药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄≥18岁,性别不限;
2. 经超声心动图确认的中度以上(MR>2+)的二尖瓣关闭不全;
3. 解剖学上适合二尖瓣修复,且可耐受小切口胸外科手术;
4. NYHA心功能分级II-Ⅳ级;
5. LVESD≤60mm,LVEF≥25%;
6. 本研究的独立专家委员会认为手术禁忌或高危,推荐的参考标准:STS评分≥8的外科瓣膜置换;或STS评分≥6的外科瓣膜修复;或其他危险因素(例如,至少有两个中度至重度的无力指标;潜在的操作失调;至少主要的器官功能障碍,手术后无法改善等);
7. 能够理解试验的目的,自愿参加并签署知情同意书,愿意配合进行临床随访的患者。

Inclusion criteria

1. >= 18 years old, no gender limit;
2. Moderate or above (MR>2+) mitral regurgitation confirmed by echocardiography;
3. Anatomically suitable for mitral valve repair, and can tolerate small incision thoracic surgery;
4. NYHA heart function classification II-IV;
5. LVESD <= 60 mm, LVEF >= 25%;
6. The independent expert committee of this study believes that surgery is contraindicated or high-risk. The recommended reference standard: surgical valve replacement with STS score >= 8; or surgical valve repair with STS score >= 6; or other risk factors (for example, at least two Indicators of moderate to severe weakness; potential operating disorders; at least major organ dysfunction, which cannot be improved after surgery, etc.);
7. Patients who can understand the purpose of the trial, voluntarily participate in and sign an informed consent form, and are willing to cooperate in clinical follow-up.

排除标准:

1. 患有感染性心内膜炎或风湿性二尖瓣疾病者,细菌性心内膜炎活动期;
2. 严重的二尖瓣钙化或二尖瓣狭窄;
3. 超声显示心脏内肿块、血栓或赘生物;
4. 伴有中度以上的主动脉瓣狭窄或返流者;
5. 由特殊的病理机制引起的二尖瓣关闭不全,例如小叶穿孔和小叶裂痕;
6. 肥厚型心肌病伴或不伴梗阻,限制性心肌病,收缩性心包炎或其他导致患者心力衰竭的结构性心脏病,预期扩张型心肌病;
7. 术前30天内有急性心肌梗死病史者;
8. 术前30天内行心脏手术者或同期需要进行心脏手术者,如PCI手术、CAGB手术、心脏移植术、瓣膜手术、CRT心脏再同步治疗、ICD植入手术等者;
9. 3个月内有急性消化性溃疡或上消化道出血史;
10. 严重肝肾功能衰竭者;
11. 活动性感染需要同时进行抗生素治疗;
12. 重度肺动脉高压(肺动脉收缩压>70mm Hg);
13. 血液系统发育不良,包括粒细胞减少症(WBC<3 x 10^9/L),急性贫血(HB <90 g/L),血小板减少症(PLT<50 x 10^9/L),出血性体质和凝血病;
14. 女性患者在怀孕期或哺乳期;
15. 心脏或其他恶性肿瘤的预期寿命<1年;
16. 改良Rankin量表≥4;
17. 正参加其他临床试验未达到主要终点者;
18. 受试者患有可能导致难以评估治疗的疾病(例如癌症、感染、严重的代谢性疾病、精神病等);或研究者评估为不适合该试验的受试者。

Exclusion criteria:

1. Patients with infective endocarditis or rheumatic mitral valve disease, active bacterial endocarditis;
2. Severe mitral valve calcification or mitral valve stenosis;
3. Ultrasound shows a mass, thrombus or vegetation in the heart;
4. Accompanied by moderate or higher aortic valve stenosis or regurgitation;
5. Mitral regurgitation caused by special pathological mechanisms, such as leaflet perforation and leaflet cracks;
6. Hypertrophic cardiomyopathy with or without obstruction, restrictive cardiomyopathy, systolic pericarditis or other structural heart disease that causes heart failure in the patient, expected dilated cardiomyopathy;
7. Those who have a history of acute myocardial infarction within 30 days before surgery;
8. Those who have undergone heart surgery within 30 days before surgery or those who need heart surgery at the same time, such as PCI surgery, CAGB surgery, heart transplantation, valve surgery, CRT heart resynchronization therapy, ICD implant surgery, etc.;
9. A history of acute peptic ulcer or upper gastrointestinal bleeding within 3 months;
10. Severe liver and kidney failure;
11. Active infections require simultaneous antibiotic treatment;
12. Severe pulmonary hypertension (pulmonary artery systolic pressure > 70 mmHg);
13. Blood system dysplasia, including granulocytopenia (WBC < 3 x 10^9/L), acute anemia (HB < 90 g/L), thrombocytopenia (PLT < 50 x 10^9/L), hemorrhagic constitution and blood coagulation sick;
14. Female patients are pregnant or breastfeeding;
15. Life expectancy of heart or other malignant tumors < 1 year;
16. Improved Rankin scale >= 4;
17. Those who are participating in other clinical trials and have not reached the primary endpoint;
18. The subject has a disease that may make it difficult to evaluate and treat (such as cancer, infection, severe metabolic disease, mental illness, etc.); or a subject that the researcher has assessed as unsuitable for the test.
