Infective endocarditis in association with pyogenic vertebral osteomyelitis is rarely observed. We report an 80-year-old man with infective endocarditis and pyogenic vertebral osteomyelitis requiring reoperation due to aortic prosthetic valve dysfunction. He suffered from back pain as the initial symptom, and he was admitted to our hospital. On magnetic resonance imaging, vertebral osteomyelitis was revealed, and antibiotics were started. On blood sampling α-streptococcus was identified and infective endocarditis was diagnosed. He responded to the antibiotic treatment. Despite the improvement in his general condition and the inflammatory parameters of blood samples, the aortic prosthetic valve dysfunction progressed. On echocardiography, aortic regurgitation worsened to 4/4, and the ejection fraction decreased from 72 to 46%. As heart failure was apparent, we performed a redo aortic valve replacement. Tears were found in the leaflets of the removed prosthetic valve (Hancock II). The 21-mm Carpentier-Edwards PERIMOUNT valve (CEP Magna Ease TFX) was replaced. His post-operative course was uneventful, and intravenous administration of ampicillin was continued. Oral rifampicin was also continued. On the 69th post-operative day, he was discharged and was ambulatory. Although we have no evidence that the tissue valve deterioration had resulted from bacterial damage, we were able to confirm that the structural valve deterioration involved bacterial contact in this case. Patients with infective endocarditis and pyogenic vertebral osteomyelitis should be treated cautiously regardless of whether or not the inflammation is controlled.

We report a case of massive endobronchial hemorrhage after cardiopulmonary bypass, and its successful treatment utilizing a bronchial blocker tube without circulatory support. An 85-year-old woman underwent mitral and tricuspid valves repair for mitral stenosis and regurgitation, and tricuspid regurgitation. The repairs were performed uneventfully. The patient was weaned from cardiopulmonary bypass. After protamine infusion, massive endobronchial hemorrhage occurred through the tracheal tube. On fiberoptic bronchoscopy, prompt identification and selective occlusion of the hemorrhage source was performed by a Coopdech endobronchial blocker tube (Daiken Medical Co., Ltd, Osaka, Japan). Postoperative contrast-enhanced computed tomography revealed thrombogenic pseudoaneurysm of the right middle lobe pulmonary artery. We speculated that Swan-Ganz catheters induced endobronchial hemorrhage. The patient did not experience any further hemorrhage. She was discharged from our hospital on the 25th postoperative day in good condition.
