Percutaneous treatment of coronary bifurcation lesions: a novel “extended Y” technique with complete lesion stent coverage: Figure 1

ifurcation lesions are one of the major unsolved problems of percutaneous coronary intervention (PCI). 2] However, none of these has been shown to be effective. We invented the ''extended Y'' technique, which uses conventional stent systems. In this technique, stenting of the main branch proximally and close to the origin of the side branch is followed by deployment of two kissing stents in a Y fashion in the distal branches, creating a short protrusion of a double stent barrel into the proximal stent. We studied this extended Y technique in bifurcations with disease of both the main branch and the two ostia of the distal branches.
