title: Pneumococcal endocarditis.
abstract: Among 369 patients with native valve infective endocarditis observed during a 14-year period, 17 were related to S: pneumoniae. Fourteen of them were observed in the last 7 years. At the time of admission 13 exhibited purulent meningitis, 6 of them being comatose. An apparent portal of entry was present in 13 patients including Pneumonia (n = 11) and otitis media (n = 2). Major alcoholism was present in 6 cases. The mean delay between the onset of fever and the discovery of the cardiac murmur was 15 days (range 1 to 60). Twelve patients exhibited congestive heart failure with acute pulmonary oedema in 9. The aortic valve was involved in 12 and the mitral valve in 7 (in 2 patients both mitral and aortic valves were involved). Myocardial and/or annular abscesses were found in 7 patients. Nine patients underwent surgical procedure (3 died) whereas 6 comatose patients were not operated on and died. The overall mortality was 59%. Although antibiotics are effective, the severity of anatomical lesions leads to prompt surgical treatment. The high mortality is mainly due to purulent meningitis.
