Rapid advancements in novel techniques, devices, and adjunctive pharmacotherapies have considerably reduced the risk of acute complications, restenosis, and stent thrombosis (ST), and ultimately have led to the extension of PCI’s clinical application for various complex bifurcation lesions. Moreover, interventional cardiologists have learned lessons from extensive clinical experiences in that many important anatomic features, including relative plaque distribution to the bifurcation, degree of SB angulation, and severity or length of SB lesion, should be taken into account for technical success and favorable clinical outcome.2 Considering that currently there are no clear guidelines to address the use of particular interventional techniques with regard to the specific anatomy of a given bifurcation lesion, every effort should be made to obtain understanding of the technical, clinical, and fundamental aspects of the management of bifurcation disease.
