Study Description
Brief Summary

Detailed Description
The primary objectives of this study are to evaluate the safety and performance of the AccuCinch Ventricular Repair System for the treatment of heart failure and functional mitral regurgitation in symptomatic adult patients with or without functional mitral regurgitation (FMR) and left ventricular remodeling due to dilated cardiomyopathy (ischemic or non-ischemic etiology), who remain symptomatic despite optimized medical therapy.
Subjects with FMR must present with at least moderate FMR, a reduced ejection fraction (≤40%) and high operative risk as assessed by the Heart Team. The Heart Team may utilize established risk scores (STS, Euro-Score II) in conjunction with comorbidities as recommended by MVARC (frailty index; major organ system compromise not to be improved postoperatively; procedure specific impediments).
Subjects without FMR must present a markedly dilated left ventricle with LVEDD ≥ 55 mm and reduced ejection fraction (≤40%). These patients are not potential candidates for "conventional intervention", because their mitral valve is not in need of repair or replacement. Therefore, AccuCinch represents the sole treatment option for these patients, who are not selected on the basis of high surgical risk.

Outcome Measures
Primary Outcome Measures
- Safety outcome: 30-day major adverse events (MAEs) [30-day]
Major adverse event (MAE) where MAE is a composite of the following device- or procedure-related events: A. All-cause mortality B. Stroke C. Life-threatening bleeding (MVARC scale) D. Major vascular complications E. Major cardiac structural complications F. Myocardial infarction or coronary ischemia requiring PCI or CABG G. Stage 2 or 3 acute kidney injury (includes new dialysis) H. Severe hypotension, worsening of 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 >48 h. I. Emergency surgery or re-intervention related to the device or access procedure
Secondary Outcome Measures
- Technical success: Successful access, delivery, and retrieval of AccuCinch System components, successful deployment of the AccuCinch implant without need for unplanned or emergency surgery or re-intervention [30-day]
Successful access, delivery, and retrieval of all AccuCinch catheters. Deployment and correct positioning of the intended AccuCinch implant, and no need for additional unplanned or emergency surgery or re-intervention related to the device or access procedure measured upon completion of the procedure.
- Structural performance: Assessment of device integrity [30-day]
No migration, embolization, detachment, fracture, hemolysis, thrombosis or endocarditis; and no para-device complications (erosion, effusion requiring surgery or drainage or producing tamponade, damage to the MV apparatus)
- Clinical outcome: Freedom from re-hospitalizations or re-interventions for the underlying condition [30-day]
Freedom from re-hospitalizations or re-interventions for the underlying condition
- Clinical outcome: Improvement in NYHA functional class [30-day]
Improvement in NYHA functional class when compared to baseline assessment
- Clinical outcome: Improvement in six-minute walk test [30-day]
Improvement in six-minute walk test (6MWT) when compared to baseline assessment
- Clinical outcome: Improvement in Kansas City Cardiomyopathy Questionnaire (KCCQ) Quality of Life (QoL) [30-day]
Improvement in Kansas City Cardiomyopathy Questionnaire (KCCQ) Quality of Life (QoL) when compared to baseline
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Age ≥ 18 years
-
Subjects who present with heart failure with or without functional mitral regurgitation due to dilated cardiomyopathy of ischemic or non-ischemic etiology
-
For subjects with FMR, severity of FMR: ≥ Moderate 2+
-
For subjects without FMR, LVEDD ≥ 55 mm
-
Ejection Fraction: ≥20 to ≤40%
-
Symptom Status: NYHA II-IVa
-
Patients to be considered for the present study will be required to have received all appropriate guidelines-recommended therapies for at least 3 months prior to the enrollment with stable doses of drugs for at least 1 month.
-
Surgical risk:
-
For patients with FMR only: the Heart Team must assess as high-risk and may utilize risk score or comorbidities to demonstrate high risk features. High risk for mitral valve surgery is defined utilizing established risk scores (STS, Euro-Score II) in conjunction with comorbidities as recommended by MVARC (frailty index; major organ system compromise not to be improved postoperatively; procedure specific impediments) (MVARC Part 1)
-
For all patients: Subject is eligible for cardiac surgery (namely, the patient is in a condition that allows a potential conversion to open surgery in case of procedural complications). This criterion adds a safety level for the patients
-
Completion of all qualifying diagnostic and functional tests and agrees to comply with study follow-up schedule
-
Patients required to have an ICD are required to have ICD implant at least 1 month prior to enrollment
Exclusion Criteria:
-
Life expectancy <1 yr due to noncardiac conditions
-
NYHA functional class IVb or ACC/AHA stage D heart failure
-
Hypotension (systolic pressure <90 mm Hg) or requirement for inotropic support or mechanical hemodynamic support
-
Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or any other structural heart disease causing heart failure other than dilated cardiomyopathy of either ischemic or nonischemic etiology
-
Fixed pulmonary artery systolic pressure >70 mm Hg
-
Physical evidence of right-sided congestive heart failure with echocardiographic evidence of moderate or severe right ventricular dysfunction
-
Mitral valve anatomy which may preclude proper device treatment
-
Mitral valve area <4.0 cm2 (if new device therapy may further decrease the mitral orifice area)
-

-

-
Need for emergent or urgent surgery for any reason or any planned cardiac surgery within the next 12 months
-

-

-
Myocardial infarction ≤ 30 days
-
Any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 30 days
-
Tricuspid valve disease requiring surgery or severe tricuspid regurgitation (per ASE guidelines; core lab assessment)
-
Aortic valve disease requiring surgery
-
Moderate or severe aortic valve stenosis or regurgitation
-
Aortic valve prosthesis
-
Fluoroscopic or echocardiographic evidence of severe aortic arch calcification, mobile aortic atheroma, intracardiac mass, thrombus, or vegetation
-
Need for any cardiovascular surgery (other than for MV disease)
-
Active endocarditis
-
Anatomical pathology/constraints preventing appropriate access/implant of the AccuCinch System (e.g., femoral arteries will not support an 20F system)
-
Known allergy to nickel, polyester, or polyethylene
-

-
Subjects in whom anticoagulation or antiplatelet therapy is contraindicated
-
