[Infectious endocarditis of a healthy heart in an infant].
The case of a 22 months old child with no previous medical history hospitalised for an acute infection with pyrexia, arthritis, meningitis and leukocytosis with polynucleosis is reported. All bacteriological investigations were sterile; the search for soluble antigen and serological tests were negative. Antibiotic therapy (Ampicillin and Thiamphenicol) cured the meningitis and arthritis. On the 10th day of treatment the temperature rose, a systolic murmur was detected and echocardiography showed the presence of a large vegetation on the anterior mitral leaflet. Three weeks later (on Ampicillin and Amikacine), asymptomatic abolition of the femoral pulses and disappearance of the vegetation on echocardiography were observed. Angiography confirmed obstruction at the bifurcation of the aorta. Surgical removal of the embolism resulted in revascularisation of the femoral artery and was followed by apyrexia. This infant probably developed endocarditis on a healthy heart. It was complicated by systemic embolism and mitral regurgitation which at present is well tolerated.
