PUROPSE
- 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.
- 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
- Jailed struts locally yielded slow flow regions behind the struts.
- 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.
- Further studies for finding techniques or developing devices are expected for pursuing ideal LM bifurcation stenting.
