Rationale
• The occurrence of SFA in-stent restenosis (ISR) is high
• With stenting increasingly performed in the SFA, an increasing number of patients will require repeat treatment for ISR
• Currently there is no consensus about the treatment of choice
• Registry data indicate superiority of drug-eluting balloons
• 3 prospective randomized trials DCB vs. PTA(FAIR – In.Pact DCB, PEP: RS by DUS (core lab)PACUBA – Eurocor DCB, PEP: RS by diff. measurem. (no CL)COPA – Cotavance DCB, PEP: LLL by DSA (core lab)
• 1 Registry with historic control (DEBATE ISR, In.Pact DCB)

Conclusions
• First prospective randomized DCB study which shows a
reduced benefit of the DCB group after a certain time
• A delayed TLR after DCB might be driven
• By the underlying disease (ISR, calcium burden)
• By the DCB product
(different drug content over time in the vessel wall)
• First DCB study which shows a dose effect of DCB therapy
• Higher dose might be needed especially in complex SFA
lesions with higher chance of restenosis
