SummaryAcquired von Willebrand syndrome (AVWS) may complicate severe aortic valve stenosis, due to a reduction in the haemostatically more efficient large von Willebrand factor (VWF) multimers. This study was designed to analyse the relevance of VWF abnormalities and haemorrhagic diathesis in severe aortic valve stenosis. Forty-one consecutive patients undergoing valve replacement were investigated: seven had minor bleeding symptoms in their recent history; 10 (24.3%) had a reduced VWF collagen binding (VWF:CB) to VWF antigen ratio, and 33 (80.5%) had a decrease in large VWF multimers. The shortage of large multimers was not associated with any accumulation of small VWF multimers (apparently ruling out any increased VWF proteolysis), nor was there any increase in VWF propeptide, which excludes a shorter VWF survival. The risk of developing VWF abnormalities was higher in patients with rheumatic valve disease than in degenerative cases (p=0.025) and in valves with <50% of residual endothelial cells (p=0.004). Bleeders differed from non-bleeders in that they had a higher mean transvalvular gradient and a more marked decrease in large VWF multimers. VWF abnormalities did not exacerbate peri-operative blood loss, however – a finding consistent with the full correction of these VWF abnormalities, seen already on the first postoperative day and persisting for up to six months after surgery. According to the data obtained in our cohort of patients VWF abnormalities are common in severe aortic stenosis, particularly in cases of rheumatic valve disease, but loss of the largest multimers does not seem to cause clinical bleeding in most patients.

Introduction von Willebrand disease is the most common hereditary coagulopathy and is characterised by a deficiency in the quantity or quality of the von Willebrand factor. Heyde Syndrome, in contrast, is an acquired form of von Willebrand syndrome (AVWS) due to calcific aortic valve stenosis, characterised by gastrointestinal bleeding from angiodysplasia. Case presentation A 73-year-old patient presented with severe gastrointestinal bleeding and stated that she suffered from hereditary von Willebrand disease. Upon echocardiography, a severe aortic valve stenosis was found, and hence the suspicion of additional AVWS was raised. Since endoscopic interventions and conservative therapeutic approaches did not result in a cessation of the bleeding, transcatheter aortic valve implantation (TAVI) was performed to stop the additional shear stress on von Willebrand factor. This resulted in cessation of the bleeding. Conclusion Retrospectively, this life-threatening gastrointestinal bleeding was a result of severe Heyde Syndrome, which could be alleviated by TAVI. Whether the patient had suffered from inherited von Willebrand disease in the past, remains uncertain. AVWS should be considered in patients with suspected inherited von Willebrand disease and concomitant severe aortic valve stenosis, since it constitutes a treatable cause of a potentially severe bleeding disorder.
