[Severe aortic stenosis in the elderly and cryptogenic intestinal bleeding (Heyde syndrome): a case report].

The Heyde syndrome describes the association between calcific aortic stenosis and intestinal bleeding. The pathophysiologic link between both entities has remained unclear so far. In several studies the intestinal bleeding has been attributed to angiodysplasia of the gut, with following cessation of the bleeding after replacement of the aortic valve. A case report.
