Key result
Intraoperative TEE shows poor agreement with preoperative TTE for diastolic function grading in CABG.
Why the study?
The agreement between preoperative TTE-based and intraoperative TEE-based diastolic dysfunction grading algorithms in cardiac surgical patients was unclear.
Does intraoperative TEE-based diastolic function grading agree with preoperative TTE-based grading in CABG patients?
Observational (n=101)
No
Does intraoperative TEE-based diastolic function grading agree with preoperative TTE-based grading in CABG patients?
Intraoperative TEE and preoperative TTE algorithms for grading diastolic dysfunction show poor agreement in CABG patients, producing fundamentally different results.
Answers are grounded in this paper and cite their sources.
Intraoperative TEE-TTE disagreement cautions against interchangeable use in CABG; Level 3 evidence leaves optimal diastolic assessment unresolved.

Harvey et al. (2021) conducted an observational in Coronary artery bypass grafting (CABG) (n=101). Intraoperative transesophageal echocardiography (TEE) diastolic function grading vs. Preoperative transthoracic echocardiography (TTE) diastolic function grading was evaluated on Disagreement between TTE and TEE diastolic function grading algorithms (OR 15.33, 95% CI 4.77-49.30, p=< 0.0001). Intraoperative TEE-based diastolic function grading showed poor agreement with preoperative TTE grading in CABG patients (OR for disagreement 15.33; 95% CI 4.77-49.30; p < 0.0001).
