CorMatrix Cor™ PATCH for epicardial infarct repair

Contemporary management of ischemic heart disease lacks strategies to directly access the heart and promote reparative cellular mechanisms to improve postinfarct cardiac remodeling. Epicardial infarct repair (EIR) is an emerging technique whereby bioactive materials are sewn over ischemic areas of the heart at the time of surgical revascularization to promote adaptive cardiac repair. The CorMatrix Cor (TM) PATCH (CorMatrix Cardiovascular Inc., GA, USA) is an acellular bioactive material compatible with EIR. Herein, we review current preclinical and clinical data for the CorMatrix Cor PATCH and its use in EIR. Lay abstract Therapies for heart attacks include revascularization and medical therapy, but clinicians lack methods of stimulating cells to improve cardiac repair and reduce cardiac fibrosis. Epicardial infarct repair (EIR) is an emerging technique where biomaterials are sewn over areas of the heart damaged by heart attacks. These materials have properties to stimulate repair at a cellular level. This procedure can be performed by cardiac surgeons during coronary artery bypass surgery. The CorMatrix Cor (TM) PATCH (CorMatrix Cardiovascular Inc., GA, USA) is a biomaterial compatible with EIR. Herein, we review the CorMatrix Cor PATCH and discuss its use in EIR.
