Strut Coverage With SYNERGY Stents and Bioresorbable Vascular Scaffold in Acute Myocardial Infarction

Not Applicable

Completed

• Conditions: Acute Coronary Syndrome

• Registration Number: NCT02890589
• Lead Sponsor: University Hospital, Toulouse

Brief Summary

To assess strut coverage in patients presenting an acute myocardial infarction and treated either with the SYNERGY stent or the Bioresorbable Vascular Scaffold, through a parallel group design.

Detailed Description

Single center, simple-blind randomized controlled trial, comparing the SYNERGY stent with the BVS device through a parallel group design.
