Our understanding of hypertrophic cardiomyopathy (HCM) as a disease entity has increased dramatically over the last half century. There has been a concerted effort by several surgical groups to develop operative techniques to relieve left ventricular outflow tract (LVOT) obstruction and alleviate symptoms. This paper traces the development of transaortic septal myectomy, the current gold standard therapy for relief of LVOT obstruction, in symptomatic patients refractory to medical treatment. In addition, we introduce newer methods for myectomy that have expanded the role of surgery in patients with various forms of HCM.
在过去的半个世纪里，我们对肥厚型心肌病（HCM）这一疾病实体的认识有了显著提高。几个外科团队齐心协力开发手术技术，以缓解左心室流出道（LVOT）梗阻并减轻症状。本文追溯了经主动脉间隔心肌切除术的发展历程，这是目前治疗药物难治性有症状患者LVOT梗阻的金标准疗法。此外，我们还介绍了更新的心肌切除方法，这些方法扩大了手术在各种形式HCM患者中的作用。
