Feasibility, reproducibility and characteristics of coronary bifurcation type assessment by three-dimensional optical coherence tomography
Fig 5
Representative 3D-OCT bifurcation types.
Parallel type: Jailed stent struts at the SB ostium can be attached towards the SB wall by KBI in parallel type bifurcations in which the distal bifurcation angle is 50°. Perpendicular type: Jailed stent struts at the SB ostium cannot be sufficiently dilated to fit the elliptical SB ostial rim in perpendicular type bifurcations with a distal bifurcation angle of 106°.
