Values are % (n/N). *The composite safety endpoint is a composite of freedom from device- and procedure-related mortality within 30 days, and freedom from major target limb amputation and freedom from CD-TLR within 9 months after the index procedure. CD-TLR is defined as any TLR of the target lesion with restenosis >70% (confirmed by angiography) associated with at least one of the following: reoccurrence of ischaemic rest pain, worsening of pre-existing wounds, or occurrence of a new wound(s). Major adverse events defined as a composite of all-cause mortality, major target limb amputation, and CD-TLR. §Mechanically driven TLR is defined as any TLR due to a flow-limiting dissection or flow-limiting thrombosis at the target lesion that occurs within 37 days post procedure documented by a peak systolic velocity ratio >2.4. CD-TVR is defined as any TVR of the target vessel associated with at least one of the following: reoccurrence of ischaemic rest pain, worsening of pre-existing wounds, or occurrence of a new wound(s). CD-TLR: clinically driven target lesion revascularisation; CD-TVR: clinically driven target vessel revascularisation; DCB: drug-coated balloon; PTA; percutaneous transluminal angioplasty; TLR: target lesion revascularisation; TVR: target vessel revascularisation
