Between 2003 and 2014, at Jichi Medical University Hospital, 11 patients with prosthetic valve endocarditis (PVE) underwent re-operation. There was 1 in-hospital death and 2 late deaths. The cause of death was cirrhosis, heart failure and sepsis, respectively. Emergency surgery, previous double valve replacement (DVR) and Staphylococcus infection were(More)
BACKGROUND The purpose of this study was to evaluate retrospectively the clinical performance of the Bicarbon valve (Sorin Biomedica Cardio, Saluggia, Italy) implanted at our center in Japan. METHODS Between January 1997 and December 2011, 415 patients in our institution were implanted with the Bicarbon valve. Nine of these recipients were excluded from(More)
Between December 2005 and November 2011, 11 patients with mitral valve regurgitation (MVR) resulting from native valve endocarditis underwent mitral valve plasty (MVP). These patients were aged 44.4 ± 11.3 years. The mean follow-up period of the patients was 3.1 ± 0.63 years. Five patients were men. Emergency or urgent surgery was required in 5 patients.(More)
A 67-year-old man experienced acute inferior myocardial infarction. Echocardiography and computed tomography showed massive pericardial effusion. He underwent emergency operation for ischemic ventricular free wall rupture. During the operation, an oozing type rupture was found on the inferior wall and the bleeding was completely controlled by applying(More)
A congenital left coronary artery anomaly originating from the right aortic sinus is a rare congenital defect associated with the risk of sudden death in young individuals. In most cases, the proximal portion of the anomalous left coronary artery exists between the ascending aorta and pulmonary trunk, and it has an intramural aortic course; this could(More)
A 73-year-old woman on hemodialysis was transferred to our hospital for surgical treatment of heart valve disease. She required both mitral and aortic valve replacement with mechanical valves, associated with tricuspid annuloplasty. After aortic de-clamping, a massive hemorrhage from the posterior atrioventricular groove was observed. Under repeated cardiac(More)
We report a case of cardiac sarcoidosis associated with mitral valve regurgitation. A 62-year-old woman with cardiac sarcoidosis was admitted for the treatment of an intractable mitral regurgitation. She had been treated for cardiac sarcoidosis with prednisolone, and she had undergone pacemaker implantation because of advanced complete A-V block 5 years(More)
Vacuum-assisted closure(VAC) therapy is mainly used for tissue defects. VAC therapy can remove exudate that could impair the healing process. We applied VAC therapy in patients considered at high risk of surgical site infection who underwent cardiovascular surgery via standard median sternotomy. Risk factors included advanced heart failure, obesity,(More)
