Figure 2: Transcatheter Aortic Valve Implantation for Bicuspid Versus Tricuspid Aortic Valve Stenosis.
Top: Schematic presentations of bicuspid and tricuspid aortic valves. Type 0 and 1 indicate bicuspid aortic valve with no raphe, and 1 raphe, respectively. Bottom: Cumulative all-cause mortality rates in patients with bicuspid aortic valve stenosis (AS) (orange) and tricuspid AS (blue) in a propensity score matched cohort. Event rates were compared using the win ratio test. Source: Yoon et al., 2017,[23] reprinted with permission from Elsevier.
