Right-Sided Endocarditis Due to Salmonella typhi

A case of right-sided endocarditis due to Salmonella typhi is described involving a native tricuspid valve in a child who was human immunodeficiency virus negative with no evidence of intravenous drug addiction. The patient had classic features of typhoid and tricuspid regurgitation without clinical evidence of bacterial endocarditis. Transthoracic echocardiography confirmed the tricuspid regurgitation. However, transesophageal echocardiography was necessary to demonstrate the vegetations affecting the tricuspid valve leaflets that made possible the diagnosis of endocarditis. The infection was cured with intravenous ceftriaxone and oral amoxicillin.
