Prospective Study to Assess DES Re-endothelization in BMS Restenosis and De-novo Lesions (DESERT)

July 22, 2013 updated by: Andrea Picchi, S.M. Misericordia Hospital

Des Re-Endothelization for In-StEnt ResTenosis. The DESERT Study

The hypothesis of this study is that strut coverage occurs earlier when a DES is implanted to treat a BMS restenosis compared with atherosclerotic de-novo lesion. This hypothesis is supported by two different observations: first, when a DES is implanted to treat a BMS restenosis, stent struts are deployed and drugs are eluted on a soft tissue mostly characterized by extracellular matrix with a regular surface. In this case stent malposition is less likely to occur compared to atherosclerotic lesion whose surface is often more irregular and rich in calcium. Second, patients who develop in-stent restenosis after BMS implantation are likely to show a more pronounced neointima hyperplasia and, when a DES is implanted to treat restenosis, reendothelialization is likely to occur earlier. If this hypothesis was verified, duration of dual antiplatelet therapy could be shortened after DES implantation on BMS restenosis with a clinical advantage in terms of bleeding risk. Furthermore, a higher bleeding risk is often a reason for choosing a BMS instead of a DES; thus, patients presenting with BMS restenosis are likely to have a higher bleeding risk and to benefit from a shorter period of dual antiplatelet therapy.
