Abstract:
Objective To measure right ventricular longitudinal strain in patients with mitral stenosis (MS) by 2D speckle tracking imaging(2D-STI), and explore the clinical value of this technique in evaluating right ventricular systolic function in these patients. Methods Fifty-five patients with rheumatic mitral stenosis who were treated in our hospital were randomly selected. The mitral valve orifice area (MVA) and right ventricular systolic function index including tricuspid lateral annular systolic velocity (S′), tricuspid annular plane systolic excursion (TAPSE), RV index of myocardial performance (RIME) and right ventricular fractional area change (FAC)were measured by transthoracic echocardiography(TTE), and the pulmonary systolic pressure(PASP) was estimated by the tricuspid regurgitation method； 2D speckle tracking imaging (2D-STI) was used to measure the free-wall right ventricular longitudinal strain (RVLSFW), and the patients were divided into two groups according to the RVLSFW value: group A with RVLSFW<-19%, and group B with RVLSFW≥-19%. Results There were significant differences in MVA, PASP, TAPSE, S′, RIMP, FAC and RVLSFW between the two groups (P<0. 05), and the right ventricular systolic function decreased more significantly in patients with RVLSFW≥-19% mitral stenosis (P<0. 05);RVLSFW was positively correlated with PASP and RIMP (r= 0. 521, 0. 511, P<0. 05), and negatively correlated with MVA, TAPSE, FAC and S′ (r=-0. 521, -0. 410, -0. 435, -0. 385, P<0. 05). Conclusion Right ventricular longitudinal strain can evaluate right ventricular systolic function in patients with mitral stenosis, and provide more reliable information for clinical practice.
