Cardiovascular outcomes after percutaneous coronary intervention on bifurcation lesions with moderate to severe coronary calcium: A single-center registry study.

Background: Both target vessel calcification and target vessel bifurcation are associated with worse outcomes following percutaneous coronary intervention (PCI). Whether these entities in combination interact to influence outcomes after PCI of complex coronary disease is not known.

Objectives: This study evaluated the association of target vessel bifurcation and target vessel calcification, alone and in combination, with adverse events following PCI.
