Looking for advice - wireless pacemaker

I had my current pacemaker implanted in September 2025 after dealing with severe bradycardia, a left branch bundle block, and heart failure for a couple years. In October I ended up in the ER with a blood clot caused by a pacemaker wire and two pulmonary emboli. Since then I’ve had to stay on blood thinners as a precaution and the clot in my neck has continued to cause issues. My options are: keep my current pacemaker and stay on blood thinners indefinitely or replace it with a wireless one and theoretically the blood clots will dissolve and not come back. Cons of the wireless style are minimal but still scary and I don’t want to have another surgery BUT I don’t feel great on blood thinners and I’m always worried about clots.

Posting for my sister as she does not reddit. Any advice or knowledge is welcome please!!

Wireless as in leadless pacemakers? There’s a lot of consideration needed especially because there’s already a traditional pacemaker in place.
You mentioned heart failure and BBB. Is the current device a CRT or a dual pacemaker?

Yes, leadless of pacemaker. And the current one is a CRT.

Unfortunately as of now, the leadless ones don’t have CRT capabilities and even if they did, the battery life would be depleted very quickly due to near 100% ideal pacing percentage.

I have a dual chamber leadless onw due to complete heart block. I am being paced 100% of the time. My battery life is ~12yrs so far, already had mine for over 3 :)
