[Comparative evaluation of phonocardiogram and echocardiogram in mitral valve prolapse diagnosis (author's transl)].
In order to determine the correlation between echocardiography (ECHO) and phonocardiography (PHONO) in the evaluation of the Mitral Prolapse Syndrome (PM), 87 subjects with echo or phono criteria of PM were studied using both techniques. The phonocardiographic criteria used for PM diagnosis were the presence of a telesystolic click and/or a telesystolic murmur. The echocardiographic criteria were a telesystolic or holosystolic posterior movement of a mitral leaflet continuously seen through systole or of both mitral leaflets seen in part of systole. In the 63 patients with ECHO indicative of PM, the PHONO was positive in 55 cases (87%). Methoxamin administration, in 5 cases whose basal PHONO was normal, allowed the observation of 3 telesystolic murmurs and 2 clicks. The drug also diminished the number of clicks and increased tfhe telesystolic murmurs. In 79 subjects with PHONO indicative of PM, the ECHO was positive in 57 cases (72%): this technique was of particular value in patients with olosystolic murmur; valuable also to evaluate the diastolic diameter of the left ventricle and the left atrium and other signs having a possible use for a more accurate physiopatologic definition of the PM syndrome.
