Discussion
The main findings of our study were as follows: 1) MV anatomy can be
quantified by TTE using dedicated algorithms such as 4D AutoMVQ in the
vast majority of patients undergoing TOE for the same purpose, 2) there
is high level of agreement of all mitral annulus and leaflets
measurements between 3D TTE and TOE, 3) the mitral annulus dimensions
quantified by 3D TTE are abnormal in patients with MV pathologies,
atrial fibrillation, LV and LA dilatation, as compared to healthy
subjects.
