Micro-CT analysis of stent diameters, opening areas and stent length.

n = Location of bifurcation:1left anterior descending (LAD)/ramus diagonalis (RD) I,2LAD/RD II,3LAD/left circumflex,4right coronary artery: ramus interventricularis posterior/ramus posterolateralis dexter.*Measured before stent implantation by QCA.†Calculated with stent diameter given by manufacturer.‡Calculated with stent diameter assessed by Micro-CT.**Opening area was calculated using the circle formula area = π radius2. RLD: reference luminal diameter; QCA: quantitative coronary angiography.
