Coronary bifurcation lesion interventions account for 15%-20% of all percutaneous coronary interventions and represent one of the most challenging lesions in interventional cardiology. Several coronary bifurcation classification systems have been proposed, including Lefevre,1 Medina,2 Mohaved,3 and DINO4 classification. Medina classification has become the most accepted classification system due to its simplicity. However, it does not include additional lesion characteristics such as bifurcation site, main and side branch vessel sizes, lesion length, and bifurcation angle, which are crucial characteristics of a bifurcation definition. Moreover, such additional lesion characteristics may help decision-making regarding stenting technique and device selection.
