DES Versus BiOSS LIM - POLBOS II Study

Coronary bifurcation lesions pose therapeutic problems during percutaneous coronary interventions (PCI) and are associated with higher rates of periprocedural complications as well as higher rates of in-stent restenosis and stent thrombosis. Provisional T-stenting (PTS) is the best treatment strategy at the moment. However, the optimal approach to coronary bifurcations treatment is still a subject of debate, especially when the side branch is large, not easily accessible and narrowed by a long lesion. One of the proposed alternatives are dedicated bifurcation stents (DBS). However, there is large scarcity of randomized trials with DBS. POLBOS II study is continuation of POLBOS I (POLish Bifurcation Optimal Stenting) study, in which paclitaxel-eluting stent BiOSS Expert® (Balton, Poland) was assessed. Now performance of sirolimus-eluting stent BiOSS LIM® (Balton, Poland) is verified.
