Table 2: Evaluation of possible pulmonary disease.
| 1 | 2 | 3 | 4 | 5 | |
| Transthoracic Echocardiography | Mild pulmonary hypertension | No evidence of pulmonary hypertension | Moderate pulmonary hypertension, severly reduced RV function |
Mild pulmonary hypertension | Moderate pulmonary hypertension |
| CT Chest | Honycombing and reticular changes consistent with mild interstitial lung disease |
Enlarged pulmonary arteries, no interstitial changes | Ground glass opacities and diffuse interstitial markings, consistent with fibrotic changes |
No interstitial changes | - |
| Pulmonary Function Tests | Mild restriction without air trapping FEV1/FVC 83% DLCO 80% |
- | Severe gas transfer
Defect FEV1/FVC 83% DLCO 45% |

CT: computed tomography; FEV: forced expiratory volume; FVC: forced vital capacity; DLCO: diffusion capacity for carbon monoxide.
