title: [Functional aortic systolic murmurs in the elderly].
abstract: The authors report a clinical and phonocardiographic study of functional aortic systolic murmurs in 26 elderly patients, in 19 of which the lesion was confirmed pathologically. Systolic murmurs radiating across the chest in elderly have the same clinical characteristics as aortic stenosis from which they may, however, be distinguished owing to the: absence of a thrill during systole. The brief duration and the proto-meso-systolic position of the murmur with early inscription of maximal oscillations on the phonocardiogram. Conversion of the second aortic sound. Almost constant absence of a diastolic murmur. Normal carotid arteriogram, including normal ejection time after correction and time of half rise. "Innocent" systolic murmurs are due to calcification of the aortic valve without stenosis, and/or dilatation of the ascending aorta. There is no systolic pressure gradient between the left ventricle and the aorta during cardiac catheterisation. No lesions were found in the mitral valve suggesting mitral incompetence, therefore, we consider the term mitro-aortic murmur used by Huchard should be dropped; Radiation of the murmur from the apex of the heart up into the neck may be explained by the simultaneous occurrence of anatomical changes due to age and/or hypertension and by the vibratory nature of the murmurs which become propagated above and below their origin, as shown by the intracardiac recordings.
