Why the study?
Does biplane TEE accurately visualize the entire length of the ascending aorta and detect atheromas compared to direct anatomic measurement and epiaortic scanning in patients undergoing cardiac surgery?
Population
27 patients (19 male, 8 female; mean age 67 +/- 12 years) studied during cardiac surgery
Comparison

Reliance on biplane TEE for ascending aortic assessment warrants caution; cross-sectional data leaves open whether epiaortic scanning improves embolic risk stratification.
Does biplane TEE accurately visualize the entire length of the ascending aorta and detect atheromas compared to direct anatomic measurement and epiaortic scanning in patients undergoing cardiac surgery?
Biplane TEE has significant blind spots in visualizing the distal ascending aorta, limiting its utility for precannulation assessment of potentially embolic plaques.
Konstadt et al. (1994) studied this question.
