Impact-R and Heyde Syndrome

Thursday, December 29th, 2011

This is a case of a 79-year old man with severe aortic stenosis and recurrent GI bleeding. This case study by Schmid, et.al. proposes that Impact-R to determine platelet function may be more time- and cost-effective compared to electrophoretic analysis of vWF multimers.

Severe aortic stenosis with bleeding diathesis is also known as Heyde syndrome. The pathophysiology: loss of high molecular weight vWF multimers in high shear stress conditions leads to a platelet type von Willebrand disease (acquired vWD, vWD type 2B) which can explain the bleeding tendencies of a patient with severe aortic stenosis.
