The fluid dynamics in two different stent configurations, peak-to-valley (S1) and peak-to-peak (S2),udwithin a fully expanded situation and a 30% restenosis, is investigated. Numerical simulations areudcarried out in order to evaluate the conditions promoting atherosclerotic events when a selfexpandingudbare metal stents (SE-BMS) is applied. The conclusions are that the two configurations,udS1 and S2, have a similar fluid dynamic behavior, as far as the WSS is concerned, but OSI and RRTudmaps suggest that the peak-to-peak configuration, S2, has a better behavior than the peak-to-valleyudone, S1.
