About

Chronic total coronary occlusions (CTO) have an especially high risk of angiographic restenosis, and need for new revascularization procedures. Drug-eluting coronary stents (DES) have demonstrated to significantly reduce the risk of restenosis and new revascularization procedures in comparison with bare-metal stents.

Most data on the efficacy of DES come from the sirolimus-eluting coronary stent Cypher (Cordis corp.), and paclitaxel-eluting coronary stent Taxus (Boston Sci.), and the Cypher stent is the only DES that has been randomly tested in CTO. Among second-generation DES, everolimus-eluting stent (EES) has shown excellent angiographic and clinical results, but this DES has not been studied in unfavourable scenario (such as CTO).

The aim of the CIBELES trial is to demonstrate the hypothesis that EES are equally effective in comparison with sirolimus-eluting stents in the treatment of CTO, in terms of angiographic efficacy considered as in-stent late lumen loss.

Inclusion criteria

Patients ≥ 18 year-old.
A total occlusion (TIMI 0-1) with an estimated time of occlusion > 2 weeks.
Symptomatic or silent ischaemia, or viable myocardium.
The occlusion is suitable for percutaneous coronary intervention.
The guidewire has crossed the occlusion, and the occlusion has been dilated with balloon or other device.

Exclusion criteria

Acute myocardial infarction in the myocardial area supplied by the target vessel within 2 weeks before the inclusion in the study.
The lesion can not be crossed with the guidewire and balloon angioplasty.
The vessel has been previously treated percutaneously.
The lesion is not suitable for a 2.25-3.5 coronary stent implantation.
The patient is not willing to undergo an angiographic follow-up.
The patient has contraindications for prolonged double (aspirin plus clopidogrel) anti-platelet therapy (e.g. allergy to aspirin, need for chronic oral anti-coagulation, or scheduled surgical intervention within 12 months.
Pregnancy or absence of pregnancy test in women of childbearing age.
Chronic renal failure (creatinine plasmatic values > 3.0 mg/dl).
Plasmatic platelet count < 100.000 mm-3 or > 700.000 mm-3.
The patient has a severe non-cardiac disease that limits his/her life expectancy to < 1 year.
The patient is currently included in other randomized trial.
