The paper reviews a 10-year experience with complex ultrasonic diagnosis of membraneous subvalvular aortic stenosis, a rare congenital defect. Fifteen subjects operated on for this abnormality were examined. Profound systolic closure of the aortic cusps, concentrated left ventricular myocardial hypertrophy, linear-shaped echo signals generated by the membrane in the subaortic area, turbulent systolic blood flow in the ascending aorta are the most significant signs for the diagnosis of the membraneous subvalvular aortic stenosis.
本文回顾了对一种罕见先天性缺陷——膜性主动脉瓣下狭窄进行复杂超声诊断的10年经验。对15例因该异常接受手术的患者进行了检查。主动脉瓣叶的深度收缩期关闭、左心室心肌肥厚集中、主动脉瓣下区域膜产生的线性回声信号、升主动脉内的收缩期血流紊乱是诊断膜性主动脉瓣下狭窄的最重要征象。
