Traitement de l'hypertension portopulmonaire en classe fonctionnelle OMS IV ou lorsque les critères de faible risque ne sont pas atteints
L'hypertension portopulmonaire de classe fonctionnelle OMS IV — ou lorsque les paramètres hémodynamiques pulmonaires ne satisfont pas aux critères de faible risque — identifie une sous-population à sévérité élevée nécessitant une stratégie thérapeutique distincte et intensifiée.

The prostacyclin agonists (prostanoids) are reserved for patients with a type IV functional class according to the World Health Organization or any patient with PH not meeting low-risk criteria.
They can be used as bridge therapy for patients on the transplant list.
Supplementary oxygen is recommended for patients with oxygen saturation <89%, as per ILTS guidelines.
Diuretics, which are frequently used for the treatment of portal hypertension, are important in the management of PH and volume overload.
Generally, prostacyclin agonists have shown an improvement in pulmonary hemodynamics, functional class, and the ability to exercise.
It also appears to significantly improve pulmonary hemodynamics for patients with moderate to severe PAH and reduce the mean arterial pulmonary pressure and PVR.
