A Prospective Clinical Study to Evaluate the Safety and Clinical Feasibility of the MitraFix® Transcatheter Mitral Valve System
The goal of this early feasibility clinical trial is to test a new device called the MitraFix® Transcatheter Mitral Valve System. It aims to learn if the device is safe and if it can help adults who have a severe leaky heart valve (mitral regurgitation). This study is for people who are at high risk for traditional open-heart surgery. The main questions it aims to answer are: Is the MitraFix system safe for participants? Can the device be successfully placed in the heart? Does the device help reduce the valve leak and improve daily life? Participants will: Receive the MitraFix valve through a small tube inserted into a vein in the leg. Visit the clinic for heart tests, walking tests, and health checks for up to one year after the procedure.
• Moderate to severe or severe (≥3+) mitral regurgitation.
• Age ≥ 18 years.
• Patients at high risk for traditional open-heart surgery, defined as: STS mortality risk for mitral valve replacement ≥ 8%; OR presence of 2 or more frailty indices; OR presence of 2 or more major organ dysfunctions that cannot be improved post-operatively; OR other comorbidities or factors making them unsuitable for surgery.
• Anatomically suitable for transcatheter MitraFix® system implantation via a transfemoral-transseptal approach as assessed by the investigator; the transfemoral-transseptal access route meets the requirements of the delivery system.
• Able to understand the study purpose, voluntarily participate, sign the informed consent form, and willing to accept relevant examinations and clinical follow-ups.
