Background : Mitral stenosis (MS) is the most common valvular heart disease. Thromboembolism is one of the most important complications of MS, especially when it is associated with atrial fibrillation (AF).Patients with sinus rhythm (SR) are also sussceptible to this complication when it is associated with left atrial appendage (LAA) dysfunction .LAA dysfunction is an independent predictor of thromboembolism in mitral stenosis. Objectives: To investigate whether there is a relation between mitral annular velocities obtained by Doppler tissue imaging (DTI) and LAA function determined by transoesophageal echocardiography (TEE) and to determine if the annular velocities can predict the presence of the inactive LAA in MS. Methods: Sixty MS patients were evaluated by transthoracic echocardiography and all patients underwent transesophageal echocardiography. The annular systolic (S-wave) and diastolic (Emand Am-waves) velocities were recorded. Inactive LAA was defined as LAA emptying velocity <25 cm/sec. Patients were divided into three groups; group AI (n = 18): sinus rhythm (SR) and LAA emptying velocity e”25 cm/sec, group AII (n =22): SR and LAA emptying velocity <25cm/sec and group B (n = 20): atrial fibrillation. Results: Thrombus was detected in 14 patients and spontaneous echo contrast (SEC) was detected in 48 patients. Both S-wave and peak LAA emptying velocities were decreasing, while SEC frequency and density were increasing from group A to group B. There was a positive correlation between LAA emptying vs. S-wave and LAA emptying vs. Am velocities (p < 0.001, r = 0.708 and p< 0.001, r=0.495). Multivariate regression analysis showed that only S-wave is the independent predictor of inactive LAA (p = 0.001, odds ratio = 0.133, 95% CI = 0.032–0.556). In patients with SR, the cutoff value of S-wave was 14 cm/sec for the prediction of the presence of inactive LAA (sensitivity: 92.3%, specificity: 95.3%). Conclusions: S-wave is an independent predictor of inactive LAA and a useful parameter in estimating inactive LAA in MS with SR..

BACKGROUND: The purpose of this study was to prospectively evaluate a large group of consecutive, non-anticoagulated patients with RHD (rheumatic mitral stenosis) and to analyze the left atrial appendage function in relation to left atrial appendage clot and spontaneous echo contrast formation in patients who were in SR vs. in AF. METHODS AND RESULTS: This is a hospital based observational study conducted in department of cardiology, S. M. S. MEDICAL COLLEGE and associated hospital, Jaipur, Rajasthan; between march 2016 to august 2017. We prospectively studied clinical and echocardiographic parameters of LA/LAA in 303 consecutive patients with mitral stenosis who underwent trans-esophageal echocardiography and correlated it with spontaneous echo contrast and left atrial appendage clot. The mean age of the patients was 32.94 years. One hundred thirty seven (45.21%) patients were in atrial fibrillation and 166 (54.79%) patients were in sinu rhythm. We found a statistically significant difference in the age of presentation (29.16/33.93/36.68 Yr; P =0.006/<0.001), MVA (1.17/0.8/0.69 cm2; P=<0.001/0.024), LA diameter (39/47.24/50 cm; P=<0.001/<0.001), LAA emptying velocity (45/26.43/15 cm/sec; P=<0.001/<0.001) and EF (37.49/30.67/23.7%; P=<0.001/0.001) among the patients without spontaneous echo contrast /clot vs. with spontaneous echo contrast vs. with spontaneous echo contrast & clot. By using student t-test, we found that there was a statistically significant difference in age of presentation, BMI, MDG, LA diameter, LAA emptying velocity and EF in patients who were in sinus rhythm vs. atrial fibrillation (P<0.05). Incidence of spontaneous echo contrast was 68.67% vs. 91.97% in patients in sinus rhythm vs atrial fibrillation, while that of SEC & CLOT both was 4.22% vs. 33.58% in patients in SR vs AF. In a subgroup of the patients with LA/LAA clot, the LA diameter (55.14 : 49.98 CM; P=0.057) and the LAA emptying velocity ( 15.14 : 15.26 CM/Sec; P=0.923) were not significantly different among patients in SR vs in AF. CONCLUSION: In the patients with severe mitral stenosis, besides atrial fibrillation, a subgroup of patients in normal sinus rhythm with depressed left atrial appendage function had a higher risk of clot formation in left atrial appendage and these patients should be routinely anticoagulated for prevention of clot formation.
