The following is a summary of “Segmental and global longitudinal strain measurement by 2-dimensional speckle tracking echocardiography in severe rheumatic mitral stenosis,” published in the November 2023 issue of Cardiology by Mehrabi-Pari et al.
Researchers conducted a retrospective study to investigate the potential of two-dimensional speckle tracking echocardiography (2D-STE) in detecting subtle left ventricular (LV) dysfunction in patients with severe rheumatic mitral stenosis (MS).
They conducted a case-control study comparing 65 patients with severe rheumatic mitral stenosis (MS) and preserved ejection fraction (EF ≥ 50% measured by conventional echocardiographic methods) with 31 healthy control subjects. All patients underwent 2D speckle tracking echocardiography (2D-STE) for left ventricular strain measurement, in addition to conventional echocardiography, utilizing a VIVID S60 echocardiography device.
The results showed absolute strain values in myocardial segments 1–8, 10, and 12 (comprising all basal, mid anterior, mid anteroseptal, mid inferior, and mid anterolateral segments) exhibited a significant decrease in patients with severe mitral stenosis compared with the control group (P< 0.05 for all). The absolute value of global longitudinal strain (GLS) was higher in the control group (-19.56 vs. -18.25; P=0.006). Following adjustment for age, gender, and systolic blood pressure, the discrepancy in GLS between the two groups was as follows, mean difference=-1.16; 95% CI: -2.58–0.25; P= 0.110.
Investigators concluded that LV dysfunction was detected in patients with severe rheumatic MS using 2D-STE.
