Early Feasibility Evaluation of the AccuCinch® Ventricular Restoration System in Patients With Heart Failure and Reduced Ejection Fraction

Korábbi kezelés

• Prior surgical, transcatheter, or percutaneous mitral valve intervention
• Anatomical pathology or constraints preventing appropriate access/implant of the AccuCinch® Ventricular Repair System (e.g., femoral arteries will not support a 20F system)
• History of any stroke within the prior 3 months or Modified Rankin Scale ≥ 4 disability from any prior stroke
• Subjects in whom anticoagulation or antiplatelet therapy is contraindicated
• 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.
• 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

Más betegség

• Myocardial infarction or any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 3 months
• Untreated clinically significant coronary artery disease (CAD) requiring revascularization
• Any planned cardiac surgery or interventions within the next 6 months (including right heart procedures)
• 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
• Known allergy to nitinol, polyester, or polyethylene
• Life expectancy < 1 year due to non-cardiac conditions

Laborértékek

• Renal insufficiency (i.e., eGFR of <30ml/min/1.73m2; Stage 4 or 5 CKD)

Egyéb

• Mitral regurgitation grade 3 (moderate-severe) or more
• Hemodynamic instability: Hypotension (systolic pressure <90 mmHg) or requirement for inotropic support or mechanical hemodynamic support
• NYHA class IV (i.e., non-ambulatory)
• Significant RV dysfunction (TAPSE < 14)
• Severe tricuspid regurgitation
• 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
• Currently participating in another interventional investigational study
• Female subjects who are pregnant, of child bearing potential without a documented birth control method, or lactating

• Study patient is at least 18-years old
• Ejection Fraction: ≥20 and ≤40%
• LV end-diastolic diameter ≥55 mm
• Symptom Status: NYHA III-IV (i.e., ambulatory)
• Treatment and compliance with optimal guideline directed medical and device-based therapies for heart failure (unless contraindicated or intolerant) for at least 3 months and stable doses for 1 month with stable defined as no more than 100% increase or 50% decrease of total daily doses.
• Patients with left bundle branch block pattern and QRS duration >150ms are required to have a CRT device for at least 3 months
• Patients required to have an ICD are required to have ICD implant at least 1 month prior to enrollment
• Able and willing to complete all qualifying diagnostic and functional tests and agrees to comply with study follow-up schedule
