POLBOS LM: POLish Bifurcation Optimal Treatment Strategy Study for Left Main Bifurcation Percutaneous Coronary Intervention (PCI)
Study Details
Study Description
Brief Summary
The primary objective of this study is to study the safety and efficacy of the BiOSS LIM C with respect to Patient oriented Composite Endpoint (PoCE) at 12 months in a "real world" left-main bifurcation population and as compared with a prespecified performance goal.

|---|---|
| Experimental: BiOSS LIM C The treatment strategy consists of contemporary PCI of the left-main bifurcation, using the BiOSS LIM C stent system, following diagnostic angiography demonstrating significant distal unprotected left main disease and local Heart Team discussion applying the anatomic SYNTAX Score. |
Device: BiOSS LIM C
The BiOSS LIM C (Bifurcation Optimization Stent System, Balton, Warsaw, Poland). The BiOSS LIM C is a dedicated bifurcation stent covered with a mixture of a biodegradable polymer and the antiproliferative substance sirolimus. BiOSS LIM C will be used for treatment of the Left-Main bifurcation, according to its instructions for use.
The Alex-Plus cobaltchromium sirolimus eluting stent (Balton, Warsaw, Poland) will be used for treatment of distal left-main side branches according to its instructions for use (i.e. proximal segments of the left anterior descending and left circumflex arteries as well as the ramus intermedius if the latter vessel is part of a trifurcation).
All other lesions (other than left-main bifurcations) will be treated with XIENCE family everolimus-eluting coronary stent systems.

Outcome Measures
Primary Outcome Measures
- Non-inferiority comparison of Patient-oriented composite endpoint (PoCE) of BiOSS LIM C to a pre-specified objective performance goal (OPC). [12 months]
POCE defined as a composite measure of: All-cause mortality, Stroke (Modified Ranking Scale (mRS) ≥1), Any Myocardial infarction (MI) (includes non target vessel territory), Any unplanned revascularization for ischemia (includes all target and nontarget vessels). OPC based on data collected in Excel-study
Secondary Outcome Measures
- POCE defined as composite of all-cause death, stroke, any MI, and any revascularization [30 days; 6 months]
- Target Vessel Failure defined as cardiac death, Target vessel MI, and clinically indicated target vessel revascularization [30 days; 6 months; 12 months]
- Target Lesion Failure (device oriented composite endpoint) defined as cardiac death, target vessel MI, and clinically indicated target lesion revascularization [30 days; 6 months ; 12 months]
- Mortality [30 days; 6 months; 12 months]
- Stroke [30 days; 6 months; 12 months]
- Myocardial infarction [30 days; 6 months; 12 months]
- Revascularization [30 days; 6 months; 12 months]
- Stent thrombosis according to Academic Research Consortium classification [30 days; 6 months; 12 months]
