Diagnoses of right-sided empyema complicating tricuspid valve endocarditis during transesophageal echocardiography.

A 25-year-old man, who was a known intravenous drug user, underwent transesophageal echocardiography as part of investigation for suggested infective endocarditis. Tricuspid valve infective endocarditis was diagnosed. The simultaneous visualization of right-sided empyema, previously undiagnosed, by transesophageal echocardiography, led to operative treatment by thoracoscopy and right lung decortication.
