About this study

The purpose of this study is detection of relationship between biomarkers and the severity of AS (echocardiographic hemodynamics/CT-calcium load).  Detection of relationship between biomarkers to the consequences of AS on the LV (echo remodeling parameters and speckle-tracking LV strain).  Detection of differences on echocardiographic and CT-calcium load AS severity assessments between tricuspid and bicuspid valves.  Detection of biomarker associations with AS hemodynamics, CT-calcium load, LV remodeling and LV strain between tricuspid and bicuspid phenotypes. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
