3D TEE may enhance annulus sizing accuracy versus 2D in TAVI candidates; supports correlative data but leaves open outcome impact.
Do 3D imaging techniques provide more accurate aortic annulus measurements compared to 2D imaging in patients undergoing TAVI?
3D imaging techniques such as 3D TEE and DSCT should be used for aortic annulus measurement before TAVI, as 2D techniques systematically underestimate dimensions.
