Assessment of Left Ventricular Deformation in Rheumatic Mitral Stenosis Patients (Speckle Tracking Study)

Abstract

Objectives: to utilize speckle tracking echocardiography to assess the left ventricular (LV) systolic function in rheumatic mitral stenosis (MS) patients. Methods: 100 patients were evaluated with pure rheumatic MS who were contrasted with 50 healthy individuals of matched age, gender, and risk factors. We assessed the mitral valve area (MVA) utilizing planimetry and the mean transmitral pressure gradient; then based on MVA, the patients were split into two groups. MS patients in the first group were classified as having severe symptoms, while patients in the second group had moderate symptoms. Speckle tracking echocardiography was employed to determine LV subclinical systolic dysfunction. Results: Regarding clinical data and LVEF, no statistically significant distinctions were seen between the groups. Global LV longitudinal strain was significantly diminished in MS patients. Both global basal and mid segments strain were significantly diminished in MS patients (P <0.001). On the contrary, with relation to the global apical strain, no statistically significant distinction existed between the groups under investigation (P=0.96). The global basal, mid, and apical longitudinal strain exhibited a significant negative relationship with the mean transmitral pressure gradient. Conclusions: MS patients
