Stent Fracture Classification Methods

TypePopma et al. (45)Allie et al. (44)Scheinert et al. (46)
1Single-strut fracture or gap between struts >2 times normalSingle-strut fracture onlyMinor: single-strut fracture
2Multiple strut fractures with V-form division of stentMultiple single-stent fractures occurring at different sitesModerate: fracture >1 strut
3Complete transverse stent fracture without displacement of fractured fragments >1 mm during cardiac cycleMultiple single-stent fractures resulting in complete transverse linear fracture but without stent displacementSevere: complete separation of stent segments
4Complete transverse stent fracture with abundant movement and displacement of fractured fragments >1 mm during cardiac cycleComplete transverse linear type 3 fracture with stent displacement
