A 52-year-old woman was admitted with sudden onset of acute arterial occlusion in the right lower limb. We found 3-4/6 diastolic murmur and, in the ECG, rapid ventricular response in atrial fibrillation. The patient underwent an emergency operation. We applied transthoracic and transesophageal echocardiography to investigate the etiology of thromboembolism and diagnosed the patient with mitral stenosis. The patient was recommended for a mitral valve surgery. Preoperative coronary angiography revealed a normal picture. The mitral valve was resected in the operation. We also performed carbon-coated bileaflet prosthetic valve replacement. The left atrial appendix was ligated. The patient did not have any postoperative clinical problems. Having recommended appropriate medical treatment, the patient was discharged. In conclusion, thromboembolism and atrial fibrillation in patients with rheumatic heart diseases should be kept in mind throughout the diagnosis process.
