[Succesful case of open heart surgery in a dialysis patient with infectious endocarditis and severe bone marrow suppression: report of a case].

We report a case of infectious endocarditis due to Corynebacterium species. The patient was 71-yearold man, who was on dialysis and had tracheostomy preoperatively. He went to the hospital complaining of dyspnea. He was diagnosed with congestive heart failure and treated after admission. His respiratory condition was exacerbated and he was intubated. Respiratory management prolonged over 2 weeks. Tracheostomy was performed. One month after admission, cardiac echo showed massive aortic valve regurgitation and vegetation of aortic valve. The patient was transferred to our hospital to undergo operation for aortic valve regurgitation and infectious endocarditis. In our hospital, labo data showed severe bone marrow suppresssion with white blood cell(WBC)1,700/µl, red blood cell(RBC)259×104/µl, platelet(PLT) 5.0×104/µl. Aortic valve replacement was performed. Because the patient had tracheostomy, we incised sternal bone in a T shape to avoid mediastinitis. After operation, patient recovered well and left hospital 48th day after the operation.
