaphylactoid or other non-anaphylactic allergic reactions to contrast agents that cannot be adequately pre-medicated prior to the index procedure.
• Life expectancy < 1 year due to non-cardiac conditions
• Currently participating in another interventional investigational study
• Implant or revision of any rhythm management device (CRT or CRT-D) prior 3 months or implantable cardioverter defibrillator within the prior 1 month
• Subjects on high dose steroids or immunosuppressant therapy
• Female subjects who are pregnant, of child bearing potential without a documented birth control method, or lactating
