The ostium of the left ante-rior descending artery (LAD) is one of the most difficult positions for CTO revasculari-zation. Until now, limited data has been made available for the prediction of successfulostial LAD CTO PCI. Objective: The aim of the study was to compare the differencesbetween ostial LAD and all other CTOs and to identify the predictors of successfulostial LAD CTO PCI. Methods: This retrospective analysis included consecutivepatients referred for CTO PCI between January 2001 and September 2013. Ostial LADCTO was defined as CTO at the position whose distance between lesion and left mainbifurcation was less than 1 mm. Baseline demographics, lesion characteristics, inter-ventional procedure details, and devices were compared between the ostial LAD groupand the all other CTOs group.
