Supports 3D-TOE feasibility for AVA assessment; leaves open need for outcome validation versus 2D-TTE.
Is real-time 3D-TOE feasible, reliable, and concordant with 2D-TTE for assessing aortic valve area in patients with moderate-to-severe aortic stenosis?
Real-time 3D-TOE is a feasible and reliable method for assessing aortic valve area in aortic stenosis, though it yields slightly smaller values than standard 2D-TTE.
