Conjugated bile acids are elevated in severe calcific aortic valve stenosis.

ABSTRACT: Calcific aortic valve (AV) stenosis (CAVS) is a disease associated with significant morbidity and mortality in the aging population. Recently, bile acids have been shown to play a significant role in many disease processes, and untargeted metabolomic analyses of CAVS patient valves have shown a disrupted bile acid pathway. We aimed to understand the changes in human valvular bile acids in relation to CAVS severity. A total of 100 human AVs were collected from patients undergoing AV replacement surgery. Bile acids were quantified by ultrahigh performance liquid chromatography coupled to MS/MS. Patients with mild aortic stenosis (AS) showed a distinct valvular bile acid composition compared with moderate and severe AS groups, with five bile acids being significantly elevated in patients with
