SUNNYVALE, Calif., Oct. 25, 2023 /PRNewswire/ -- EBR Systems, Inc. (ASX:EBR), the medical device company developing wireless cardiac pacing systems, is proud to announce that positive results from the first completely leadless cardiac resynchronization therapy (CRT) in the United States have been published in The Journal of American College of Cardiology (JACC).

The positive results published in JACC are based on a 1-year follow-up of the first-in-human implantation in the US of totally leadless CRT pacing utilizing the Micra™ leadless pacing system in the right ventricle in conjunction with EBR's investigational WiSE® CRT Electrode in the left ventricle of the heart. At 12-months, the patient showed improved heart failure symptoms (NYHA Class III to II), no recurrent heart failure-related hospitalization, a reduction in QRS duration, and an improvement in left ventricular ejection fraction (LVEF) from 30% to 65%.

This first use in the US of the WiSE CRT System as a first-line therapy is a future market expansion opportunity for EBR. The initial addressable market of $2.6 billion is focused on treating patients who had previously failed CRT and by treating new CRT patients, the addressable market could increase to $6.8 billion......
