5. Study Description

Brief Summary
This study will evaluate the safety of the Cardiovalve Transfemoral Mitral Valve System 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, and long-term clinical outcomes over a follow-up of 2 years.
Detailed Description
The Cardiovalve offers a mitral replacement valve delivered through a transfemoral access and transseptal approach, and is intended to reduce mortality and adverse event rates in selected patients for whom surgical options are not feasible. Innovation: A truly trans femoral, trans venous delivery of the prosthetic mitral valve which minimizes procedural risk. The Cardiovalve Implant features a dual nitinol frame for robust radial strength with decoupling of the atrial flange and ventricular portion which contains 24 grasping legs designed for atraumatic anchoring of the device to the native mitral annulus. Valve leaflets are made of bovine pericardium. The Cardiovalve implant has a very low left ventricle (LV) protrusion footprint thus reducing the risk of LV outflow tract obstruction and/or interference with the LV. The Cardiovalve delivery system (DS) is designed for transfemoral delivery of the Implant with transseptal access to the left atrium. The catheter assembly is used to center the implant relative to the native mitral valve plane and align it with the left ventricual apex-to-base axis. After valve implantation, the delivery system is withdrawn.
