Sequential right-sided changes due to pulmonary hypertension (PH) detected by cardiovascular magnetic resonance (CMR) modalities
| Physiologic changes assessed by CMR | CMR sequence |
| Stiffening of the pulmonary artery with gradual increase in pressure at rest, leading to worsening of pulmonary artery compliance and reduced RAC | Cine Velocity-encoded phase contrast |
| Right ventricular hypertrophy, progressive right ventricular dilation with leftward shift in IVS or D-septum | Cine Strain imaging LGE Adenosine stress perfusion to assess cardiac ischaemia |
| Tricuspid regurgitation due to right ventricular dilation and valve annulus stretch | Cine Velocity-encoded phase contrast |
| Increased right ventricular pressure leading to a dilated right ventricle with leftward shift of the interatrial septum | LGE imaging for myocardial scar |
| Engorged vena cavae with pericardial effusion | Cine cardiac structure/function T1-weighted fast spin echo without fat suppression to assess pericardium Myocardial oedema imaging with T2 weighted sequences |
RAC: relative area change; IVS: interventricular septum; LGE: late gadolinium enhancement.
