[Infective endocarditis in Morocco through the experience of a hospital department]

Infective endocarditis is a grave disease because of a high level of morbidity and mortality. We conducted a retrospective analysis of 100 patients hospitalized for infective endocarditis from January 2009 until December 2015. The mean age was 41 years with a male predominance. Infective endocarditis occurs on a native valve (77 patients), prosthetic valves (12 patients), Pacemaker (7 patients) and congenital heart disease (4 patients). The diagnostic delay was 77 days on average. The fever was present in 85 patients. Blood cultures were negative in 54 patients. Echocardiography allowed visualizing the vegetations in 95 patients. In patients with prosthetics valves, a paraprosthetic regurgitation was diagnosed in 54 % of these patients and vegetation in 18 %. The main complications are heart failure (42), neurological (19), spleen (10) and renal (23) complications. The evolution under medical treatment was marked by the clinical-laboratory improvement in 57 patients, the lack of improvement with persistent fever in 21 patients. The mortality rate of our series is 23 %. Only seven patients underwent urgent surgery for hemodynamic and infectious indications. At the end of this work, it is emphasized that the epidemiological profile of infective endocarditis does not follow the changes of Wold. Its management is difficult in our context (significant diagnostic delay, often negative blood cultures, high level of morbidity, lack of recourse to early surgery). The improvement of this disease consistes of the prevention of acute articular rhumatism and the establishment of an heart team endocarditis to adapt international recommendations to our context.
