Abstract

The transthoracic echocardiographic and clinical features of 71 consecutive patients with mitral stenosis were reviewed. Patients were divided into either Group 1 (without systemic embolism, n = 54) or Group 2 (with systemic embolism, n = 17). Left atrial dimension (LAD) was slightly smaller in group 1 than in group 2 (45.2 ± 8.6 mm vs. 48.8 ± 8.5 mm; p = NS). Mitral orifice area (MOA) was slightly larger in Group 1 than in group 2 (1.39 ± 0.56 cm2 vs. 1.32 ± 0.48 cm2; p = NS). Left atrial thrombus was detected in 4 (7%) patients in Group 1 and in 1 (6%) patient in Group 2 (p = NS). The age of the patients was slightly younger in Group 1 than in Group 2 (49.7 ± 15.4 vs. 54.4 ± 18.2; p = NS). The incidence of systemic embolism was not significantly different between those patients younger than 40 years of age and those patients older than 40 years of age. The incidence of atrial fibrillation (AF) was significantly higher in those patients older than 40 years of age as compared to those patients younger than 40 years of age. AF was noted in 33 (61%) patients in Group 1 and in 12 (71%) patients in Group 2 (p = NS). Of 71 patients, 45 were in AF and 26 were in sinus rhythm (SR). LAD was significantly larger in patients with AF than in patients with SR (49 ± 7.8 mm vs. 41 ± 7.8 mm; p < 0.001). MOA was slightly smaller in patients with AF than in patients with SR (1.30 ± 0.49 cm2 vs. 1.49 ± 0.61 cm2; p = NS). The age of the patients was slightly older in patients with AF than in patients with SR (53.4 ± 16.0 vs. 46.3 ± 15.6; p = NS). The overall incidence of systemic embolism in this study was 24% (17/71).
