| 摘 要： | 应用二维超声心动图(2DE)诊断散在性主动脉瓣下狭窄(DSS)21例。年龄6～63岁(平均24岁)。DSS 分为三型:(1)隔膜型(9例);(2)纤维肌肉环型(9例);(3)纤维肌肉管道型(3例)。DSS 伴室间隔缺损3例,法乐四联症1例。2DE 对诊断DSS 是首选的非侵入性诊断方法。 |

| Abstract: | Two dimensional echocardiography(2DE)was done on 21 patients withdiscrete subaortic stenosis(dss).It revealed the following three anatomicaltypes:(1)diaphragmatic type(9 cases),having two thin fibrous diaphragmsencircling the left ventricular outflow tract(LVOT)below the aortic valve;(2)fibromuscular collar type(9 cases),with a muscular base forming collar-like LVOT obstruction;(3)fibromuscular tunnel type(3 cases),producingdifufse narrowing of the LVOT.(In this group,four cases had concomitantoccurrence of congenital abnormalities,three,ventricular septal defects andone,tetralogy of Fallot)M-mode features of subaortic obstruction are nonspe-cific.2DE is noninvasive diagnostic tool.Since it can reveal precise anatomicdetails of subaortic obstruction,it is useful for the evaluation of LVOT. |
