纳入标准: |
1)患者年龄≥18岁; 2)具有临床症状且超声心动图证实为中重度(3+)或重度(4+)慢性二尖瓣反流(MR)患者(包括DMR和FMR1); 3)NYHA心功能分级II-IV级; 4)左心室射血分数LVEF≥20%; 5)解剖上适合进行二尖瓣瓣膜修复且经评估适合使用本研究器械; 6)若患者为DMR则需满足: A.腱索断裂导致脱垂; B.由当地临床试验机构心脏团队判断为外科手术高危,建议参考标准为:外科手术瓣膜置换STS评分≥8分,或外科瓣膜修复STS评分≥6分,或者存在其他外科高危因素(如有≥2个中到重度的虚弱指标或存在可能的手术操作障碍或存在≥2个在术后不能改善的主要器官功能障碍或由心脏团队判断存在的其他外科高危因素); 若患者为FMR则需满足: A.缺血或非缺血性心肌病引起的症状性功能性二尖瓣反流FMR(≥3+); B.左心室收缩末内径(LVESD)≤70mm; C.过去12个月内至少有过一次因心力衰竭住院治疗,和/或受试者BNP>150pg/ml,或经校正2的NT-proBNP>600pg/ml; D.接受包括指南指导用药(Guideline Directed Medical Therapy ,GDMT)治疗在内的最佳治疗稳定后获得或至少30天后获得以下情况:GDMT剂量增加大于100%或减少大于50%;冠状动脉血运重建和或植入心脏再同步化治疗装置(CRT或CRT-D),或对植入的CRT或CRT-D进行重新程控,使双心室起搏增加(从<92%到≥92%)。 E.GDMT后依然存在中重度(3+)以上反流; 7)受试者已被告知本研究的性质,能够理解临床试验的目的,自愿参加并签署知情同意书。 注1: FMR要求存在整体或局部左心室室壁运动异常,且被认为是MR的主要原因。如果存在瓣叶脱垂或其他退行性MR的证据,即使存在整体或局部左室收缩功能障碍,受试者也不符合条件。 注2:校正是指当患者体重指数BMI高于20kg/㎡时,BMI每增加lkg/㎡,NT-proBNP的界值降低4%。 |

Inclusion criteria |
1)Patients ≥18 years of age; 2)Patients with clinical symptoms and echocardiographically confirmed moderate-severe (3+) or severe (4+) chronic mitral regurgitation (MR) (including DMR and FMR1); 3)NYHA cardiac function class II-IV; 4)Left ventricular ejection fraction LVEF ≥ 20%; 5) Anatomically suitable for mitral valve valve repair and evaluated for suitability for use of the study device; 6) If the patient is a DMR it is required to fulfill: A. tendon cable rupture resulting in prolapse; B. surgical high risk as judged by the local clinical trial site cardiac team, with the recommended reference criteria being a surgical valve replacement STS score of ≥8 or a surgical valve repair STS score of ≥6 or the presence of other surgical high risk factors (e.g., the presence of ≥2 indicators of moderate-to-severe weakness or the presence of possible impaired surgical maneuvers or the presence of ≥2 major organ dysfunction that does not improve in the postoperative period or other surgical high risk factors judged by the cardiac team to determine the presence of other surgical risk factors); To be met if the patient is FMR: A. Symptomatic functional mitral regurgitation FMR (≥3+) due to ischemia or non-ischemic cardiomyopathy; B. left ventricular end-systolic internal diameter (LVESD) ≤70 mm; C. at least one hospitalization for heart failure in the past 12 months and/or subject has a BNP >150 pg/ml,or corrected2 NT-proBNP >600 pg/ml; D. Obtained after stabilization on optimal therapy including Guideline Directed Medical Therapy (GDMT) therapy or after at least 30 days of the following: GDMT dose increase greater than 100% or decrease greater than 50%; coronary revascularization and or implantation of a cardiac resynchronization therapy device (CRT or CRT-D), or reprogramming of an implanted CRT or CRT-D to increase biventricular pacing (from <92% to ≥92%). E. Moderate-to-severe (3+) or greater regurgitation remains after GDMT; 7) Subjects have been informed of the nature of the study, are able to understand the purpose of the clinical trial, and voluntarily participate and sign an informed consent form. Note 1: FMR requires the presence of global or localized LV wall motion abnormalities that are considered to be the primary cause of MR. Subjects are not eligible if leaflet prolapse or other evidence of degenerative MR is present, even if there is overall or localized LV systolic dysfunction. Note 2: Correction is when the patient's body mass index BMI is above 20 kg/m2, and for every lkg/m2 increase in BMI, the NT-proBNP cutoff is reduced by 4%. |
