To the Editor.—  The article by Forker et al (212:774, 1970) emphasized calcific aortic stenosis with atypical features. Another publication demonstrated the unexpected finding of this lesion in elderly patients who had systolic murmurs.1These lesions are readily diagnosed with the moving slit roentgenokymograph. I have used this kymogram in about 3,600 cases in ten years in correlation with an active cardiopulmonary laboratory and cardiovascular surgical service. This method has been of great value for case finding at unexpected lesions and the preliminary screening of patients before catheter studies. The greatest yield of unexpected lesions has been the finding of a calcified aortic valve. The figure in the right anterior oblique is a typical case.Moving slit roentgenokymography has been almost completely ignored in the United States because the equipment first available in this country was the moving film type. However, kymography of the type illustrated is extraordinarily
