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.
