Fig. 2

a, b Two guidewires initially pass through both the main RCA and RV branch. c The magnified image around the lesion shows the difference between the positions of the two guidewires in the RCA. The red arrow indicates the point where the guidewire branches off toward the RV branch. The red arrowhead indicates the true bifurcation point. d, e The OCT findings clearly show that the guidewire branches off toward the RV branch from a point more proximal than the true bifurcation point. d is a cross-sectional image at the distance indicated with the black bar in c, f. f The outlook of the lesion with the lotus root appearance after initial guidewire passage. Blue and green lines indicate the guidewires passing into the RV branch and main RCA, respectively
