J-Valve Transfemoral Pivotal Study

Официальное название

J-Valve to Treat Aortic Regurgitation Via Transcatheter Therapy

Обзор

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.

Подробное описание

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 7 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.

Вмешательства

• Устройство J-Valve Transfemoral (TF) System
  Treatment includes using the J-Valve Transfemoral (TF) System, a transcatheter aortic valve replacement system that consists of the J-Valve TF Bioprosthesis and the J-Valve TF Delivery Device and Loading Accessories, during transcatheter aortic valve replacement (TAVR). The Edwards 16Fr eSheath+ Introducer Set may be used for the introduction and removal of the J-Valve TF System.
