| Abstract | ed from a previous study from our laboratory."2 widened wall with small changes in transducer angulation or instrument sensitivity. In all but one of our patients, slender valve cusps moved to the periphery of the inner lumen in systole and did not extend to the outer lumen. One patient (Case 5) showed some evidence of thickening of valve cusps and in another thin leaflets were identified, but their motion pattern was not well demonstrated. Slight variation in the direction of the sonic beam during recording produced changes in the width of the aortic root image in two patients. These ranged from 8 to 20 mm in magnitude. In the remaining patients little or no change (less than 5 mm) could be demonstrated in the width of the aortic root during beam angulation. Echocardiographic evidence of aortic regurgitation was present in three patients. This consisted of fine oscillations of the mitral valve in diastole13 together with prominent "a" waves. Three patients showed evidence of large pericardial fluid collections on the echocardiogram. |
