Brief Summary:
To confirm the effectiveness and safety of the Dragonfly transcatheter mitral valve repair system for the treatment of chronic moderate to severe (3+) or severe (4+) functional mitral regurgitation (FMR) who remained clinically symptomatic after adequate treatment.
Detailed Description:
This study is a prospective, multicenter, randomized controlled design. Patients are chronic moderate to severe (3+) or severe (4+) functional mitral regurgitation (FMR) who remained clinically symptomatic after guideline-directed medical treatment. After signing an informed consent form, subjects in the experimental group will undergo the transcatheter mitral valve repair procedure using the DragonFly™ Transcatheter Mitral Valve Clip System . According to the investigator's discretion, all subjects in the treatment group will continue to receive maximally tolerated guideline-directed medical therapy (GDMT). Subjects in the control group will also continue maximally tolerated GDMT as determined by the investigator. After completing the 12-month follow-up, crossover to the treatment group will be permitted.
All subjects were followed up before discharge (excluding the control group), and 30 days, 6 months, 12 months, and 24 months after treatment. Subjects in the experimental group and those who crossed over to the experimental group underwent extended clinical follow-up for 3, 4, and 5 years.
