Abstract
A patient with mitral stenosis is reported who suffered from exertional cyanosis for the last eight years of his life. Radiologic examination of his chest demonstrated a diffuse pulmonary hemosiderosis, which was confirmed at autopsy. Physiologic studies in the last few weeks of life showed that the cyanosis was not due to impairment of oxygenation of the blood in the lungs but rather to slowed circulation, possibly augmented by local changes in the anatomy of the vessels of the skin.
