Pulmonary Hypertension Associated With Necrotizing Pulmonary Arteritis

Necrotizing arteritis limited to the pulmonary arteries has been described occasionally as a complication of mitral stenosis (Parker and Weiss, 1936), of Eisenmenger's complex (Old and Russell, 1947), and in patients dying with right heart failure of uncertain causation (McKeown, 1952). One such case in this last category, in which cardiac catheterization gave clear evidence of pulmonary hypertension, has recently come under our observation.
