Strategies to Mitigate Coronary Stent Migration Post-Percutaneous Coronary Intervention (PCI)

Implantation of cardiovascular stents has surfaced as a forefront to treat coronary artery diseases through Percutaneous Coronary Intervention (PCI). However, stent migration is a significant complication that arises in a subset of patients, potentially leading to fatal outcomes. Current strategies including self-expanding stents, drug-eluting coatings, and imaging-guided placement are evaluated alongside emerging innovations like high-density lipoprotein (HDL)-infused coatings, 3D printing, and biodegradable stent materials. This review examines underlying mechanisms of stent migration, focusing on patient-specific, procedural, and design-related factors. By addressing stent migration, this research aims to enhance patient outcomes and advance the efficacy of PCI interventions.
