Fixed subvalvular aortic stenosis is an uncommon cause of left ventricular outflow obstruction which occasionally can be found in association with dynamic muscular obstruction. In the past, the diagnosis of this association has been difficult and relied upon cardiac catheterization and angiography. To our knowledge, no case of this pathology diagnosed by echo and Doppler has previously been reported. We present a case of double subvalvular aortic stenosis in a 35 years old patient which illustrates the feasibility of detection with echo and Doppler of both types of subvalvular aortic obstruction.
固定性瓣下主动脉瓣狭窄是左心室流出道梗阻的一种罕见病因，偶尔可与动态性肌性梗阻并存。过去，这种联合病变的诊断较为困难，依赖于心导管检查和血管造影。据我们所知，此前尚无经超声心动图和多普勒诊断出这种病变的病例报道。我们报告一例35岁患者的双瓣下主动脉瓣狭窄病例，该病例说明了通过超声心动图和多普勒检测两种类型瓣下主动脉梗阻的可行性。
