Quantitative 3D analysis of MV Characteristics
The geometry of mitral complex in healthy controls, MVPt- and MVPt+
patients are summarized in Table 3. Expectedly, MVPt+ group had a
significantly higher tenting volume index (TVi), while MVPt- group had a
similar TVi to normal controls.
AML TVi and AML angle was comparable in normal controls and MVPt- group,
but MVPt+ group had a significantly larger AML angle. Interestingly, PML
TVi and PML Angle was lowest in MVPt- group, intermediate in normal
controls, and highest in MVPt+ group. (Figure 2B). Annular dimensions,
including ALPM diameter, AP diameter and AAi and annular circumference
index, were significantly different among the groups, being lowest in
normal controls, intermediate in MVPt- group, and highest in MVPt+ group
(Figure 2C).
MVP patients (MVPt- and MVPt+ group) had a larger prolapse height index
(PHi) and PVi compared with normal group. Notably, MVPt- patients had
significantly larger PHi and PVi compared with MVPt+ patients (Figure
2D).
MVPt+ group was not associated with a lower AWCHR as AWCHR is comparable
among three groups (Figure 1E).
