CONCLUSION

  1. In a non-diseased bifurcation model complex bifurcation techniques can be performed using the Magmaris scaffold with excellent angiographic results.
  2. Full bifurcation coverage and good scaffold expansion achieved
  3. Angiography and OCT are not able to detect the presence of strut fractures, as determined by micro-CT (the gold standard).
  4. Overall, in 9/25 procedures strut fractures identified, with no evidence of scaffold integrity compromise.
  5. Modified T stenting (mini-crush) is more challenging, need to ensure complete crush of the SB scaffold. Positioning paramount!
  6. Take care to avoid Longitudional Scaffold Deformity (LSD)
  7. Provisional stenting of the MV with additional TAP seems a reasonable approach.
