Table 3.
Reproducibility of annulus excursion and AMA(d) by two-dimensional speckle tracking echocardiography. Values are intraclass correlation coefficients (ICC). ICC was considered as poor when ICC<0.4, fair when ICC=0.40–0.59, good when ICC=0.60–0.74, and excellent when ICC≥0.75. Numbers in parentheses are 95% CIs
Intra-observer | Inter-observer | |
---|---|---|
AEr (mm) | 0.91 (0.84–0.96) | 0.69 (0.23–0.88) |
MEp (mm) | 0.86 (0.65–0.94) | 0.75 (0.49–0.89) |
FE (mm) | 0.97 (0.93–0.99) | 0.94 (0.86–0.98) |
AMA(d) (°) | 0.85 (0.60–0.97) | 0.75 (0.38–0.90) |
AEr, maximum right aortic annular point excursion; MEp, maximum post-mitral annular point; FE, maximum fibrous excursion; AMA(d), difference between maximum and minimum aortomitral angles.
