[Dynamic phonocardiography in the study of mitral valve prolapse. Our experience].

Abstract

The purpose of this paper is to check the usefulness of dynamic phonocardiography for mitral valve prolapse (MVP) diagnosis, especially in apparently silent cases, or with late-systolic click. In fact, possible MVP or mitral valve regurgitation can be shown. 148 patients (58 males, 90 females) have been examined by basal and dynamic phonocardiography and M-echocardiography. Patients were recruited for routine medical examination or during investigations for other causes or to explain evocative MVP troubles. Provocative tests by amyl nitrite, isoproterenol and methoxamine registered a late-systolic click in 17 normal cases and a late-systolic murmur in 22. M-echo demonstrated MVP in 142 cases (96%), with a slight prevalence of late-systolic MVP; tricuspid valve prolapse coexisted in 8 cases and aortic regurgitation in 12. Today echocardiography is the most important examination, but all our data point to the usefulness of dynamic phonocardiography for MVP diagnosis: in our opinion, the integration of both techniques represents the most correct approach.
