Transcatheter Aortic Valve Replacement Reverses Heyde Syndrome: A Case Report of Severe Aortic Stenosis and Gastrointestinal Bleeding

Type: article

Abstract: Background: Heyde syndrome is a rare condition characterized by the triad of severe aortic stenosis, gastrointestinal bleeding, and acquired type 2A von Willebrand syndrome. This case report highlights the diagnostic and therapeutic approach for a 72-year-old woman presenting with exertional chest pain, dyspnea, fatigue, and a history of melena. Methods: The diagnostic workup revealed severe microcytic anemia and a reduced vWF ristocetin-to-antigen ratio. Imaging confirmed severe degenerative aortic stenosis, while video capsule endoscopy identified angiodysplasia and telangiectasias in the small bowel as the source of gastrointestinal bleeding. Following evaluation by a multidisciplinary Heart Team, the patient underwent transcatheter aortic valve replacement (TAVR) with an Evolut Fx self-expanding prosthesis. Results: Post-procedural echocardiography showed mild paravalvular regurgitation. The patient’s clinical course was favorable, with resolution of anemia and no further gastrointestinal bleeding episodes. Conclusions: Heyde syndrome requires a high index of suspicion for diagnosis in patients with severe aortic stenosis and unexplained anemia or gastrointestinal bleeding. TAVR offers an effective treatment option that not only resolves valvular pathology, but also mitigates associated bleeding risks.
