Hypertrophic obstructive cardiomyopathy, bleeding history, and acquired von Willebrand syndrome: response to septal myectomy.
Ontology highlight
ABSTRACT: Bleeding with severe aortic stenosis is linked to acquired von Willebrand syndrome and loss of high-molecular-weight multimers of von Willebrand factor. Valve replacement resolves bleeding tendency and loss of high-molecular-weight multimers. We report outcomes in 5 patients with symptomatic obstructive hypertrophic cardiomyopathy and spontaneous gastrointestinal, mucosal, or excessive postsurgical bleeding in whom acquired von Willebrand syndrome was documented. All 5 patients underwent surgical septal myectomy with resolution of acquired von Willebrand syndrome.
