5. Conclusion
Both semi-automated and manual 3D TEE for sizing of the aortic annulus
for TAVR is comparable to MSCT. 3D TEE methods are easily reproducible
and feasible. Newer semi-automated 3D TEE offers the best correlation to
MSCT. Hence 3D TEE is an excellent imaging modality for TAVR planning in
patients whom MSCT is either contraindicated or suboptimal.
