title: Mother-and-child technique using 4-Fr inner catheter for stent delivery during provisional stenting.
abstract: Provisional stenting is the most common strategy in the treatment of bifurcated lesions. However, such a situation as the failure in additional stent deployment to the side branch through the stent strut is occasionally encountered. In this paper, we report on two cases, in which we managed to successfully cross an additional stent to the angulated side branch through the stent strut using the four-in-six system after failed attempts using conventional techniques. This system will allow us to perform provisional stenting more easily.
