Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

5. Target lesion is located within or distal to a >60 degree bend in the vessel
6. Target lesion involves a bifurcation with a diseased (>50% stenotic)branch vessel >2.0 mm in diameter
7. Target lesion is totally occluded (TIMI flow<1) at baseline
8. Angiographic presence of probable or definite thrombus
9. Pre-treatment of the target vessel at the index procedure is not allowed with any device
10. A previously treated lesion within the target vessel:

* <15 mm from the target lesion (visual estimate)
* Performed </= 6 months from index procedure
* >30% residual stenosis after previous treatment
11. Predilation with a balloon catheter of the target lesion and/or target vessel is not allowed.

Summary
Brief summary
TAXUS ATLAS Direct Stent is a global, multi-center, single-arm, noninferiority trial comparing results from patients in whom the TAXUS Liberté stent was directly implanted (direct stenting) versus results from patients in whom implantation with the TAXUS Liberté stent was preceded by balloon angioplasty (pre-dilatation). The Control group consists of patients in the main TAXUS ATLAS trial, in which pre-dilatation was mandatory. The primary objective is to compare outcomes of direct stenting with balloon catheter pre-dilatation. The primary hypothesis is that late outcomes with direct stenting of the TAXUS™ Liberté Paclitaxel-Eluting Coronary Stent System will be non-inferior to conventional implantation with balloon catheter pre-dilatation
