An Uncommon Presentation of Heyde's Syndrome: Gastric Antral Vascular Ectasia in a Patient With Severe Aortic Stenosis

Heyde's syndrome signifies the link between aortic stenosis (AS) and bleeding due to angiodysplastic changes. While colonic angiodysplasia is commonly implicated, gastric antral vascular ectasia (GAVE) represents a rarer manifestation in this context. We report the case of a 72-year-old male with severe AS who had recurrent upper gastrointestinal bleeding due to GAVE. Endoscopic hemostasis was achieved with argon plasma coagulation (APC). This case illustrates the need for multidisciplinary intervention while managing such patients and makes a further case for recognizing GAVE in the context of Heyde's syndrome.
