Abstract Severe pulmonary arterial hypertension whether idiopathic or secondary is characterized by structural alterations of microscopically small pulmonary arterioles. The vascular lesions in this group of pulmonary hypertensive diseases show actively proliferating endothelial cells without evidence of apoptosis. In this article we review pathogenetic concepts of severe pulmonary arterial hypertension and explain the term complex vascular lesion commonly named plexiform lesion with endothelial cell dysfunction . apoptosis proliferation interaction with smooth muscle cells and transdifferentiation. Introduction Severe pulmonary arterial hypertension PAH whether idiopathic or associated with known causes secondary forms may have a .
