Table 1. Two-Dimensional and 3D Quantitative Variables in Mild, Moderate, and Severe MR as Assessed by the 2D Integrative Method.

Mild MR
(n=15)		 Moderate MR
(n=34)		 Severe MR
(n=34)
3D VCA, cm2 0.15±0.06 0.34±0.09 0.66±0.21
2D ROA, cm2 0.13±0.05 0.25±0.08 0.57±0.25
MR volume, mL 25±11 42±12 83 ±37
VCW, cm 0.29±0.11 0.47±0.15 0.84±0.16
JA/LAA 0.17±0.06 0.29±0.09 0.40±0.12

MR indicates mitral regurgitation; VCA, vena contracta area; ROA, regurgitant orifice area; VCW, vena contracta width; and JA/LAA, ratio of jet area to left atrial area.

One-way ANOVA test was used to compare mean values for variables among different groups (all P<0.001).
