Rethinking overdilation of drug-eluting stents: An effective 'loose end'

摘要

Percutaneous coronary interventions (PCI) with the implantation of a drug-eluting stent (DES) for either bifurcation or non-bifurcation lesions are associated with a dramatic reduction of the need for revas-cularisation when compared to a bare metal stent implantation1'2. During the procedure, overdilation is frequently required to achieve full apposition, although there is no consensus with respect to the degree of extensive post-dilation in real-world international practice. To this end, a timely bench-test study focusing on the impact of overdilation on stent maximal expansion capacity and deformation appears in this issue of Eurolntervention.
