[Phonomechanocardiographic diagnosis of the apparently "silent" mitral valve prolapse syndrome (author's transl)].
Five cases with angiocardiographically diagnosed posterior mitral valve prolapse and without ausculatotory findings of midsystolic click or late systolic murmur were studied with phonocardiographic technique employing pharmacological tests and postural changes. A midsystolic click was thus obtained. Isoprenaline was the must helpful drug to achieve it. The accompanying electrocardiographic and coronarographic features of this syndrome are described and discussed.
