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3-14岁,性别不限; 2)儿童肥厚型心肌病的诊断依据《中国肥厚型心肌病指南2022》: a..对于无HCM家族史且无症状的儿童,当左心室壁最大厚度超过预测正常值的2.5个标准差,即z 值(定义为偏离同年龄儿童正常值的标准差数)>2.5 时可诊断HCM;b.对于有明确HCM家族史或者致病基因检测阳性的儿童,建议采用z 值>2的界值; 3) 静息状态下或激发后左室流出道(LVOT)压差≥50 mmHg; 4) 患儿药物治疗(≥3个月)仍然存在呼吸困难、胸闷、胸痛等症状(NYHA心功能≥II级),或者存在其他与活动相关的症状(如晕厥或晕厥前状态),与左室流出道梗阻相关,影响患儿日常活动和生活质量; 5)若无法评估患儿临床症状,则合并有其他猝死的高危因素(如室间隔厚度z≥6、非持续性室速、重度心肌纤维化、不明原因的晕厥等); 6) 患儿/监护人能够理解临床试验的目的,自愿参加并签署知情同意书。

Inclusion criteria

1) Age 3-14 years old, gender is not limited; 2) The diagnosis of hypertrophic cardiomyopathy in children is based on the Chinese Guidelines for Hypertrophic Cardiomyopathy 2022: a.. In asymptomatic children without a family history of HCM, HCM is diagnosed when the maximum thickness of the left ventricular wall exceeds 2.5 standard deviations from the predicted normal, i.e., z-score (defined as the number of standard deviations from normal for children of the same age) > 2.5; b. For children with a clear family history of HCM or positive test for the causative gene, a cut-off value of z->2 is recommended; 3) Left ventricular outflow tract (LVOT) differential pressure >= 50 mmHg at rest or after excitation; 4) The child still has symptoms such as dyspnea, chest tightness, and chest pain (NYHA cardiac function >= grade II) after drug treatment (>= 3 months), or has other activity-related symptoms (such as syncope or presyncopal state), which is related to left ventricular outflow tract obstruction, affecting the child's daily activities and quality of life; 5) If the clinical symptoms of the child cannot be assessed, there are other high-risk factors for sudden death (such as ventricular septal thickness z>=6, non-sustained ventricular tachycardia, severe myocardial fibrosis, unexplained syncope, etc.); 6) The child/guardian is able to understand the purpose of the clinical trial, voluntarily participate and sign the informed consent form.

排除标准:

1) 有室间隔旋切术手术史; 2) 活动性感染需同期接受抗生素治疗; 3) 合并其他心脏疾病需要外科手术治疗; 4) 心力衰竭(经强化抗心力衰竭治疗,仍有静息性心力衰竭症状,左心室射血分数<40%)); 5) 出血体质以及凝血障碍疾病,或抗凝、抗血小板治疗禁忌; 6) 肾功能不全(血肌酐>2.0mg/dL或177 μmol/l)或接受透析治疗; 7) 近6个月发生一级终点事件(心脏骤停抢救存活或植入埋藏式心脏除颤器(implantable cardioverter-defibrillator, ICD)适当放电)和二级终点事件(满足以下任意一项:因心力衰竭住院、血栓栓塞、终末期HCM); 8) 对麻醉药物过敏,不能耐受全麻手术的患者; 9) 本试验前1个月内参加过任何药物和/或医疗器械临床试验的患者; 10) 研究者判断患者依从性差,无法按照要求完成研究; 11) 研究者判断不适合入组者。

Exclusion criteria:

1. History of ventricular septal atherectomy surgery; 2. Active infection requires concomitant antibiotic therapy; 3. Concomitant other cardiac conditions requiring surgical treatment; 4. heart failure (symptoms of resting heart failure with left ventricular ejection fraction <40%) despite intensive anti-heart failure therapy); 5. hemorrhagic constitution and coagulopathy disorders, or contraindications to anticoagulation and antiplatelet therapy; 6. renal insufficiency (serum creatinine > 2.0 mg/dL or 177 μmol/l) or on dialysis; 7. Occurrence of first-level endpoint events (cardiac arrest rescue survival or implantable cardioverter-defibrillator implantable cardiac defibrillator (ICD) appropriate discharge) and second-level endpoint events (meeting any of the following: hospitalization for heart failure, thromboembolism, end-stage HCM) in the past 6 months; 8. Patients who are allergic to anesthetic drugs and cannot tolerate general anesthesia surgery; 9. Patients who have participated in any clinical trials of drugs and/or medical devices within 1 month prior to this trial; 10. The investigator judged that the patient had poor compliance and was unable to complete the study as required; 11. Those who are judged by the investigator to be unsuitable for enrollment.
