Figure 1. Numerical prediction of coronary artery occlusion. A) Still frames of the balloon angioplasty virtual reproduction up to 22 mm of balloon diameter (Moving image 2). B) Angiographic inspection of LCA patency (Moving image 1). C) Time course of the percentage variation in LCA dimensions, during virtual balloon inflation. D) Geometrical rearrangement of the LCA configuration on a single cross-section. E) Balloon angioplasty, during diagnostic cardiac catheterisation, confirming LCA compression (Moving image 3). Ø indicates the diameter of the inflated balloon. A: aortic cross-sectional area; Ao: aorta; DMAX: maximum LCA diameter; dmin: minimum LCA diameter; LCA: left coronary artery
