BTK lesions were associated with increased rates of perforation, slow flow and spasm which may be explained by more challenging procedural characteristics in these patients such as smaller vessel size and tortuosity. The higher incidence of emboli in ATK\/POP lesions is most likely attributed to the higher prevalence of severe calcium observed in this cohort. \u00a9 2015 Wiley Periodicals,
