Zusammenfassung: | Background:Recrossing the compromised side branch (SB) with a balloon is sometimes technically challenging.The aim of this study was to evaluate whether in-stent anchoring (ISA) is safe and effective to facilitate SB balloon delivery for final kissing.Methods:One hundred and fifty-nine consecutive patients were included (166 bifurcation lesions) in this prospective,single-center registry.ISA was used as a bailout method after unsuccessful SB crossing using conventional techniques,including low-profile balloons.Technique success was defined as SB balloon delivery and final kissing.Results:Kissing-balloon delivery was successfully performed with conventional strategies in 149 of 166 lesions (89.8%).In the remaining 17 lesions (10.2%),recrossing of the main vessel stent strut was not successful;therefore,ISA was attempted.The balloon successfully crossed the stent struts,and final kissing was achieved in 15 of 17 lesions (88.2%).Total final kissing was achieved in 164 of 166 lesions (98.8%),with success rates of 100% in the single-stent group and 97.6% in the two-stent group.Two cases without balloon delivery had complex bifurcation lesions with severe calcification.There was no vessel dissection in the anchoring zone.Conclusions:ISA is safe and effective for recrossing stent struts when conventional low-profile balloons have failed.However,large-scale trials are warranted for further evaluation. |
