| Mid right ventricle (mm) | 0.628 | 0.120 | 0.063 |
| Right ventricle fractional area change (%) | <0.001 | <0.001 | <0.001 |
| Right ventricle tricuspid annular plane systolic excursion (mm) | <0.001 | <0.001 | 0.353 |
| Right ventricle S’ (m/sec) | 0.127 | <0.001 | 0.134 |
| Mean pulmonary artery pressure (mmHg) | <0.001 | 0.024 | 0.080 |
| Right ventricle systolic pressure (mmHg) | 0.460 | 0.590 | 0.131 |
| Right atrium size (mm) | <0.001 | 0.520 | 0.210 |
| Right atrium end systolic area (cm2) | 0.176 | <0.001 | 0.014 |

P-values were calculated by paired t-test.
