研究目的:

评估在标准 Morrow 手术基础上,增加瓣下肌小梁切除松解术,对 HCM 合并舒张功能障碍患者左心室舒张功能的干预价值。  

Objectives of Study:

To evaluate the therapeutic value of supplementing the standard Morrow procedure with the resection and release of subvalvular trabeculae on left ventricular diastolic function in patients with hypertrophic cardiomyopathy (HCM) and concomitant diastolic dysfunction.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄≥18周岁,具有完全民事行为能力,能理解并签署知情同意书; (2)被诊断为肥厚型心肌病(HCM),具有明确的左心室流出道梗阻表现; (3)心脏超声和/或心脏磁共振提示舒张功能障碍; (4)未接受过 Morrow 手术或其他影响左室小梁结构的干预治疗; (5)临床评估后被建议接受药物保守治疗或外科手术治疗,并愿意按相应治疗方式进行随访; (6)愿意遵守研究流程,配合术前评估、治疗及术后/随访期检查。

Inclusion criteria

(1) Age >= 18 years, possessing full civil capacity, and able to understand and sign the informed consent form; (2) Diagnosed with hypertrophic cardiomyopathy (HCM) and presenting with clear evidence of left ventricular outflow tract (LVOT) obstruction; (3) Diastolic dysfunction indicated by echocardiography and/or cardiac magnetic resonance (CMR) imaging; (4) No prior history of the Morrow procedure or any other interventional therapy that alters the left ventricular trabecular structure; (5) Deemed suitable for and recommended to receive either conservative medical therapy or surgical treatment following clinical evaluation, and willing to undergo follow-up according to the assigned treatment plan; (6) Willing to comply with the study protocol, including cooperating with pre-operative assessments, the treatment itself, and post-operative/follow-up examinations.

排除标准:

存在以下情况之一,将无法参加本项研究: (1)存在严重的合并疾病(如活动性恶性肿瘤、终末期肝肾功能不全等); (2)研究期间或既往已接受其他可能影响心脏结构和功能的干预治疗(如酒精消融、起搏器植入等); (3)妊娠或哺乳期女性,或计划在研究期间怀孕者; (4)研究人员认为存在影响研究结果判断的其他情况。

Exclusion criteria:

Patients presenting with any of the following conditions will be excluded from participation in this study: (1) Presence of severe concomitant diseases (e.g., active malignant tumor, end-stage hepatic or renal dysfunction, etc.); (2) Having previously undergone or scheduled to receive, during the study period, other interventional therapies that may affect cardiac structure and function (e.g., alcohol septal ablation, pacemaker implantation, etc.); (3) Pregnancy or lactation, or planning to become pregnant during the study period; (4) Any other condition deemed by the investigators to potentially compromise the interpretation of the study results.
