About the Revivent System

The BioVentrix Revivent System is designed to support a less invasive procedure to treat a dilated left ventricle of patients with ischemic heart failure with reduced ejection fraction (HFrEF) and extensive left ventricular scar, who have a suboptimal response to guideline-directed medical therapy. The procedure uses myocardial micro-anchor implants to reconstruct the dilated left ventricle to produce a more efficient chamber. Prior trials showed statistical significance with a subpopulation for similar endpoints to those that will be assessed in the RELIVE Trial. The Revivent System received the CE Mark in 2016.
