Persistent Flow Into the Left Atrial Appendage after Suture and Stapler Exclusion
(A) The left atrial appendage has been excluded by closing off the orifice of the appendage cavity from the atrium by sutures. There is a color flow jet observed between the atrium and the appendage suggesting persistent flow and communication. (B) The left atrial appendage remains attached to the atrium and has been excluded by stapling. However, there is persistent flow in the appendage demonstrated by color Doppler, suggesting persistent communication between the atrium and the appendage.
