Does mitral valve intervention improve right ventricular global longitudinal strain in patients with rheumatic mitral valve disease?
2D speckle tracking echocardiography can detect subclinical right ventricular dysfunction in mitral stenosis, which demonstrates significant improvement following mitral valve intervention.
RV strain may aid monitoring mitral stenosis response; hypothesis-generating for outcome impact in prospective studies.
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.

Chowdekar et al. (2021) conducted an observational in Rheumatic mitral valve disease (n=90). Mitral valve intervention vs. Pre-intervention baseline was evaluated on Right ventricular global longitudinal strain (RVGLS). Right ventricular global longitudinal strain was significantly impaired in mitral stenosis patients prior to intervention and improved significantly following intervention.
