研究目的:

临床研究的主要目的是评估DragonFlyTM经导管二尖瓣瓣膜夹系统在经药物治疗后仍有症状,且接受三尖瓣外科手术的预计死亡风险为中等及以上或不适合外科开胸手术的重度三尖瓣反流患者中的安全性和有效性。同时对产品的性能及可靠性进行临床评价,从而使临床医生熟悉手术器械和手术方式  

Objectives of Study:

The main purpose of the clinical study is to evaluate safety and effectiveness using the DragonFlyTM transcatheter mitral valve clamp system in patients who are still symptomatic after medical treatment, and the estimated mortality risk of undergoing tricuspid valve surgery is moderate or above or the severe third who is not suitable for surgical thoracotomy. At the same time, performing clinical evaluation of performance and reliability, so that clinicians are familiar with the interventional method.
