Key result
TEE carries a ~2% rate of transient bacteraemia with no subsequent endocarditis.
Why the study?
The incidence of bacteraemia and fever during transoesophageal echocardiography was not well established to guide antibiotic prophylaxis.
Does transoesophageal echocardiography cause clinically significant bacteraemia requiring antibiotic prophylaxis in patients undergoing the procedure?
Population
82 consecutive patients undergoing transoesophageal echocardiography
Comparison
Blood cultures before, during, and after TEE
Design
Prospective cohort study
Follow-up
6 months

Low bacteraemia incidence during TEE suggests limited infection risk; leaves open need for larger studies on prophylaxis.
Cohort (n=82)
Does transoesophageal echocardiography cause clinically significant bacteraemia requiring antibiotic prophylaxis in patients undergoing the procedure?
The study demonstrates a very low risk of true bacteremia and no endocarditis following TEE, suggesting routine antibiotic prophylaxis is unnecessary.
Roudaut et al. (1993) conducted a cohort in Patients undergoing transoesophageal echocardiography (n=82). Transoesophageal echocardiography was evaluated on Incidence of bacteraemia. Transoesophageal echocardiography was associated with a 2.4% incidence of transient bacteraemia (2 of 82 patients) and no cases of endocarditis at 6 months.
