COMPARISONS OF FLOW-GRADIENT PATTERNS IN SEVERE AORTIC STENOSIS BETWEEN BICUSPID AORTIC VALVES AND TRICUSPID AORTIC VALVES

Background: Flow-gradient patterns in severe aortic stenosis (AS) with preserved ejection fraction provides prognostic information. We compared the prevalence of four flow-gradient patterns in severe AS between bicuspid and tricuspid phenotypes. Methods: 187 patients with severe AS (103 bicuspid vs
