Parametric coronary bifurcation model that represents the left descending coronary artery with its first diagonal branch: top (a) and lateral (b) view. D _PMB proximal main branch diameter, D _DMB distal main branch diameter, D _SB side branch diameter, α distal angle, β main branch angle, L _P−PMB plaque length in the proximal main branch, L _P−DMB plaque length in the distal main branch, L _P−SB plaque length in the side branch. The black arrows at the plaque location in (b) highlights the plaque eccentricity. Dashed lines indicate the locations where pressure were measured for FFR calculations
