[Infectious endocarditis. Experience of a service in Brazzaville. 47 cases]

The aim of this study was to report the authors' experience of infective endocarditis (IE) from 47 cases collected between 1976 to 1991. Infective endocarditis (IE) was documented with surgical (n = 9), microbiological (n = 26), and echocardiographic (n = 30) criteria. There were 11 male, 36 female: mean age, 26.2 +/- 10.3 years (extremes: 17 and 47). The authors noted a great importance of gynecological portal entry (13 cases), acute infective endocarditis (23 cases i.e. 48.9%), heart failure (39 cases i.e. 82.9%), and pulmonary (4 cases i.e. 8.5%) and systemic (8 cases i.e. 17.0% embolism. Surgical treatment was impossible in Brazzaville. Trans-thoracic echocardiography was performed in 38 cases and revealed vegetations in 30 cases i.e. 78.9%. Twenty patients died (42.5%) because heart failure. There was no significant difference in letality between infective endocarditis treated surgically or no, between native valve or prosthetic valve infective endocarditis, between culture negative or culture positive infective endocarditis (IE). This study corroborate that infective endocarditis is a heavy illness, characterized by high frequency of heart failure. The authors insist upon the prevention of infective endocarditis.
