Background: Cutting balloons are commonly used for the preparation of calcified lesions, but problems with crossability occasionally limit the use of these balloons. A novel cutting balloon was recently developed and reported to have improved crossability in clinical settings. However, the predictors of its unsuccessful crossing have been unclear. The aims of this study were to examine the delivery success rate and to identify the predictors of unsuccessful crossing with the novel cutting balloon.
