Abstract:
The association between aortic stenosis and gastrointenstinal bleeding due to acquired von Willebrand syndrome (AVWS) has been well established. We report a patient with AVWS from underlying severe endocarditis-associated aortic regurgitation and pre-existing mitral regurgitation. Cardiovascular disease-related AVWS occurs from a selective loss of the largest multimers of von Willebrand factor from high shear forces, and desmopressin leads to transient clinical improvement.
