Comparison of mean values of tissue mitral annular displacement (TMAD) in different territories with the subgroups of systolic function
| LV systolic function | TMAD (mm) |
||
|---|---|---|---|
| AI | II | AA | |
| Normal (n = 14) | 10.640 ± 1.336a | 11.070 ± 1.141 | 9.930 ± 1.592 |
| Mild (n = 43) | 10.790 ± 1.103 | 7.720 ± 4.055 | 7.210 ± 4.313 |
| Moderate (n = 77) | 5.510 ± 3.995 | 9.750 ± 2.754 | 10.910 ± 1.041 |
| Severe (n = 15) | 2.470 ± 0.834a | 10.600 ± 1.298 | 11.070 ± 0.961 |
| Total (n = 149) | 7.210 ± 4.171 | 9.380 ± 3.182 | 9.770 ± 2.983 |
| P* | < 0.001 | 0.563 | 0.645 |
TMAD: Tissue mitral annular displacement; LV: Left ventricle; AI: Anterolateral and inferolateral left circumflex artery (LCX) territory; II: Inferior and inferoseptal right coronary artery (RCA) territory; AA: Anterior and anteroseptal left anterior descending (LAD) territory
Normal LV systolic function (more than 55%); Mild LV systolic dysfunction (45-54%); 3: Moderate LV systolic dysfunction (30-44%); Severe LV systolic dysfunction (less than 30%)
Analysis of variance (ANOVA) test
Post hoc test showed significant difference between the normal group and those with severe systolic (defined with superscript letter (a); P = 0.009).
