Abstract: | A 51-year-old woman was admitted with increasing shortness of breath. Preoperative evaluation disclosed MSr + ASr + TR. She had been undergone a splenectomy at 35-year-old for hereditary spherocytosis (HS). The patient underwent successful mitral valve replacement with a No. 25 Bj?rk-Shiley (BS) valve, aortic valve replacement with a No. 21 BS valve, and tricuspid valve annuloplasty by means of membrane oxygenator (COBE). Haptoglobin and poloxamer 188 were used for prevention of hemolysis during extracorporeal circulation. No significant hemolysis occurred intra-or postoperatively. A very rare case of open heart surgery associated with HS was reported. |
