Study type | Observational |
Evaluate the hemodynamic and anatomical effect of the commercially available CMCS system within its current indication on a subset of patients with exercise induced mitral regurgitation. This will be primarily evaluated by standard of care exercise testing and echocardiography. The purpose is to evaluate HFrEF CHF patients that may have mild to moderate-severe MR at rest but aggravated upon activity.
