Abstract

The present disclosure provides a treatment method for hypertrophic cardiomyopathy applied to an ablation system comprising an ablation needle assembly and an energy generating device coupled to the ablation needle assembly. The treatment method comprises: advancing a distal end of the ablation needle assembly from an outside of a body through an intercostal and a cardiac apex into a ventricular septum; turning on the energy generating device, and using the distal end of the ablation needle assembly to perform radio-frequency ablation or microwave ablation to hypertrophied myocardium within the ventricular septum to make it necrotic and/or atrophic. The present disclosure avoids risk and pain of surgical septal myectomy and extracorporeal circulation in surgical resection, and does not have risk of large-area myocardial infarction caused by alcohol ablation. It is easy to operate and slight trauma to patients.
