Does three-dimensional echocardiography accurately and reproducibly assess aortic valve area compared to standard echocardiography and cardiac catheterization in patients with aortic stenosis?
Three-dimensional echocardiography provides an accurate and reproducible non-invasive quantitative assessment of aortic valve area in patients with aortic stenosis, performing at least as well as TEE with better interobserver variability.
