Lisa A. Freed,Daniel Levy,Robert A. Levine,Martin G. Larson,Jane C. Evans,Deborah L. Fuller,Birgitta T. Lehman,Emelia J. Benjamin +7 more
TL;DR: The prevalence of mitral-valve prolapse in the general population, as diagnosed with the use of current two-dimensional echocardiographic criteria, was lower than previously reported.
Journal ArticleDOI
Insights From Three-Dimensional Echocardiography Into the Mechanism of Functional Mitral Regurgitation Direct In Vivo Demonstration of Altered Leaflet Tethering Geometry
Yutaka Otsuji,Mark D. Handschumacher,Ehud Schwammenthal,Leng Jiang,Jae-Kwan Song,J L Guerrero,Gus J. Vlahakes,Robert A. Levine +7 more
TL;DR: LV dysfunction without dilatation fails to produce important MR, and functional MR relates strongly to changes in the 3D geometry of the mitral valve attachments at the PM and annular levels, with practical implications for approaches that would restore a more favorable configuration.
Journal ArticleDOI
Three-dimensional echocardiographic reconstruction of the mitral valve, with implications for the diagnosis of mitral valve prolapse.
Robert A. Levine,Mark D. Handschumacher,Anthony J. Sanfilippo,Albert A. Hagege,Pamela Harrigan,Jane E. Marshall,Arthur E. Weyman +6 more
TL;DR: It is shown that leaflets can appear to ascend above the mitral annulus in the apical four-chamber view, as they did in at least one view in all subjects, without actual leaflet displacement above the entire mitral valve in three dimensions, thereby challenging the diagnosis of prolapse by isolated four- chamber view displacement in otherwise normal individuals.
