Why the study?
Does transthoracic echocardiography with nonstandard views accurately measure ascending aortic size compared to transesophageal echocardiography in patients with or without aortic disease?
Population
52 patients with or without aortic disease, mean age 65.5 years, 15% with aortic dilation >4.0 cm
Comparison
Transthoracic echocardiography with nonstandard… vs Transesophageal echocardiography (TEE)
Design
Cross-sectional, 2 blinded observers for each modality

TTE with nonstandard views correlates with TEE for ascending aorta; leaves open whether it can guide serial monitoring without TEE confirmation.
Does transthoracic echocardiography with nonstandard views accurately measure ascending aortic size compared to transesophageal echocardiography in patients with or without aortic disease?
Transthoracic echocardiography using nonstandard views is highly correlated with transesophageal echocardiography for measuring the ascending aorta, supporting its use for serial follow-up.
