An Important Association With Lower Gastrointestinal Bleed: A Case of Heyde Syndrome.

The association between aortic stenosis and angiodysplastic gastrointestinal bleed is known as Heyde syndrome. It was first described in 1958 and has since received further medical attention. We present a case of an 86-year-old lady with a history of severe aortic stenosis that was admitted with gastrointestinal bleeding secondary to colonic angiodysplasia. A review of the literature showed mixed opinions with respect to the idea of causation versus coincidence; both theories are valid. However, studies that supported causation had a bigger study population and overall seem to be more plausible.
