[Coronary intervention. 2012 update].

In-stent restenosis and stent thrombosis are still the main topics of any update on coronary intervention. One of the challenging issues in the past year lay in answering the question of whether the data on first-generation drug-eluting stents are still relevant in the light of newer stent designs and drugs. Other issues include new strategies in antiplatelet therapy, treatment of in-stent restenosis, particularly drug-eluting stent restenosis, treatment of multivessel and left-main disease, as well as the latest developments in bioresorbable polymers and "scaffolds". In the light of demographic changes, the main challenge for the interventional community is to build an evidence base for the adequate treatment of elderly patients in order to resolve uncertainties in the treatment of this challenging patient group.
