Alveolar Walls in Mitral Stenosis

Abstract
Pathologic alterations of alveolar walls in 95 autopsied patients with mitral stenosis were not frequent. The most frequently encountered change was capillary dilatation, and in 83 per cent of the patients, even this change was slight or absent. Other alterations were focal and involved only small proportions of the area of tissue examined. A generalized increase in the thickness of basement membranes could not be demonstrated.
