6-year results of BiOSS stents in coronary bifurcation treatment.

Background: The wide variation in bifurcation anatomy has generated an ongoing search for stents explicitly designed for coronary bifurcations, and to date, results have been underachieved.

Methods: The POLBOS I and POLBOS II were international, multicentre, randomized, open-label, controlled trials. Patients were randomly assigned to BiOSS Expert (in POLBOS I, biodegradable polymer eluting paclitaxel)/BiOSS LIM (in POLBOS II, biodegradable polymer eluting sirolimus) stent implantation or regular drug-eluting stent (rDES) deployment.

Angiographic Restenosis in Coronary Bifurcations Treatment with Regular Drug Eluting Stents and Dedicated Bifurcation Drug-Eluting BiOSS Stents: Analysis Based on Randomized POLBOS I and POLBOS II Studies.

Aim: The marked variation in bifurcation anatomy has brought about an ongoing search for stents specifically constructed for coronary bifurcations. This study aimed to analyze the angiographic restenosis prevalence and patterns and predictors of different patterns in dedicated bifurcation BiOSS® vs. current generation drug-eluting stents implanted in coronary bifurcation lesions based on data from two clinical trials POLBOS I and II.

Comparison of dedicated BIOSS bifurcation stents with regular drug-eluting stents for coronary artery bifurcated lesions: Pooled analysis from two randomized studies.

Background: Coronary bifurcation treatment poses a therapeutic challenge. The aim of this study was to analyze pooled data of two randomized clinical trials, POLBOS I and POLBOS II, to compare 1-year follow-up results and identify possible prognostic factors.

Methods: In POLBOS trials dedicated bifurcation BiOSS® stents were compared with regular drug eluting stents (rDES) in patients with stable coronary artery disease or non ST-segment elevation acute coronary syndrome (POLBOS I: paclitaxel eluting BiOSS® Expert vs.

Regular drug-eluting stents versus the dedicated coronary bifurcation sirolimus-eluting BiOSS LIM® stent: the randomised, multicentre, open-label, controlled POLBOS II trial.

Aims: The aim of the POLBOS II randomised trial was to compare any regular drug-eluting stents (rDES) with the dedicated bifurcation sirolimus-eluting stent BiOSS LIM for the treatment of coronary bifurcation lesions. The secondary aim was to study the effect of final kissing balloon inflation (FKBI) on clinical outcomes.

Methods And Results: Between December 2012 and December 2013, 202 patients with stable coronary artery disease or non-ST-segment elevation acute coronary syndrome were randomly assigned 1:1 to treatment of the coronary bifurcation lesions either with the BiOSS LIM stent (n=102) or with an rDES (n=100).

Regular Drug-Eluting Stent vs Dedicated Coronary Bifurcation BiOSS Expert Stent: Multicenter Open-Label Randomized Controlled POLBOS I Trial.

Background: Results of regular drug-eluting stents (rDESs) in bifurcation treatment are not optimal. The aim of the Polish Bifurcation Optimal Stenting I (POLBOS I) trial was to compare bifurcation treatment with any rDES vs the dedicated bifurcation paclitaxel-eluting stent BiOSS Expert (Balton, Poland). The second aim was to study the effect of final kissing balloon (FKB) inflation on clinical outcomes.

Dedicated paclitaxel-eluting bifurcation stent BiOSS® (bifurcation optimisation stent system): 12-month results from a prospective registry of consecutive all-comers population.

Aims: Dedicated bifurcation stents seem to be the most promising solution for treating bifurcations. The aim of our study was to present the 12 months results of a new dedicated stent for coronary bifurcation lesions -the paclitaxel-eluting stent- BiOSS® Expert (Bifurcation Optimisation Stent System, Balton, Warsaw, Poland).

Methods And Results: Sixty-three patients with 65 lesions were enrolled in the registry.

First-in-man study of paclitaxel-eluting stent BiOSS (Bifurcation Optimisation Stent System) dedicated for coronary bifurcation stenoses: three months results.

Background: The best treatment strategy for coronary bifurcation stenosis is still unknown. Dedicated bifurcation stents are the most promising solution.

Aim: To evaluate the safety and short-term efficacy of a new stent dedicated for coronary bifurcation stenosis.

The carina angle-new geometrical parameter associated with periprocedural side branch compromise and the long-term results in coronary bifurcation lesions with main vessel stenting only.

Background: The two main problems unresolved in coronary bifurcation stenting are periprocedural side branch compromise and higher restenosis at long term. The purpose of this study is to reveal the link between periprocedural side branch compromise and long-term results after main vessel stenting only in coronary bifurcations.

Methods: Eighty-four patients formed the study population.
