Prevalence of Right Ventricular Abnormalities on Transthoracic Echocardiography and CT
| Echocardiogram (TTE) | n (%) |
|---|---|
| TTE, any sign of RV dilatationa (n = 107) | 38 (36) |
| TTE, any sign of RV impairment (n = 107) | 50 (47) |
| TTE tricuspid annular plane systolic excursion < 17 mm (n = 35) | 13 (37) |
| TTE RVd/LVd > 0.9 (n = 54) | 9 (17) |
| TTE D-shapesystolic (n = 73) | 14 (19) |
| TTE tissue Doppler velocity tricuspid valve annulus < 9.5 (n = 30) | 10 (33) |
| TTE acute cor pulmonale (n = 49) | 7 (14) |
| TTE visual right ventricular systolic impairment (n = 107) | 33 (31) |
| CT | n (%) |
| CT RVd/LVd > 0.9 (n = 107) | 58 (54) |
| CT RVd/LVd > 1.0 (n = 107) | 36 (34) |
| CT RVa/LVa > 0.9 (n = 107) | 19 (18) |
| CT RVa/LVa > 1.0 (n = 107) | 9 (8) |
LVa = left ventricular area, LVd = left-ventricle end-diastolic diameter, RV = right ventricle, RVa = right ventricular area, RVd = right-ventricle end-diastolic diameter, TTE = transthoracic echocardiography.
aRV dilatation defined as an RVd > LVd upon visual assessment, or an RVd/LVd of > 0.9.
