Simple vs complex approaches for bifurcation stenting strut apposition by OCT

Author: Carlo Di Mario, MD, Imperial College London, UK

 

CONCLUSION

  • Malapposition in bifurcational stenting is very frequent in the quadrants facing the origin of the side-branch
  • Lesions treated with 2 Stents have more frequent strut malapposition than lesions treated with 1 stent with a significant difference in the proximal segment and in the quadrants opposite to SB opening
  • Lesions treated with 1 Stent also have very frequent malapposition and the clinical significance of the difference with 2 stents is difficult to explore in a small series
  • Clinical outcome was not influenced by the presence/severity of malapposition

LIMITATIONS

  • Lesions treated with 2 Stents have worse baseline characteristics including more severe and longer SB stenoses
  • Lesions treated with 2 Stents have larger SB diameter, with greater potential for malapposition.
  • Only two techniques of double stenting assessed
  • Analysis limited only to main vessel
  • OCT used as documentary final imaging and not for procedural guidance
