Trial Outcomes & Findings for Endeavor Zotarolimus - Eluting Stent in the Treatment Lesions in Small Native Coronary Arteries. (NCT NCT00609947)

NCT ID: NCT00609947

Last Updated: 2015-02-09

Results Overview

In-segment percent diameter stenosis at 8 months post-procedure with percent diameter stenosis defined as the value calculated as 100 x (RVD - Minimal Lumen Diameter (MLD)/RVD using the mean values from two orthogonal views (when possible) by Qualitative Coronary Angiography (QCA).

Participant Flow

Subjects were recruited by local and regional medical centers from December 21, 2007 through November 22, 2010.

Subjects were excluded from participation if they did not meet inclusion/exclusion criteria and fall into the category of per protocol small vessel stenting - 2.25mm, 2.5mm and 2.75mm - single or multi-vessel (Rev K).

PRIMARY outcome

Timeframe: 8 months post-procedure

Population: The primary analysis sample consisted of 176 subjects (ITT) including the first 97 subjects with 2.25 mm, 39 subjects with 2.50 mm and 40 subjects with 2.75mm stents who met the study entry criteria, signed the written informed consent, and were enrolled in the trial.

In-segment percent diameter stenosis at 8 months post-procedure with percent diameter stenosis defined as the value calculated as 100 x (RVD - Minimal Lumen Diameter (MLD)/RVD using the mean values from two orthogonal views (when possible) by Qualitative Coronary Angiography (QCA).

PRIMARY outcome

Timeframe: 12 months post-procedure

Population: 12-month MACE Rate was compared to a 20% performance goal. * 1st 97 subjects enrolled and implanted with 2.25mm stents * 1st 39 subjects enrolled and implanted with 2.5mm stents * 1st 40 subjects enrolled and implanted with 2.75mm stents * A supplemental safety analysis group of subjects with 2.25mm stents N=38 (included in 2.25mm group N=135)

Major Adverse Cardiac Events rate at 12 months post-procedure defined as death, target-vessel Myocardial Infarction (Q wave and non-Q wave), emergent cardiac bypass surgery, or target lesion revascularization, repeat percutaneous transluminal coronary angioplasty or cardiac bypass surgery.
