This document discusses distal embolic protection devices used during percutaneous coronary interventions (PCI) of saphenous vein grafts. It provides background on how embolization of plaque debris can cause no-reflow and increased biomarkers. Three main devices are described - the Guardwire balloon occlusion catheter, the Filterwire embolic protection filter, and the Spider filter. Clinical trial results for each device showing reductions in major adverse cardiac events compared to no protection are presented. Tips for using each device safely and effectively are also provided. The document concludes with recommendations from guidelines supporting the use of embolic protection devices when technically feasible for saphenous vein graft PCI.
