The U.S. FDA has granted breakthrough device designation for Bioventrix Inc.’s Revivent Tc Transcatheter Ventricular Enhancement System for heart failure following a heart attack. The system is designed to exclude scar tissue that has formed on the left ventricle in a procedure that is less invasive than current medical options and better than drug therapy, allowing healthy heart tissue to function more efficiently. The left ventricle is the heart’s pumping chamber, and scarring can prevent it from contracting and providing the steady circulation of blood that the body needs.
