Description

Summary

The primary objective of this study is to assess the safety and efficacy of the J-Valve Transfemoral (TF) System in patients with symptomatic, severe (grade 3 or 4), native aortic valve regurgitation (AR) and AR-dominant mixed aortic valve disease, who are judged by a multi-disciplinary heart team to be at high risk for open surgical aortic valve replacement (SAVR).

A Cardiac Magnetic Resonance (CMR) sub-study will examine if intervention for AR translates to improved ventricular remodeling, the impact of LV remodeling on clinical outcomes and quality of life, as well as volumetric and myocardial differences between genders.

Official Title

J-Valve to Treat Aortic Regurgitation Via Transcatheter Therapy

Details

This is a prospective, single arm, multi-center, interventional pivotal study that will enroll up to 194 subjects in up to 35 investigational sites, predominantly in the United States and up to 6 in Canada, Europe, and Japan. Of the 194 subjects, the CMR imaging sub-study will include up to 75 subjects with severe AR already confirmed by TTE. Additionally, up to 40 roll-in subjects may be treated to enable clinical experience and exposure to the device while allowing a reasonable learning curve. The subjects will then be followed 5-years post-procedure of the J-Valve TF System.
