Project Description

Transcatheter aortic valve implantation (TAVI) is a first-line therapy for severe aortic stenosis in which a catheter-based valve delivery system is advanced through the femoral artery into the stenosed aortic valve and uses balloon inflation to deploy and implant the new TAVI valve. Illustrated “before” and “after” procedural views in parts A and C show gross pathology, actions and positions of the catheter, delivery system, and valve, and the end results of TAVI. Direct comparisons with “before” and “immediately after” aortograms in parts B and D provide verification for accuracy of the illustrations, further clinical context, and procedure details. Composition and visual hierarchy of color, contrast, saturation, texture, and other techniques are used to create an easy-to-follow overview of TAVI. In aiming to maximize the figure’s accessibility for those with visual impairments, high contrast colors and values were used next to each other, and bright blue or cooler hues were solely used for instruments and catheters which may be accessible to people with various forms of colorblindness. Almost all text colors pass or exceed the minimum recommended 7:1 contrast ratio for content accessibility. Variety in text hierarchy (color, weight, size, and tracking) may benefit those with vision impairments to distinguish between label types and captions.
