研究目的:

本研究是一项前瞻性、单臂、单组的多中心临床研究,旨在评估新型解剖分型及手术策略指导下的经导管二尖瓣缘对缘修复术治疗外科手术高风险或禁忌的中度及以上交界区退行性二尖瓣返流患者的安全性和有效性,通过12个月的临床随访,与文献支持的术后效果进行比较。  

Objectives of Study:

This study is a prospective, single-arm, single-arm, multicenter clinical study to evaluate the safety and efficacy of transcatheter mitral margin-to-edge repair guided by novel anatomical typing and surgical strategies in patients with moderate and above junctional degenerative regurgitation who are at high risk or contraindicated for surgery, and compare the postoperative effect with literature-supported clinical follow-up at 12 months.
