ABSTRACT
<p><b>BACKGROUND</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
