Streptococcus gallolyticus infective endocarditis in a patient with systemic lupus erythematosus: a three-dimensional echocardiography evaluation.

ABSTRACT

A 42 year-old woman was referred to our hospital with a history of fever and poor general status for the last 30 days. She presented tachycardia and a systolic apical murmur. Laboratory tests revealed leukocytosis of 13,100/mL, hemoglobin of 8.4g/dL and positive systemic lupus erythematosus antibodies (anti-Ro/SSA, anti-La/SSB, anticardiolipin, and antinuclear antibodies); blood culture was positive for Streptococcus gallolyticus. Three-dimensional transesophageal echocardiography was performed and revealed multiple mitral valve vegetations, with leaflet perforation and important mitral regurgitation, as well as large aortic vegetation, with cusp perforation and severe regurgitation. Additionally, a small vegetation was observed on the tricuspid valve, which presented moderate regurgitation. Threedimensional transesophageal echocardiography provides appropriate visualization of complications resulting from infectious endocarditis.
