Factors for Side Branch Occlusion

  • Carina displacement is probably the main mechanism for SB compromise/closure and this may be predicted(!!!)
  • Negative deviation from expected SB ostial stenosis aswell as SB MLD are associated with SB closure
  • Several predictors of negative difference (SB MLD, plaque length ratio MV/MB and MB/SB diameterratio) were identified together with the importance of MV – SB distal angle α value
  • The link between carina displacement and SB closure isangle alpha, with cut-off value for high closure riskbelow 40 degrees
