Although hemolytic anemia is a well-known complication of mechanical heart valve replacement, its occurrence is rare after mitral ring annuloplasty. A 57-year-old woman developed hemolytic anemia two months after mitral valve repair with ring annuloplasty. Transthoracic echocardiography revealed mild mitral regurgitation. Urine analysis showed the presence of hemosiderin. Following blood transfusion, clinical and laboratory improvement was observed. No further deterioration in anemia was seen and the patient remained asymptomatic during the follow-up. Although most cases of severe hemolysis after mitral valve repair require reoperation, hemolysis in the present case decreased with transfusion eliminating the need for reoperation.
