Figure 8.

(Graphical abstract) Idealized schematic representing the simple 2D anatomical model used to predict risk of coronary obstruction during transcatheter aortic valve replacement, DLC2D/d, which is the calculated minimum distance from a point on leaflet calcium (Pc) to a point on the upper ostium of the coronary artery (Po). The optimal percent sensitivity and specificity of the 2D model, DLC2D/d, is compared to the current guidelines, height (h) and sinus of Valsalva diameter (SOVd), and a previous computational study DLC/d to predict coronary obstruction for high risk patients with height (h) < 14 mm and/or sinus of Valsalva diameter (SOVd) < 30 mm.
