Quantitative angiographic methods for bifurcation lesions : A consensus statement from the European Bifurcation Group

The treatment of bifurcation lesions is complex and increasingly common. A growing number of dedicated bifurcation devices are under clinical evaluation, but no standardized methodology exists. Specifically, the angiographic analysis of bifurcation lesions is not standardized and current QCA packages are not designed for bifurcation lesions. This consensus statement outlines the limitations of conventional QCA in the bifurcation application, and outlines a new standard approach for the analysis and reporting of the angiographic results of the bifurcation lesion allowing for future trial and device comparisons and mechanistic insight into location and modes of treatment failure.
