Percutaneous coronary intervention (PCI) of bifurcation lesions remain one of the most technically challenging areas in interventional cardiology. Careful planning and execution are needed to preserve main vessel and side branch patency, with evolving evidence guiding the choice between provisional and two-stent strategies, and between individual techniques. This narrative review, which represents the first installment of a two-part series, synthesizes current knowledge on bifurcation PCI, detailing the anatomical classifications, lesion assessment tools, procedural planning, and execution of techniques including T and Protrusion (TAP), double-kissing (DK) crush, mini-crush, culotte, V-stent, and emerging modifications. We contextualize the choice of strategy within lesion complexity, procedural goals, and patient-specific considerations. This review is intended as a visual, practical, technique-focused reference for interventionalists and interventional trainees involved in the management of bifurcation lesions.
