We assessed the Right Ventricular (RV) systolic function using two dimensional (2D) speckle tracking echocardiography (STE) in Mitral valve disease before and after intervention. 90 patients divided into 3 groups of Mitral stenosis [MS], Mitral regurgitation [MR] and MS with MR were the study subjects. All the patients were subjected to conventional echocardiography and measurement of Right ventricular global longitudinal strain (RVGLS). Prior to intervention, subjects who demonstrated normal RV function by conventional methods, it was found that RVGLS was impaired significantly in the MS and MS with MR groups but normal in the MR group. After intervention, the RVGLS improved significantly in the MS group but not in the other groups. Right ventricular systolic pressure (RVSP) had a significant negative correlation to RVGLS in all 3 groups.
我们使用二维斑点追踪超声心动图（STE）评估了二尖瓣疾病患者干预前后的右心室（RV）收缩功能。90 名患者分为二尖瓣狭窄[MS]、二尖瓣反流[MR]和 MS 合并 MR 三组。所有患者均接受了常规超声心动图和右心室整体纵向应变（RVGLS）测量。在干预前，常规方法显示 RV 功能正常的患者中，MS 和 MS 合并 MR 组的 RVGLS 明显受损，但 MR 组正常。干预后，MS 组的 RVGLS 显著改善，但其他组无变化。三组的右心室收缩压（RVSP）与 RVGLS 均呈显著负相关。
