Key result
TTE alone linked to management decisions in only ~6% of S. aureus bacteremia cases vs TEE.
Why the study?
Whether performing transthoracic echocardiography before transesophageal echocardiography influences clinical management decisions in patients with Staphylococcus aureus bacteremia deemed to warrant TEE was not well studied.
Does performing TTE before TEE influence clinicians' decision making in patients with Staphylococcus aureus bacteremia deemed to warrant TEE?
Population
206 episodes of Staphylococcus aureus bacteremia deemed to warrant TEE
Comparison
Management decisions after TTE alone versus after TTE plus subsequent TEE
Design
Single-center retrospective observational analysis

TTE alone rarely informs S. aureus bacteremia management; leaves open whether routine TEE improves outcomes without randomized data.

Does performing TTE before TEE influence clinicians' decision making in patients with Staphylococcus aureus bacteremia deemed to warrant TEE?
Absolute Event Rate: 6.3% vs 86.4%
In patients with Staphylococcus aureus bacteremia who require TEE, performing a TTE first rarely prompts clinical management decisions before the TEE is completed.
Aldred et al. (2022) conducted an observational in Staphylococcus aureus bacteremia (n=206). Transthoracic echocardiography (TTE) alone vs. TTE plus subsequent transesophageal echocardiography (TEE) was evaluated on Any of 5 key patient management decisions taking place. Transthoracic echocardiography (TTE) alone prompted clinical management decisions in only 6.3% of Staphylococcus aureus bacteremia episodes, compared to 86.4% after both TTE and TEE.
