Gastrointestinal bleeding due to colonic angiodysplasia can be associated with calcified aortic stenosis. This association is referred to as Heyde's syndrome. Aortic valve replacement can prevent recurrent gastrointestinal bleeding in these cases. We describe the case of a 46-year-old woman with congestive heart failure related to aortic stenosis, and severe anemia, with multiple angiodysplasias on the ileum and colon. After aortic valve replacement, there were no further episodes of bleeding and her hemoglobin levels normalized.
