Infective endocarditis at the University Hospital of the West Indies. A revisit

ABSTRACT

Many countries have reported a change in the profile of infective endocarditis (IE) over the past three decades. The objective of this study was to evaluate the characteristics of IE from the autopsy service of the University Hospital of the West Indies (UHWI) during the last 15 years and to compare the results with that of an earlier study. There were 26 cases of IE during the period under review with a M:F ratio of 1.2:1. The ages ranged from 15 days to 74 years with a mean of 36.4 +/- 24.57 years. The largest number of cases (n = 7) occurred in the 10 to 19-year-age group. Cardiac predisposing factors were identified in 14 patients; nine with rheumatic heart disease, four with prosthetic valves and one with a bicuspid aortic valve. All vegetations were located on valves, the aortic being the most frequently involved followed by the mitral. Streptococcus species were the most common causative organisms followed by Staphylococcus aureus. Compared with the profile seen 15 years ago, there have been only minor changes in the characteristics of IE cases observed in the autopsy service at the UHWI
