Why a so high restenosis rate even with DES ?
Why a so high restenosis rate even with DES ? Hemodynamics perturbations insights

CONCLUSION
- Flow disturbances induced by a stent could be microscopic (between the strut pattern) or macroscopic.
- The flow disturbances are significant and participate to the restenosis process in the acute stage of the stent implantation.
- The enhancement of blood flow dynamics can decrease the restenosis rate (Pache, 2003, J. Am. Coll. of Cardiol. 41 and Kastrati, 2003, Circulation 103).
- Stenting of bifurcation site requires blood flow analysis to fully understand the in vivo investigations and to provide accurate recommendations for future developments.
