Conclusions
The AutoMVQ analysis is feasible in TTE and TOE examinations of the MV,
applicable in patients who need to be treated surgically or with
transcatheter therapies. The level of agreement of all mitral annulus
measurements between TTE and TOE is strong enough to allow for the less
invasive TTE diagnostic method for our patients and give the option for
annulus assessment in patients with contraindications for cardiac CT or
TOE. However, when a more extensive anatomical and functional MV
interrogation is deemed necessary for proper decision making, and the
patient’s characteristics allows it, TOE should be preferred over TTE.
Further clinical studies with large series of cases are needed in order
to establish 3D TTE as an accurate and reproducible method for annulus
assessment compared to TOE.
