A provisional strategy for treating true bifurcation lesions employing a scoring balloon for the side branch: final results of the AGILITY trial.

Background: The provisional approach for bifurcation stenting with side-branch balloon angioplasty is associated with dissections and suboptimal results requiring kissing balloon techniques or bailout stenting. We hypothesized that using a scoring balloon for the side branch and a drug-eluting stent for the main vessel might improve outcomes of true bifurcation lesions.

Methods And Results: A total of 93 patients with complex bifurcations were enrolled in a multicenter, single-arm, prospective clinical trial.

A randomized, controlled, multi-center trial comparing the safety and efficacy of zotarolimus-eluting and paclitaxel-eluting stents in de novo lesions in coronary arteries: final results of the ZoMaxx II trial.

Background/objectives: The purpose of this prospective, randomized, single-blind controlled clinical trial was to compare the effectiveness of a zotarolimus-eluting stent (ZoMaxx™) with a paclitaxel-eluting coronary stent (Taxus™ Express(2)™) in patients with angina pectoris and a single native coronary artery lesion between 10-28 mm in length and 2.5-3.75mm in diameter.

Long-term benefit of the TAXUS Liberté stent in small vessels and long lesions. TAXUS ATLAS program.

Background: The long-term impact of treating de novo coronary lesions in native vessels and challenging small vessel and long lesion subsets with TAXUS Liberté stents is unknown. This report examines the 3-year efficacy and safety from the TAXUS ATLAS program.

Methods And Results: TAXUS ATLAS WH, Small Vessel, and Long Lesion are non-randomized studies comparing TAXUS Liberté (n = 871), TAXUS Liberté 2.

Comparison of vascular response to zotarolimus-eluting stent vs paclitaxel-eluting stent implantation: pooled IVUS results from the ZoMaxx I and II trials.

Background: The ZoMaxx I and II trials were randomized controlled studies of the zotarolimus-eluting, phosphorylcholine-coated, TriMaxx stent for the treatment of de novo coronary lesions. The aim of this study was to compare the vessel response between zotarolimus- (ZES) and paclitaxel-eluting stents (PES) using intravascular ultrasound (IVUS).

Methods And Results: Data were obtained from the ZoMaxx I and II trials, in which a standard IVUS parameter was available in 263 cases (baseline and 9-months follow up).

TAXUS Liberté attenuates the risk of restenosis in patients with medically treated diabetes mellitus: results from the TAXUS ATLAS program.

Objectives: The aim of this study was to assess the relative efficacy and safety of the second-generation TAXUS Liberté paclitaxel-eluting stent (PES) in patients with and without diabetes mellitus.

Background: Diabetic patients suffer from accelerated atherosclerosis and increased risk of restenosis after coronary interventions; however, prior data suggest that PES might blunt this effect, providing equal benefit in diabetic and nondiabetic patients.

Methods: A pooled analysis of all 4 TAXUS ATLAS studies was conducted that included 413 diabetic and 1,116 nondiabetic subjects treated with the TAXUS Liberté stent for de novo coronary lesions.

Reduced risk of restenosis in small vessels and reduced risk of myocardial infarction in long lesions with the new thin-strut TAXUS Liberté stent: 1-year results from the TAXUS ATLAS program.

Objectives: The TAXUS ATLAS Small Vessel (SV) and Long Lesion (LL) multicenter studies compared the performance of the thin-strut (0.0038 inch) TAXUS Liberté 2.25-mm stent (Boston Scientific; Natick, Massachusetts) and the TAXUS Liberté 38-mm long stent (Boston Scientific; Natick, Massachusetts) with the earlier paclitaxel-eluting TAXUS Express (Boston Scientific) stent that has identical polymer, drug dosage, and release kinetics but different stent geometry and thicker struts (0.

Two-year clinical outcomes after paclitaxel-eluting stent or brachytherapy treatment for bare metal stent restenosis: the TAXUS V ISR trial.

Aims: This study sought to investigate the 2-year outcomes of patients treated with the paclitaxel-eluting TAXUS((R)) stent (PES) or vascular brachytherapy (VBT), the previous 'gold standard therapy', for bare metal stent in-stent restenosis (ISR).

Methods And Results: In the TAXUS V-ISR trial, 396 patients with bare metal stent ISR referred for percutaneous coronary intervention were prospectively randomized to either PES or beta source VBT. The present analysis reports 24-month clinical outcomes from that study.

Polymer-based, paclitaxel-eluting TAXUS Liberté stent in de novo lesions: the pivotal TAXUS ATLAS trial.

Objectives: The goal of this research was to assess non-inferiority of the next-generation TAXUS Liberté stent (Boston Scientific Corp., Natick, Massachusetts) versus the TAXUS Express stent (Boston Scientific Corp.).

Comparison of the efficacy of direct coronary stenting with sirolimus-eluting stents versus stenting with predilation by intravascular ultrasound imaging (from the DIRECT trial).

A direct coronary stenting technique using drug-eluting stents may decrease drug-eluting stent efficacy due to possible damage to the surface coating of the stent. The DIRECT is a multicenter, prospective, nonrandomized trial designed to evaluate the direct stenting strategy for the sirolimus-eluting Bx-Velocity stent compared with the historical control (SIRIUS trial, stenting with predilation). Volumetric and cross-sectional intravascular ultrasound analyses at 8-month follow-up were performed in 115 patients (DIRECT n= 64, control n = 51).

Paclitaxel-eluting stents vs vascular brachytherapy for in-stent restenosis within bare-metal stents: the TAXUS V ISR randomized trial.

Context: Restenosis within bare-metal stents is often treated with repeat percutaneous coronary intervention, although subsequent recurrence rates are high, with vascular brachytherapy (VBT) affording the best results. The effectiveness of drug-eluting stents in this setting has not been established.

Objective: To investigate the safety and efficacy of the polymer-based, slow-release paclitaxel-eluting stent in patients with restenotic lesions after prior stent implantation in native coronary arteries.

Comparison of a polymer-based paclitaxel-eluting stent with a bare metal stent in patients with complex coronary artery disease: a randomized controlled trial.

Context: Compared with bare metal stents, drug-eluting stents reduce restenosis in noncomplex lesions. The utility of drug-eluting stents has not been evaluated in more difficult stenoses.

Objective: To investigate the safety and efficacy of the polymer-based, slow-release paclitaxel-eluting stent in a patient population with more complex lesions than previously studied.
