Bleeding angiodysplasia: should we concentrate more on the aortic valve than on the bowel?

A case of bleeding from angiodysplasia in association with aortic stenosis is presented. The particular interest in this patient is that the bleeding ceased immediately after the insertion of a bioprosthetic valve and recurred when the valve restenosed. Furthermore, the bleeding again promptly resolved when the valve was exchanged for a metallic prosthesis despite long-term anticoagulation. The implications of these observations are discussed.
