A 46-year-old woman with mitral stenosis, WPW syndrome, hemolytic anemia due to spherocytosis, and hypothyroidism with Hashimoto's thyroiditis, was admitted with palpitations and dyspnea due to paroxysmal atrial fibrillation with a rapid ventricular response, and was treated by electrical cardioversion. We selected surgical intervention to treat the mitral stenosis and WPW syndrome, as some tachycardia episodes due to atrial fibrillation have resulted in repeated congestive heart failure. In 1983 we simultaneously performed a division of the posteroseptal accessory pathway and a mitral valve replacement with a biopros-thetic valve under cardiopulmonary bypass, using a membrane oxygenator after splenectomy to compensate for the hemolytic anemia due to spherocytosis. Her postoperative course was favorable and she is now in good health with no episodes of tachycardia, congestive heart failure nor anemia occurring during the 10 years that have followed the operation. Simultaneous surgery for WPW syndrome combined with other cardiac abnormalities and hematologic disorders achieved acceptable results in this case. (Jpn Circ J 1996; 60: 171 - 176)
