简要总结
The Mistral is an investigational device intended for percutaneous trans-catheter repair in high risk for surgery individuals suffering from functional Tricuspid Regurgitation (TR).
The device system is to be used only in accordance with the approved Investigational Plan on subjects who have signed an informed consent form. Device use is limited to the approved study investigators.
详细描述
The study is designed to clinically demonstrate device acute safety and technical performance (Primary Endpoints) along with longer FU device safety and effectiveness evaluation (Secondary Endpoint).
The main objectives of the study are:
- Evaluate the Acute safety of the implanted Mistral device post procedure and at 30 day follow up period.
- Evaluate the long term Safety of the device.
- Demonstrate effectiveness of the Mistral device in reducing TR.
Primary endpoints:
- Safety: Acute safety. Rate of all SAEs including device related SAEs, all caused mortality, stroke, MI, cardiac tamponade, surgery for failed percutaneous repair and non-elective cardiovascular surgery to treat an adverse event. At discharge and 30 days.
- Performance: Mistral Implantation rate of technical success (defined as successful device implantation with grasped chords from at least two leaflets.).
