The pathogenesis of PH is complex and just beginning to be elucidated. In patients with congenital heart disease, left-to-right intracardiac shunting increases flow through the pulmonary vasculature, this causes shear forces that disrupt the vascular endothelium and activate cellular mechanisms critical to the pathogenesis and progression of PAH. | The pathogenesis of PH is complex and just beginning to be elucidated.
