8. Inflow arteries are free from hemodynamically significant obstruction (i.e. ≥ 50% diameter stenosis). It is allowed to treat inflow lesions during the index-procedure if the result is ≤ 30% diameter stenosis (treatment with DCB or DES is not allowed). Treatment of a non-target lesion in the target vessel is allowed if the nontarget lesion is considered to be an inflow lesion.
