CONCLUSION

  • If you want to do PCI for angiographically significant SB
    • Acknowledge that the side branch is different from the main branch.
    • Assess the clinical relevance (myocardial mass at risk >10% by MPIestimation) of the side branch first.
  • If you still want to do
    • Remind that there can be discrepancy between anatomical severity and physiological severity. When doubtful, measure FFR (Adequate experience and knowledge is required).
    • Consider the possibility that the side branch is naturally protected.
  • If you still want to do
    • Do it (very) well and be ready to use IVUS or OCT.
