3D-OCT New implications of optimal SB re-crossing

Author: Yoshinobu Onuma, MD, PhD, Horax Centre, Erasmus MC, Rotterdam, The Netherlands

 

BACKGROUND

  • With advent of the new-generation OCT/OFDI system (C7/8 LightLab, OFDI Terumo) with a high frame rate (100-180fps) and fast pull-back speed (20-40mm/s), 3- dimensional reconstruction of OCT became feasible due to elimination of motion artefacts.
  • 3-dimensional OCT reconstruction gives us better understanding of complex coronary anatomy such as bifurcation, compared to the conventional 2-D OCT.

CONCLUSION

  • In 2009-2010, with advance of OCT/OFDI technology, 3D-reconstruction became feasible. In 2011-2013, the potential of the technology was demonstrated in off- line 3D-OCT with manual strut detection.
  • In bifurcation, 3D-OCT may guide positioning of the wire through the appropriate (distal) cell. The early study suggests that such a guidance strategy reduced the incidence of malapposition in bifurcation.
  • In 2014, the on-line 3D OCT/OFDI with automatic strut detection is available. The equipped “real-time” 3D OFDI will help utilization of 3D in clinical situation.
