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).
