Comparison of two patients with mitral stenosis and importance of sinus rhythm: case report

We present two woman patients have rheumatic mitral stenosis (MS). They complained of about shortness of breath and palpitation. First patient, she had had two stroke without any sequela (respectively 7 years and 4 years ago). And she has atrial fibrillation (AF) in electrocardiography (ECG). Another woman patient didn’t have any complaint before. Latter patient has sinus tachycardia in ECG. Transthoracic echocardiography (TTE) disclosed severe mitral valve stenosis and left atrial dilatation in both patients. But first patient has multiple thrombus in left atrium. Mitral valve surgery was suggested for both patients. In conclusion maintenance of sinus rhythm, in the patients who had MS, is very important for both the protection of left atrial thrombus and the reduction of the development of systemic embolus related to it.
