Abstract

Septal reduction therapies, which include septal myectomy and alcohol septal ablation and so on, are the current treatment strategies for patients with obstructive hypertrophic cardiomyopathy and drug-refractory symptoms. With the deepening of theoretical understanding and the rapid development of interventional therapies, some researchers have tried to perform transcatheter mitral valve edge-to-edge repair to treat high-risk patients with hypertrophic cardiomyopathy, including obstructive and non-obstructive. The reported results are relatively satisfactory, but many urgent problems need to be solved, such as the lack of data on animal experiments and large cohort studies, and the unknown medium- and long-term outcomes. However, transcatheter mitral valve edge-to-edge repair brings new ideas for the diagnosis and treatment of patients with hypertrophic cardiomyopathy. On one hand, it can be used as a monotherapy, on the other hand, it can be combined with novel molecular targeted drug therapy or emerging minimally invasive surgical procedures targeting hypertrophic ventricular septum, which deserves our further attention and exploratory research.

对于药物治疗无效的梗阻性肥厚型心肌病患者,目前主要采用室间隔减容治疗,如室间隔心肌切除术、室间隔乙醇消融术等。随着对理论知识认识的加深和介入治疗的飞速发展,先后有学者尝试应用经导管二尖瓣缘对缘修复治疗高危肥厚型心肌病患者,在梗阻性和非梗阻性患者中均取得满意的治疗效果,但亦存在不少亟待解决的问题,如缺乏动物试验数据及大型队列研究数据、中远期治疗效果未知等。经导管二尖瓣缘对缘修复为肥厚型心肌病患者的诊疗带来了新的思路,一方面或可作为单独疗法,另一方面或可联合新型分子靶向药物或以肥厚室间隔为靶点的新兴微创治疗方式进行治疗,值得我们进一步关注与探索。.
