To evaluate the significance of episodes of cerebral embolism in patients with mitral valve disease in Korea, 128 patients with echocardiographic diagnosis of mitral valve disease were examined. Among these, 82 patients had predominant mitral stenosis. The clinical features of 82 patients with mitral stenosis have been reviewed to elucidate the factors favoring cerebral embolism which occurred in 19 patients, i.e., incidence of 23.2%.Atrial fibrillation was present in 16 of 19 patients with cerebral embolism (84.2%). Cerebral embolic episodes occurred in 16 of 47 patients with atrial fibrillation (34.0%).The mean age (55.3 ± 12.1 years) of patients without cerebral embolism was significantly older than that (43.2 ± 14.6 years) of patients without cerebral embolism (P<0.005).There was no significant relationship between the incidence of embolism and sex, left atrial thrombi, left atrium/aortic root diameter, mitral valvular orifice area, mitral valvular vegetation or calcification, left ventricular enddiastolic dimension or left ventricular posterior wall thickness.Cerebral embolism is common in patients with mitral stenosis in our country. The presence of atrial fibrillation and low cardiac output increase the attack of cerebral emboli whereas the severity of mitral stenosis, as judged by valve area, may not correlate with the occurrence of emboli. The best treatment for cerebral embolism is prevention. Therefore, we believe that more vigorous treatment of patients with mitral valve disease who are old or associated with atrial fibrillation as well as previous embolic history is indicated.
