Key result
Review outlines the pathophysiology, risk factors, and management of stent restenosis affecting ~10% of PCIs.
Why the study?
Intracoronary stent restenosis complicates around 10% of PCI procedures, presenting distinct mechanistic and diagnostic challenges depending on stent type.
This review provides a comprehensive overview and proposed management algorithm for intracoronary stent restenosis, a complication affecting approximately 10% of PCI procedures.
May aid recognition of post-PCI restenosis; leaves open validation of proposed management algorithms.
INTRODUCTION: Despite advances in stent technology for percutaneous coronary intervention (PCI) in the treatment of coronary disease, these procedures can be complicated by stent failure manifested as intracoronary stent restenosis (ISR). Even with advances in stent technology and medical therapy, this complication is reported to affect around 10% of all percutaneous coronary intervention (PCI) procedures. Depending on stent type (drug-eluting versus bare metal), ISR has subtle differences in mechanism and timing and offers different challenges in diagnosing etiology and subsequent treatment options. AREAS COVERED: This review will be visiting the definition, pathophysiology, and risk factors of ISR. EXPERT OPINION: The evidence behind management options has been illustrated with the aid of real life clinical cases and summarized in a proposed management algorithm.

Protty et al. (2023) conducted a review in Intracoronary stent restenosis (ISR). Management of intracoronary stent restenosis was evaluated. This review summarizes the definition, pathophysiology, risk factors, and management options for intracoronary stent restenosis, a complication affecting around 10% of all PCI procedures.
