@gloaming Many thanks for extensive reply, including personal history. And yes, I fully realize you're not medically trained, but you have more knowledge on the topic(s) than I do, hence I reached out. A couple of additional pieces of information I should have included.

First, I had atrial flutter, not AF (but related), and my EP told me after the ablation that once he had dealt with my atrial flutter tissue, he tried to stimulate AF several times, with no success (bad wording on my part, I know), which he seemed quite happy about.

Second, in November 2025, I had a TRANSTHORACIC ECHO (TTE) COMPLETE which indicated an ascending aorta aneurism had grown from 4.3cm in September 2024 to 4.7cm.

Third, my cariologist is putting me in touch with a thoracic surgeon (but no appointment has been scheduled yet). Thus, the reason he appeared to be less concerned about the PACs. My opinion only.

Lastly, before I sent the message to you and Mayo CC this morning, I sent a message via portal to my EP group about the PACs. Unsure if they were aware of the aneurism, but they are now.

Thanks again.
