Subaortic stenosis (SAS) is a congenital heart disease, and its association with hypertrophic cardiomyopathy is very rare and clinically underappreciated. We report here a case of a 45-year-old female who was admitted to our hospital with chest tightness and shortness of breath. Both transthoracic and transesophageal echocardiography revealed asymmetric left ventricular hypertrophy and a membrane-like echo below the level of the aortic valve. This patient was diagnosed with membranous SAS with hypertrophic cardiomyopathy. Screening of her immediate family members revealed that her son also had hypertrophic cardiomyopathy. The patient chose conservative treatments and has been closely followed-up after discharge.
主动脉瓣下狭窄（SAS）是一种先天性心脏病，其与肥厚型心肌病的关联非常罕见，临床上也未得到充分认识。我们在此报告一例45岁女性患者，她因胸闷和气短入院。经胸和经食管超声心动图均显示左心室不对称肥厚以及主动脉瓣水平以下的膜样回声。该患者被诊断为膜性SAS合并肥厚型心肌病。对其直系亲属进行筛查发现，她的儿子也患有肥厚型心肌病。患者选择了保守治疗，出院后一直接受密切随访。
