Cardiac MR
Due to the important prognostic indicators of the function of the right ventricle in patients with PAH. Cardiac MR is performed in some patients to accurately evaluate the size, morphology and function of the right ventricle.
It is also used for follow-up of right heart hemodynamics for follow-up purposes.
Poor right ventricular function is indicated by the following according to the ACCF/AHA 2009 Expert consensus document on pulmonary hypertension:
- Stroke volume ≤25ml/m^2.
- Right ventricular end-diastolic volume ≥84ml/m^2( Most appropriate marker of right ventricular failure in the follow-up.)
- Left ventricvular end-diastolic volume ≤40ml/m^2
Pulmonary artery stiffness measured by relative cross sectional area change ≤16% also has implications on mortality rate.
