title: [Surgical Treatment of Prosthetic Valve Endocarditis].
abstract: 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 common risk factors for all 3 cases. Two cases of patients that survived who underwent mitral valve replacement (MVR) and DVR for PVE after DVR were treated with multiple antibiotic courses for bacteremia associated with hemodialysis and colon cancer. One patient who underwent DVR after mitral valve plasty which was complicated with cerebral hemorrhage, had survived and was discharged. Of the aortic PVE patients, 2 cases of aortic valve replacement (AVR) using a mechanical valve, 1 case of aortic root replacement (ARR) using a mechanical valve, and 1 ARR using the homograft, were considered cured and never relapsed. A patient with aortic PVE, who underwent AVR after cesarean section for heart failure in birth period, has received ARR twice with the mechanical valve for recurrent pseudo-aneurysm of the left ventricular outflow tract. Since hemodialysis and colon cancer is a risk factor for recurrent PVE, it is necessary to consider the long-term administration of antibiotics after surgery.
