In view of the potential risks of using DCB alone in the treatment of de novo bifurcation lesions, the following 2 treatment strategies are available. (1) DCB combined with provisional DES implantation 1-2 mm distally to the lesion ostium whenever this was required (DCB+pDES strategy). (2) DES implantation 1-2 mm distally to the lesion ostium followed by DCB (DES+DCB strategy).
