Usefulness of a 0.010-inch guidewire compatible balloon for crossing stent-jailed sidebranches

Failure of the balloon to pass through for a side branch in spite of wire crossing occasionally occurs due to a jailed stent during treatment of bifurcation lesions. In this report, we describe a novel 0.010-inch coronary guidewire compatible balloon (IKAZUCHI 10™ ) that is effective for crossing a side branch through the jailed stent strut, while another standard 0.014-inch guidewire compatible small balloon was unable to cross the same lesion. This novel 0.010-inch guidewire compatible balloon may be useful for a side branch that is difficult to cross through the stent strut.
