梗阻性肥厚型心肌病(HOCM)是以室间隔非对称性肥厚、左室流出道狭窄,并由此引起梗阻症状为特点的心肌病。降低左室流出道压差是临床治疗有症状HOCM患者的目标,经皮经腔室间隔心肌化学消融术是一种很有前景的介入治疗方法,创伤小、安全性高,并能取得与外科手术同样的疗效。 Obstructive hypertrophic cardiomyopathy (HOCM) is a cardiomyopathy characterized by asymmetric hypertrophy of the interventricular septum, narrowing of the left ventricular outflow tract, and consequent obstruction symptoms. Reducing left ventricular outflow tract pressure is the goal of clinical treatment of patients with symptomatic HOCM. Percutaneous transluminal septal myocardial chemoembolization is a promising interventional therapy with less trauma and higher safety, Surgery the same effect.
