Background: Three-dimensional (3D) speckle-tracking echocardiography
(3DSTE) is one of the newest development in non-invasive imaging offering
simultaneous 3D evaluation of atria and valvular annuli. 3DSTE was used to
analyze correlations between left atrial (LA) volume changes and mitral annular
(MA) dimensions and functional properties in healthy adult subjects.
Methods: A total of 297 healthy subjects were enrolled
in this retrospective cohort study, from which insufficient quality of images was
responsible for the exclusion of 98 cases (33%). The remaining study population
consisted of 199 healthy adults without valvular regurgitation/stenosis in sinus
rhythm (mean age: 33.5
