Successful mitral valve replacement in patient with severe hemolytic anemia due to tight mitral stenosis

Abstract

A 43 year-old woman complained of palpitation and shortness of breath admitted to our hospital. Transthoracic echocardiography revealed severe mitral stenosis and moderate mitral regurgitation. In routine blood tests hemoglobin and lactate dehydrogenase levels were 7.6 g/dL, 520 IU/L respectively. Coombs test was negative. After studying the other intrinsic or extrinsic causes of hemolytic anemia patient’s anemia was diagnosed as intravascular hemolytic anemia due to tight mitral stenosis. Therefore, mitral valve replacement planned and performed. Hemolysis was resolved after the mitral valve replacement. In conclusion, we report a case of hemolytic anemia due to mitral stenosis resolved by mechanical mitral valve replacement.
