Key result
3D echocardiography adds morphologic detail over 2D echo in ~31% of aortic valve assessments.
Why the study?
The value of three-dimensional echocardiographic assessment of the aortic valve had not been established.
Does three-dimensional echocardiography improve the evaluation of the aortic valve compared to two-dimensional echocardiography in patients undergoing transesophageal echocardiography?
Population
32 patients with various aortic valve morphologies, mean age 56.1 years
Comparison
Three-dimensional echocardiography vs two-dimensional echocardiography
Design
Cross-sectional study

Supports 3D echocardiography for aortic valve evaluation in TEE; leaves open effects on clinical decisions or outcomes.

Does three-dimensional echocardiography improve the evaluation of the aortic valve compared to two-dimensional echocardiography in patients undergoing transesophageal echocardiography?
Three-dimensional echocardiography of the aortic valve is feasible and provides additional morphological information compared to 2D echocardiography in nearly a third of patients.
Kasprzak et al. (1998) conducted a cross-sectional in Aortic valve evaluation (n=32). Three-dimensional echocardiography vs. Two-dimensional echocardiography was evaluated on Feasibility and quality of aortic valve reconstructions (excellent or adequate). Three-dimensional echocardiography of the aortic valve yielded excellent or adequate image quality in 81% of patients, providing additional morphologic information in 31% compared to 2D echo.
