Key result
Transesophageal echocardiography was associated with no significant bacteremia due to pathogenic oral flora (0%; 95% CI, 0.0-7.5%).

Supports negligible bacteremia risk with TEE; leaves open whether prophylaxis guidelines can safely change.

Does transesophageal echocardiography cause transient bacteremia in patients?
Transesophageal echocardiography is not associated with a significant risk of transient bacteremia, suggesting routine antimicrobial prophylaxis may not be necessary for many patients.
Steckelberg et al. (1991) conducted an observational in Patients undergoing transesophageal echocardiography (n=49). Transesophageal echocardiography was evaluated on Significant bacteremia due to pathogenic oral flora (95% CI 0.0-7.5). Transesophageal echocardiography was associated with no significant bacteremia due to pathogenic oral flora (0%; 95% CI, 0.0-7.5%).
