A U.S Post Approval Study Evaluating the SYNERGY XLV (MEGATRON) Stent System

Completed

• Conditions: Heart Diseases, Coronary; Cardiovascular Diseases; Atherosclerosis; Coronary Artery Disease

• Registration Number: NCT04807439
• Lead Sponsor: Boston Scientific Corporation

Brief Summary

This is a post-market, standard of care, real-world observational study to assess the clinical outcomes of the SYNERGY XLV (MEGATRON) Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 28 mm in length (by visual estimate) in native coronary arteries ≥3.50 mm to ≤5.00 mm in diameter (by visual estimate). This Post Approval study is a cohort associated with the Evolve 4.5/5.0 (SYNERGY LV) Post Approval Study, which is registered under ClinicalTrials.gov ID: NCT03875651.
