简要总结
This is a single-arm, multi-center, open-label controlled study that will assess the safety and performance of the Accucinch System to induce left ventricular reverse remodeling and reduce the severity of functional mitral regurgitation in symptomatic adult patients with mitral regurgitation and left ventricular remodeling due to dilated cardiomyopathy (ischemic or non-ischemic etiology), who are of high operative risk.

研究组 & 干预措施
Accucinch Implant
Experimental
Accucinch Implant procedure is completed
干预措施: Accucinch Implant (Device)
结局指标
主要结局
The additive reduction in the mitral annular axial dimensions (anteroposterior plus commissure-to-commissure axes) measured via echocardiography, paired by subject
时间窗: 6 months
The differences between baseline and 6 months in the sum of the two annulus measures will be calculated for each subject and the mean change tested via the paired t-test.
次要结局
- Device Success: Percentage of patients in whom all pre-specified device performance endpoints are met but no pre-specified device complications are met.(30 Days, 6 months, 12 months, and 2 years)
- Procedural Safety: Incidence rate of the occurrence of the individual pre-specified safety events that occur within 30 days of the index procedure(30 days after the index procedure)
- Long Term Safety: Incidence rate of the occurrence of the individual pre-specified safety events at 6 months, 1 year, and 2 years.(6 months, 1 year, 2 years post index procedure)
