European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain BENCH & COMPUTATIONAL BIFURCATION STENT SIMULATIONS DK Crush vs tap. In vitro comparison of thrombogenicity and flow Author: Valeria Paradise, MD, Maasstad Hospital, Rotterdam, The Netherlands OBJECTIVE The purpose of the present study was to compare DKC vs TAP technique to evaluate their different effects in terms of strut apposition and thrombus formation in in-vitro models using OCT and computational flow reconstruction. METHODS N= 12 stents in total (Synergy n=6 and Ul(master=6) Bifurcation y-shaped model Stent with same platform were deployed using TAP or DKC technique Final POT was performed for all the experiments OCT pullback was performed from MV and SB before and after POT A peristaltic pump was used to perfuse the porcine blood through the silicone model at a flow rate of 200ml/min for 4 minutes Thrombus area was calculated from OCT pullback after perfusion CONCLUSION No difference in terms of stent struts apposition Similar acute thrombus formation POT significantly reduces EI Even when performed in silicon model, these procedures are associated with stent malapposition
