1 Over 200,000 patients worldwide are estimated to receive a CRT device each year. However, limitations prevent some patients from benefiting. CHALLENGING PROCEDURE 5% implanted patients fail to have coronary sinus (CS) lead in a single procedure 1,2,3 EFFICACY RATE 30% patients who receive a CRT device don t benefit from treatment 4,5,6 EBR Systems, Inc. 686 W. Maude Ave., Suite 102 Sunnyvale, CA USA POST IMPLANT COMPLICATIONS 10% patients experience CS lead complications including lead dislodgements and phrenic nerve stimulation 1,2,7,8,9 UPGRADES 23% patients who receive a CRT device already have a conventional pacemaker or ICD implanted 10.
