Abstract:Objective: Patients with rheumatic mitral stenosis, despite having normal left ventricular ejection fraction (LV EF), have ventricular dysfunction in the form of impaired longitudinal excursion. Tissue Doppler velocity is a useful indicator for assessment of long-axis ventricular shortening and lengthening. The aim of our study was to evaluate the effect of percutaneous balloon mitral valvuloplasty (PBMV) on LV function in rheumatic MS and to study echocardiographic parameters with M-Mode and Tissue Doppler Im… Show more
“…Although EF is preserved in the majority of patients with pure MS (3), a subclinical LV dysfunction could be present (4,5). Nevertheless, the etiology and prevalence of LV dysfunction are still debated, with studies reporting estimates ranging from 21% to 77% (6,7). In addition to EF, other echocardiographic parameters can be used to assess LV dysfunction, such as mitral annular plane systolic excursion (MAPSE) and myocardial performance index (MPI).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
