Journal of Cardiothoracic Surgery 2011 6 131 http content 6 1 131 JCTS JOURNAL OF CARDIOTHORACIC SURGERY CASE REPORT Open Access Prosthetic valve endocarditis caused by Staphylococcus capitis report of 4 cases Tamaki Takano Yoshinori Ohtsu Takamitsu Terasaki Yuko Wada and Jun Amano Abstract Although Staphylococcus capitis is considered to be a rare causative organism for prosthetic valve endocarditis we report 4 such cases that were encountered at our hospital over the past 2 years. Case 1 was a 79-year-old woman who underwent aortic valve replacement with a bioprosthetic valve and presented with fever 24 days later. Transesophageal echocardiography revealed an annular abscess in the aorto-mitral continuity and mild perivalvular regurgitation. We performed emergency surgery 5 days after the diagnosis of prosthetic valve endocarditis was made. Case 2 was a 79-year-old woman presenting with fever 40 days after aortic valve replacement with a bioprosthesis. Transesophageal echocardiography showed vegetation on the valve and she underwent urgent surgery 2 days after prosthetic valve endocarditis was diagnosed. In case 3 a 76-year-old man presented with fever 53 days after aortic valve replacement with a bioprosthesis. Vegetation on the prosthetic leaflet could be seen by transesophageal echocardiography. He underwent emergency surgery 2 days after the diagnosis of prosthetic valve endocarditis was made. Case 4 was a 68-year-old woman who collapsed at her home 106 days after aortic and mitral valve replacement with bioprosthetic valves. Percutaneous cardiopulmonary support was started immediately after massive mitral regurgitation due to prosthetic valve detachment was revealed by transesophageal echocardiography. She was transferred to our hospital by helicopter and received surgery immediately on arrival. In all cases we re-implanted another bioprosthesis after removal of the infected valve and annular debridement. All .
