Determinants of 3D Vena Contracta Area
All MVP patients presented significant and holosystolic MR.
Morphological determinants of 3D VCA are summarized in Table 1. In
univariate analysis, factors significantly associated with 3D VCA
included annular area index (AAi), prolapse volume index (PVi), TVi and
PV + TV and AHCWR. In stepwise multivariate analysis, only PVi and TVi
was independently associated with 3D VCA.
