Prediction of side branch occlusion in bifurcational lesions during percutaneous coronary interventions by preprocedural coronary computed tomography using the CT bifurcation score.

Introduction: Coronary computed tomographic angiography (CCTA) is a highly diagnostically accurate non-invasive imaging method for a thorough evaluation of atherosclerotic plaques. Many CCTA-based imaging investigations concentrate on bifurcation lesions.

Aim: To determine whether intraprocedural side branch (SB) obstruction during the percutaneous coronary intervention (PCI) of lesions involving bifurcations might be predicted by preprocedural CCTA.
