CMR planimetry may improve non-invasive AVA assessment in severe AS; leaves open its role in clinical decision-making pending prospective validation.
Does CMR planimetry accurately and reliably measure aortic valve area compared to TTE, TOE, and cardiac catheterization in patients with severe aortic stenosis?
CMR planimetry is a highly reliable and accurate non-invasive tool for evaluating severe aortic stenosis, offering superior diagnostic performance compared to TTE and TOE when referenced to cardiac catheterization.
