Data on two- and three-dimensional optical coherence tomography guidance for the treatment for the bifurcation lesion.

This article comprised the data related to the research article entitled "Feasibility and usefulness of three-dimensional optical coherence tomography guidance for optimal side branch treatment in coronary bifurcation stenting" (Nagoshi et al., In press) [1]. In this article we reports details about two patterns of guide wire (GW) recrossing position after crossover stenting in bifurcation lesion classified with three-dimensional optical coherence tomography (3D-OCT) (Okamura et al., 2014) [2] and follow-up data about the treatment with percutaneous coronary intervention(PCI) for bifurcation lesion in terms of the two- (2D) or 3D-OCT guidance. Subgroup analysis about differences in the parameters between the proximal and the distal GW recrossing patterns are analyzed here.

Value of the data

The data presents two patterns of GW recrossing position after crossover stenting in bifurcation lesion classified with 3D-OCT (Okamura et al., 2014) [1].

The rate of incomplete stent apposition after kissing balloon inflation with the proximal or with the distal GW recrossing are mentioned.

Clinical and angiographical follow-up data of bifurcation stenting under 2D- or 3D-OCT guidance are shown in the article.

Data

Among a total of 150 cases, the guidewire recrossing through the distal cell was achieved in 126 cases(84%). Table 1 shows the data comparing the proximal and the distal guidewire recrossing.

Experimental design, materials and methods

Data subjects comprised the 3D-OCT bifurcation registry database (multicenter prospective study: 3 sites with 3D-OCT guided PCI and 7 sites with 2D-OCT guided PCI) and the Nakatsu OCT database (single-center retrospective study, before and after adoption of 3D-OCT reconstruction software). Bifurcation PCI cases meeting the following inclusion and exclusion criteria were extracted from the two databases and analyzed. The inclusion criteria were: (a) angiographically documented bifurcation lesion with ≥75% stenosis of the diameter at least one MV or SB, (b) SB diameter greater than 2.0 mm (visual assessment), (c) treated with crossover stenting followed by KBI under OCT guidance. Exclusion criteria were: (a) side branch <2 mm diameter (visual assessment), (b) in-stent restenosis, (c) congestive heart failure, (d) renal insufficiency with serum creatinine level >1.5 mg/dl except for hemodialysis patients, (e) a two-stent case, and (e) a case in which OCT examination was not performed after GW recrossing (Nagoshi et al., 2018) [1].
