A retrospective examination was made of eleven patients that developed prosthetic valve endocarditis (PVE) during the period from January 1960 to December 1987. Infection occurred in one patient within 60 days after surgery and in 10 thereafter. Causative organism was found in 6 patients. As organism, Staphylococcus species were noted in 4 patients and Peptstreptococcus was noted in one patient and Aspergyllus was noted in one patient. Three of eleven patients received medical treatment only and the other 8 patients were received surgical treatment. Mortality rate was 67% in medical group and 29% in surgical group. Two patients with medical treatment died of cerebral infarction about 40 days after the onset of PVE. In surgical group one patient died of uncontrollable Aspergillus infection and the other one died of dyspnea. No survivors who was treated surgically have developed reinfection or relapse of infection but four of them developed perivalvular leakage and needed reoperation. Absolute removal and closure of the valve ring abscess and reconstruction of defect should be considered for those needed surgical treatment to prevent reinfection and relapse developing.
