He S - - 1997
BACKGROUND AND AIMS OF THE STUDY: There is growing evidence for mitral leaflet elongation in patients with hypertrophic cardiomyopathy. Such elongation could predispose to systolic anterior motion (SAM) of the mitral valve by increasing leaflet mobility and providing a geometry that promotes this condition. METHODS: To test this postulate, five ...

The incidence of and the Doppler color-flow echocardiographic characteristics of aortic valve prolapse with nonrheumatic aortic regurgitation were examined. Aortic valve prolapse was observed in 21 of 243 patients (15 men and 6 women) with aortic regurgitation as detected by Doppler color-flow echocardiography (rheumatic, 112; nonrheumatic, 131) in 1247 consecutive ...
Barlow J B - - 1992
Three decades after it was demonstrated that nonejection systolic clicks and late systolic murmurs have a mitral valve origin and that a specific syndrome is associated with the primary degenerative mitral lesion, numerous questions remain unanswered. A principal cause of confusion is the use of the term 'prolapse', which essentially ...
Feigenbaum H - - 1992
Echocardiography plays a major role in the management of patients with mitral valve prolapse (MVP). The technique has greatly enhanced our understanding of the pathophysiology, epidemiology and natural history. There are major and minor echocardiographic diagnostic criteria for prolapse. Major criteria involve the mitral leaflets and include late systolic posterior ...
