3DTEE may improve AVA accuracy over 2DTEE; leaves open whether this affects decisions or outcomes.
Does volumetric 3DTEE improve the accuracy of anatomical aortic valve area measurements compared to standard 2DTEE in patients with aortic stenosis?
3DTEE provides more accurate anatomical aortic valve area measurements than 2DTEE, which overestimates AVA due to aortic annular motion.
