Transient Left Atrial Appendage Inversion During Transcatheter Closure Device Placement

Abstract

A 72-year-old female patient underwent left atrial appendage closure. During recapture of the occlusion device, transient inversion of the appendageal wall occurred. We describe the mechanism with real-time imaging and share our experience of handling this situation. To the best of our knowledge, this is the first case report of this unique recapture complication.

Intraoperative Inversion of the Left Atrial Appendage Following Ligation

“… 3 , 6 Direct traction on LAA tissue with devices during cardiac procedures can also produce inversion. 7 While inversion is most common in the intraoperative period with CPB, any source of negative pressure can theoretically invert the LAA. For instance, multiple cases have been reported after left ventricular assist device implantation.…”
