title: [Epidemiological, clinical and ultrasonographic aspects of right-sided infective endocarditis in Senegal: 6 cases].
abstract: Right-sided infective endocarditis accounts for 5 to 10% of endocarditic involvement and usually affects the tricuspid valve. The purpose of this report is to describe epidemiological, clinical and echocardiographical aspects of 6 cases of right-sided infective endocarditis observed in the Cardiology Department of Aristide Le Dantec Hospital in Dakar, Senegal from December 2007 to February 2010. Diagnosis was based on Duke's modified criteria. There were 3 men and 3 women with a mean age of 28.2 years (range: 20 and 43). Five of the 6 patients presented tricuspid endocarditis including one case associated with pulmonary endocarditis. In another case, pulmonary endocarditis was associated with aortic endocarditis. Infective endocarditis was acute in three cases and primary in four. One case of infective endocarditis was observed in a tetralogy of Fallot. Fever was present in 4 cases with an mean temperature of 38.4 degrees C (range, 37.2 to 40 degrees C) and heart failure was present in 5 cases. In 2 patients, blood cultures were positive for Staphylococcus aureus. All patients had leucocytosis with a neutrophilic predominance. Doppler echocardiography depicted vegetations in all cases. Contributing factors included congenital heart disease in 1 case, insertion of a venous catheter in 2 and dental infection in 2. No patient was addicted to intravenous drugs or infected by HIV. Outcomes included one in-hospital death with signs of refractory heart failure. Right-sided endocarditis is often primary and is dominated by the tricuspid involvement. It affects both sexes. Contributing factors include venous catheterization during the postpartum period and dental infection. Prevention requires strict asepsis during venous catheter insertion, treatment of dental infections and improved management of congenital heart disease.
