Cardiovalve Transfemoral System - FIM Study

Официальное название

Cardiovalve Transfemoral Mitral Valve System in Patients at High Surgical Risk With Severe Mitral Regurgitation

Обзор

The Cardiovalve system is a replacement valve delivered through a transfemoral access and transseptal approach and is intended for symptomatic patients with Mitral regurgitation for whom surgical options are not feasible.

Подробное описание

The Cardiovalve system is a replacement valve delivered through a transfemoral access and transseptal approach and is intended for symptomatic patients with Mitral regurgitation for whom surgical options are not feasible.

The purpose of this study is to evaluate the safety of the CardiovalveSystem with its associated procedure, and observe the device performance in reducing mitral regurgitation Data collected in this clinical study will include 30-day safety and performance of the device and delivery system, and long-term clinical outcomes over a follow-up of 2 years.
