PUROPSE

  1. To investigate flow distributions of the LCx ostium after KBT and to compare local flow dynamics influenced by the locations of jailed struts using a left main bifurcated model.
  2. To investigate influences of non-KBT on local flow dynamics in the vicinity of overlaying stent struts at the flow tract of the LCx ostium.

SUMMARY AND TAKE HOME MESSAGES

  1. Jailed struts locally yielded slow flow regions behind the struts.
  2. Without KBT, abnormal larger slow flow region was present behind the struts over the cardiac cycle, which may be a potential cause of thrombus formation or fibrin deposition, and eventually induce neointimal formation there.
  3. Further studies for finding techniques or developing devices are expected for pursuing ideal LM bifurcation stenting.
