About
The study will test the safety and performance of the Cardiovalve transfemoral mitral valve replacement system in treating patients with severe mitral regurgitation who are at high risk for open chest surgery. The system is comprised of comprised of: 1) an Implant; 2) a Delivery System (DS); and 3) Accessories that are required for the implantation procedure. the procedure is performed under general anesthesia.
Full description
The study will test the safety and performance of the Cardiovalve transfemoral mitral valve replacement system in treating patients with severe mitral regurgitation who are at high risk for open chest surgery. The system is comprised of comprised of: 1) an Implant; 2) a Delivery System (DS); and 3) Accessories that are required for the implantation procedure. The implant procedure is performed under general anesthesia, and the participants will be followed-up at discharge, 1- 3-, 6-, 12- and 24-months post-procedure, in order to check the system functionality and effect on their cardiology status.
