DES Versus BiOSS LIM - POLBOS II Study

Summary

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.
