Segmental and Global Longitudinal Strain Measurement by 2-Dimensional Speckle Tracking Echocardiography in Severe Rheumatic Mitral Stenosis.

The present study aimed to detect subtle left ventricular (LV) dysfunction in patients with severe rheumatic mitral stenosis (MS) by measuring global and segmental longitudinal strain with a two-dimensional speckle tracking echocardiography (2D-STE) method. In this case-control study, 65 patients with severe rheumatic MS and preserved ejection fraction (EF ≥ 50
