Focal ISR according to angiographic classification of Mehran et al. (46). (A) ISR type IA: articulation or gap (black arrow is the ISR between the proximal and distal edges in white arrows); (B) ISR type IB: margin (black arrow is the ISR in correspondence of distal edge of stent between white arrows); (C) ISR type IC: focal body (black arrow is the ISR between the proximal and distal edges in white arrows); (D) ISR type ID: multifocal (black arrows highlight ISR at proximal and distal edge). ISR, in-stent restenosis.
