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.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

? 患者在注册时必须年满18岁或以上; ? 由独立的超声心动图核心实验室(ECL)使用标准化的超声心动图评估方案进行诊断确定为中重度(3+)或重度(4+)的交界区退行性二尖瓣反流; ? 患者表现显著的心力衰竭临床表现,纽约心脏病学会(NYHA)功能II-IV级,或无症状但有心脏功能障碍的证据,比如左心室收缩末期直径(LVESD)≥ 40mm。 ? 经多学科心脏团队认为具有外科手术高风险或手术禁忌。多学科心脏团队必须包括由专门从事二尖瓣手术的心脏外科医生和对二尖瓣疾病有专长的心衰领域专家 ? ECL和心脏团队确认二尖瓣解剖结构适合经导管二尖瓣缘对缘修复术。 应用这些入选标准旨在标准化参与中心的患者选择,并确保研究结果能够推广到更广泛的适合TEER的交界性二尖瓣反流患者群体。

Inclusion criteria

? Age: Individuals must be 18 years of age or older at the time of enrollment. ? Diagnosis of Commissural DMR: Eligible patients must exhibit symptomatic moderate-to-severe (3+) or severe (4+) commissural DMR, as determined by an independent Echocardiographic Core Laboratory (ECL) using standardized echocardiographic assessments. ? Symptomatology: Patients should present with symptoms consistent with NYHA functional class II, III, or IV, or be asymptomatic with evidence of cardiac dysfunction, including a left ventricular end-systolic dimension (LVESD) of ≥40 mm. ? Surgical Risk Assessment: Participants must be deemed at high or prohibitive surgical risk by a multidisciplinary heart team comprising a cardiac surgeon specialized in mitral valve surgery and a cardiologist with expertise in mitral valve disease. ? Anatomic Suitability for TEER: The presence of interatrial septum and mitral valve anatomy that is amenable to percutaneous edge-to-edge repair as confirmed by the ECL and undiscipline heart team. ? Informed consent:The subject or their guardian voluntarily agrees to comply with all provisions of this clinical trial and to participate in all necessary postoperative follow-ups, and to provide a written informed consent form. The application of these inclusion criteria aims to standardize patient selection across participating centers and ensure that the study's findings are generalizable to the broader population of patients with commissural DMR who are candidates for TEER therapy.
