The CorCinch - Functional Mitral Valve Regurgitation (FMR) Study

Device name changed from AccuCinch® Ventricular Repair System to AccuCinch® Ventricular Restoration System, FDA Approval Date 08Aug2020

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 Consortium11; and 2003 ASE Guidelines for grading mitral regurgitation10)
• Ejection Fraction: ≥20 to ≤60%
• Symptom Status: NYHA II-IV (i.e., ambulatory)
• Treatment and compliance with optimal guideline directed medical therapy for heart failure for at least 1 month
• Surgical risk: Subject is eligible for cardiac surgery (specific risk score or comorbidities should demonstrate high risk features, as determined by the Heart Team)
• Completion of 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 30 days
• Prior surgical, transcatheter, or percutaneous mitral valve intervention
• 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) or American College of Cardiology (ACC)/American Heart Association (AHA) Stage D heart failure
• Fixed pulmonary artery systolic pressure >70 mmHg
• Severe tricuspid regurgitation (per ASE guidelines and graded by the Echo Core Lab)
• 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/constraints preventing appropriate access/implant of the AccuCinch® Ventricular Restoration 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
