ABSTRACT
Objective To investigate the differences of various two-stent techniques in vitro and virtual bench testing. Methods Stent implantation with classic crush, double kissing ( DK) crush and culotte stenting techniques were performed in the silicone simulation model of bifurcation vessels with various distal bifurcation angles. The whole processes were recorded by a micro-focus camera. Results Distal side branch (SB) re-crossing in classical crush technique left a significant gap without stent coverage near the carina in T type bifurcation model after final kissing balloon inflation (FKBI) . The gap was also noted in either classic crush with proximal SB re-crossing or DK crush with two times proximal SB re-crossing in T type bifurcation model. The size of the gap in DK crush technique was smaller than that of classic crush. In Y type bifurcation model, both DK crush and culotte stenting left no gap compared to T type bifurcation model. Two times proximal SB re-crossing in culotte stenting resulted in a new stent carina formation after FKBI. Conclusions Distal bifurcation angle was an anatomatic predictor of gap formation in two-stent technique. In T type bifurcation model, the size of gap in DK crush technique was smaller than that of classic crush. It was suggested to perform two times proximal SB re-crossing for DK crush technique and distal SB re-crossing for culotte stenting.
