Abstract

Background: The aim of the study was to identify differences between proximal and distal cell rewir­ing with subsequent kissing balloon inflation (KBI) in the presence of a link connected to a carina on the jailed side branch ostium (SBO).

Methods: Kaname stents were deployed in bifurcation models (n = 12) with subsequent KBI and were confirmed by optical coherence tomography. The jailing configuration and cell rewiring were completely controlled and classified as follows: FC-Dist, free carina (no links connected to a carina) and distal cell re­wiring; CC-Prox, connected to a carina (the presence of a link connected to a central carina) and proximal cell rewiring; CC-Dist, connected to a carina and distal cell rewiring; and FarDist, far-distal cell rewiring.

Results: The number of frames with malapposed struts (MS) in the SBO was significantly smaller in the CC-Prox group than in the CC-Dist group (26.7 ± 1.5 and 39.7 ± 0.6, respectively, p < 0.05). The number of frames with MS continuously present from the distal end to the proximal side of the SBO was significantly smaller in the CC-Prox group than in the CC-Dist group (17.0 ± 2.0 and 36.7 ± ± 5.8, respectively, p < 0.05). The ratio of the maximal opened stent cell area to the SBO area was significantly larger in the CC-Prox group than in the CC-Dist group (64.2 ± 1.2% and 38.8 ± 5.6%, respectively, p < 0.05).

Conclusions: This study showed that in cases with a link connected to a carina, fewer malapposed struts may be present in proximal cell rewiring with subsequent KBI than in distal cell rewiring.
