In the present case, migration was observed 18 months post-procedure, representing an unusually late presentation. Notably, surgical retrieval demonstrated complete circumferential endothelialization of the device, confirming true long-term tissue incorporation before subsequent erosion and detachment. Furthermore, serial early and mid-term imaging consistently showed a stable device position, making early malposition or technical error an unlikely cause. This constellation of findings underscores the rarity of very late mechanical destabilization after an initially successful device closure.<\/jats:p>","DOI":"10.3389\/fcvm.2026.1807603","type":"journal-article","created":{"date-parts":[[2026,4,20]],"date-time":"2026-04-20T05:24:26Z","timestamp":1776662666000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
