Idiopathic hypertrophic subaortic stenosis (IHSS) is a disease manifested as a spectrum of various clinical and laboratory findings. We present the case of a patient with classical clinical and hemodynamic findings of IHSS who lacked all of the typical echocardiographic features of the disease. The case emphasizes the need for diligent use of bedside physical examination and vasoactive manipulation of systolic murmurs whenever functional left ventricular outflow tract obstruction is suspected, since it can occasionally be missed by echocardiography.
特发性肥厚性主动脉瓣下狭窄（IHSS）是一种表现为各种临床和实验室检查结果的疾病。我们报告一例具有IHSS典型临床和血流动力学表现但缺乏该病所有典型超声心动图特征的患者。该病例强调，当怀疑存在功能性左心室流出道梗阻时，需认真进行床边体格检查并对收缩期杂音进行血管活性药物处理，因为超声心动图偶尔可能会漏诊。
