“…Younan [13] found a significant positive correlation between LV GLSS with EF% (r = 0.33, p = 0.01) & MVA (r = 0.40, p = 0.001) and a significant negative correlation between LV GLSS with PG (r = 0.36, p = 0.007) and MG (r = 0.40, p = 0.003) in patients with MS. In addition, there was a significant positive correlation between LV GLSSr with EF% (r = 0.39, p = 0.02) and MVA (r = 0.52, p = 0.001) and a significant negative correlation between LV GLSSr with PG (r = 0.43, p1 = 0.005) and MG (r = 0.42, p = 0.006) in patients with MS.…”

Introduction: Current echocardiographic parameters have a limitation in assessing mitral valve (MV) apparatus in rheumatic mitral stenosis (MS) patient. In the current study, we use 2 dimensional (2D) longitudinal strain (S) and strain rate (Sr) imaging in evaluating the papillary muscle longitudinal strain (LS) as an objective and quantitative echocardiographic parameter with high reproducibility in the assessment of MV apparatus in patients with mild to moderate rheumatic MS with preserved ejection fraction (EF%). Patients and Method: The study included 40 patients with established diagnosis of MS subdivided in to 31 patients with moderate MS (mean age: 32 ± 5) and 9 patients with mild MS (mean age: 31 ± 6). 20 healthy individuals (mean age 31 ± 6) as a control for cases. The mitral valve area (MVA) was estimated using planimetry and pressure half time (PHT) methods. 2D longitudinal systolic S and Sr imaging was carried out for all participants from the apical long axis (LAX), 4 chamber (4C), 2 chamber (2C) views. Global longitudinal systolic S and Sr were estimated by averaging the 3 apical views. Longitudinal myocardial strain of papillary muscle PMs was assessed by the use of the free strain method from apical 4 chamber view for the antrolateral papillary muscle (APM) and apical long axis view for postromedial papillary muscle (PPM). Results: Patients with MS had significantly decreased longitudinal LV systolic S and Sr in comparison with control group (p < 0.001) despite no significant differences in LV EF%, LVESD and LVEDD were determined between the 3 groups. APM-LS and PPM-LS had significantly decreased values in patient with MS in comparison with control group (p < 0.001). Conclusion: Patients with MS and preserved EF% had decreased APM-LS & PPM-LS in comparison with control group, and had decreased longitudinal LV systolic S and Sr when compared with control group. 2D strain as well as Sr imaging might be a useful method for assessment of mitral valve apparatus in patients with MS & preserved EF%.

“…19 Two-dimensional echocardiography images were obtained at end-expiration from LV long-axis apical four-, three-and two-chamber (A4C, A3C and A2C) views with frame rates of 60-80 frames per second. 20 Three consecutive cardiac cycles were recorded and averaged. 21 LV endocardial surface was traced manually in the three views by a point-and-click approach.…”

Aims: Right ventricular (RV) systolic function is an important predictor of mortality but has been poorly studied in chronic rheumatic mitral regurgitation (CRMR). We studied RV systolic function using speckle-tracking echocardiography (STE) in patients with CRMR. Methods: Seventy-seven patients with CRMR and 40 healthy controls were enrolled in a cross-sectional study at Chris Hani Baragwanath Hospital between January and October 2014. RV peak systolic strain (PSS) and left ventricular (LV) global longitudinal strain (GLS) were measured using Philips Qlab 9 STE software. Results: RVPSS was lower in CRMR patients compared to the controls (-16.8 ± 4.5 vs-19.2 ± 3.4%, p = 0.003) with no difference in conventional RV systolic function parameters (p = 0.39). RVPSS was lower in severe CRMR compared to moderate CRMR patients (-14.3 ± 4.23 vs-18 ± 4.18%, p < 0.0001). CRMR patients with LV systolic dysfunction had a greater reduction in RVPSS and LVGLS compared to those with preserved LV systolic function (p = 0.001). LVGLS and significant tricuspid regurgitation (TR) were independent predictors of RVPSS (p < 0.001). Conclusion: In CRMR patients, RVPSS was a more sensitive marker for detecting earlier RV systolic dysfunction than traditional RV functional parameters.
