The devices and procedures used in preparing the aortic valve models. (a) Morphotype-specific leaflet-trimming three-dimensional templates for preparing pericardial leaflets. (b) Pericardial leaflets in tricuspid aortic valve (TAV), asymmetric bicuspid aortic valve (ABAV), and symmetric BAV models. Bovine pericardium is pressed on the templates and cut along their edges. (c) Morphotype-specific leaflet-suturing guides. Annular margins of pericardial leaflets (C) are sutured to the aortic wall along the annular curve of the suturing guide (C′). (d) TAV, ABAV, and symmetric BAV models with annular diameters of 24 mm. A: free margin; B: commissural margin (length of 5.2 mm); C: annular margin; C′: annular curve; D: coaptation height (length of 6.2 mm); E: depth of the central portion of the leaflets from the upper edge of the commissures (length of 2.7 mm); F: leaflet length (length of 20 mm).
