Intraoperative TEE Screening
A pattern-based interpretation tool for intraoperative TEE findings — focused on perioperative hemodynamic meaning, not formal reporting.
TEE range and limitations
The arch and descending aorta are accessible by TEE. The ascending aorta is not reliably visualized due to tracheal interposition. Cannulation and clamp sites cannot be fully assessed by TEE alone — epiaortic ultrasound or direct surgical assessment is required.

Common intraoperative scenarios
LV pump failure after CPB separation
Is this preload, contractility, or SAM? Compare with pre-CPB LV size and function.
Work through caseRCA territory ischemia after CPB separation
Distinguish fixed RCA obstruction from air embolism. Integrate ST changes, CVP rise, and RV findings.
Work through caseAortic dissection just after CPB initiation
Know what TEE can see well and what it cannot. Arch and descending are in range; ascending is not.
Work through caseCPB context
TEE also plays a key role in CPB cannulation guidance, line confirmation, and de-airing checks before separation from bypass — core intraoperative TEE roles outside this v1 scope.
