Did the Angiodysplasia Associated With Heyde's Syndrome Disappear Spontaneously?: A Case Report

Abstract Background: Multidisciplinary clinical manifestations of Heyde's syndrome and finite accuracy of corresponding examinations toward Heyde's triad make it easily omitted or misjudged in practice. Moreover, aortic valve replacement is often delayed because of the contradiction between anticoagulation and hemostasis. Herein, we present a rare case of atypical Heyde's syndrome whose confirmed intermittent bleeding angiodysplasia was not observed via mesenteric arteriography again, but severe bleeding was dramatically improved by transcatheter aortic valve implantation(TAVI) following laparotomy.Case presentation: A 64-year-old female experienced refractory gastrointestinal bleeding and deteriorating exertional dyspnea with a history of hypertension. Exploratory laparotomy was performed because the hemorrhage persisted and repeated transfusions. The subsequent histological examination revealed angiodysplasia. Heyde's syndrome was not suspected until she bled again combined with aortic valve stenosis detected by echocardiography 3 years later. TAVI was consequently performed in a stable condition with the invisibility of angiodysplasia. The post-procedure and follow-up were uneventful.Conclusions: The visible figures of angiodysplasia or shortage of HMWM-vWFs should not be indispensable for the clinical diagnosis of Heyde's syndrome. Laparotomy could be a bridging therapy to aortic valve replacement for severe hemorrhagic patients, and TAVI may benefit high-risk patients with a stable condition.
