Reply to comment by Aanar in Georgia doctor implants one of the first wireless, dual chamber pacemakers: New type of pacemaker is safer option than traditional surgery by universityofga
Definitely. At least for the Micra, which is the only cordless in general use here we mostly use it for the most frail patients where we worry if the surgery of a regular pacemaker will be an issue or that the skin will heal properly if they have barely any body fat. If not for the price it'd probably be more popular, but even then we wouldn't recommend it if there were a chance of the patient outliving the battery.
The article says he implanted it in a 64 year old woman, which imo is way too young unless they plan to be able to remove it(doesn't look like it)
I'm curious how this is supposed to be a dual chamber pm though? Being cordless would almost by definition mean only having direct contact with the right ventricle. I'm wondering if it is just like the Micra av that tries to sense the atrial contraction to synchronize. That's not really dual chamber though. The article doesn't specify and I'm not very familiar with Abbott's cordless models.
Edit: looking up the aveir, it looks like they actually use 2 individual devices, one for right atrium and one for right ventricle, which communicates wirelessly. Neat. Also they wrote that it's designed to be extractable, which is nice i guess, but it is never unproblematic to remove something screwed into the heart. There is a reason leads are not rarely left even if they could be extracted.
