One-Year Results of the LIBERTY 360 Study: Evaluation of Acute and Midterm Clinical Outcomes of Peripheral Endovascular Device Interventions.

Purpose: To report the 1-year results of a multicenter study of peripheral artery disease (PAD) treatment with a variety of endovascular treatment strategies employed in routine practice.

Materials And Methods: The LIBERTY trial ( ClinicalTrials.gov identifier NCT01855412) is a prospective, observational, core laboratory-assessed, multicenter study of endovascular device intervention in 1204 subjects (mean age 69.

Impact of calcification on percutaneous coronary intervention: MACE-Trial 1-year results.

Objectives: The Multi-center Prospective Study to Evaluate Outcomes of Moderate to Severely Calcified Coronary Lesions (MACE-Trial) was designed to provide further insight on the impact of calcification on procedural and long-term percutaneous coronary intervention outcomes.

Background: Prior studies evaluating the impact of lesion calcification on percutaneous coronary intervention outcomes are limited by: retrospective nature, pooled data from multiple studies, or lack of specificity around calcification with only operator assessment and without core lab evaluation.

Methods: The MACE-Trial was a prospective, multicenter, observational clinical study that enrolled 350 subjects at 33 sites from September 2013 to September 2015.
