Key result
TEE identifies acute aortic dissection entry sites with ~90% sensitivity.
Why the study?
The usefulness of transesophageal echocardiography in diagnosing entry sites and associated dissections in acute aortic dissection was evaluated.
Does transesophageal echocardiography accurately locate intimal fenestration and side branch involvement in patients with acute aortic dissection?
Observational (n=69)
No
Does transesophageal echocardiography accurately locate intimal fenestration and side branch involvement in patients with acute aortic dissection?
Transesophageal echocardiography is highly accurate for locating the entry site and most side branch involvement in acute aortic dissection, though it has limitations for evaluating the brachiocephalic artery.
Supports TEE for aortic entry localization in acute dissection; leaves open reliable brachiocephalic assessment in observational cohorts.

Nishigami et al. (1999) conducted an observational in Acute aortic dissection (n=69). Transesophageal echocardiography (TEE) vs. Intraoperative inspection was evaluated on Sensitivity of TEE for locating the entry site of aortic dissection. Transesophageal echocardiography demonstrated a 90% sensitivity for locating the entry site in acute aortic dissection, with high sensitivity for aortic valve (85%) and coronary artery (83%) involvement.
