Isolated Tricuspid Valve Endocarditis in a Child with a Normal Heart

Abstract

Infective endocarditis localized in the tricuspid valve was observed in a previously completely healthy 10‐yeardd male. The pathogen was identified as Staphylococcus uureus. Twodimensional and Doppler echocardiography revealed rupture of the chordae tendineae and prolapse of the tricuspid septal leaflet with tricuspid regurgitation. Isolated infective tricuspid valve endocarditis is mostly confined to drug addicts, and, to out knowledge, the literature contains only four cases of this disease in children without heart disease. The present case is considered to represent an extremely rare condition.
