The Mean

Aim: The aim of this study was to assess the left atrial (LA) function in severe rheumatic mitral stenosis (MS) patients using two-dimensional speckle tracking echocardiography (STE) and its correlation with clinical symptoms and echocardiography parameters. Methods: A total of 120 subjects (80 patients with isolated severe MS [mitral valve area (MVA) ≤1.5 cm2] in sinus rhythm and 40 healthy controls) underwent comprehensive echocardiography including STE for assessment of LA strain [reservoir strain (LASr), conduit strain (LAScd) and contractile strain (LASct)]. Results: The mean MVA in cases was 0.93 ± 0.21 cm2. The mean values of LASr (14.73 ± 8.59%), LAScd (-7.61 ± 4.47%) and LASct (-7.16 ± 5.15%) among cases were significantly less (p< 0.001) when compared to controls where the values were 44.11 ± 10.44%, -32.45 ± 7.63%, -11.85 ± 6.77% respectively. Thus the compensatory LA contractile function was also compromised. The New York Heart Association (NYHA) class III, II and I dyspnea was present in 37 (46.25%), 38 (47.5%) and 5 (6.25%) subjects respectively. All the three LA strain parameters showed a trend towards decline with increase in severity of MS, increase in LA size, increase in mean and peak diastolic transmitral gradients and with higher NYHA functional class. Conclusion: Left atrial dysfunction is common in severe rheumatic MS as suggested by severely reduced LA reservoir, conduit and contractile strain. Early and timely intervention in these patients irrespective of NYHA functional class is advocated as it may likely improve the LA function and avoid clinical deterioration.

Abstract Background Functional tricuspid regurgitation (TR) is common among patients with left heart disease and may recur during the follow-up period after selective tricuspid valve annuloplasty (TVA). This study aims to analyse the relationship between left atrial (LA) strain and the degree of preoperative functional TR and to explore the role of LA strain in predicting TR recurrence. Methods This study included 63 patients with rheumatic mitral stenosis who underwent mitral valve replacement and concomitant TVA. Additionally, 20 healthy controls were enrolled. Preoperative conventional LA echocardiographic parameters and LA strain were measured. The association between LA strain and preoperative functional TR severity was analysed by Pearson correlation. Predictors of recurrent TR were determined by multivariate logistic regression analyses. Results Compared with the control group, the mitral stenosis group developed a significant impairment in terms of LA strain. The degree of preoperative functional TR exhibited moderate correlations with LA reservoir strain (r = − 0.57) and LA conduit strain (r = 0.48). During a median follow-up period of 66.4 ± 36.4 months, TR recurred in 18 patients. Preoperative LA reservoir strain and the mean transmitral gradient were predictors of postoperative TR recurrence. When the two indexes were combined to establish a prediction, the sensitivity and specificity of prediction increased. The area under the receiver operating characteristic curve of the combined indicator was higher than those of the single indicators (0.90 vs. 0.70 and 0.72). Conclusions LA strain correlates with preoperative functional TR severity in patients with rheumatic mitral stenosis. The LA reservoir strain and preoperative mean transmitral gradient are independent predictive factors for recurrent TR after TVA.
