This video shows a questionable floating structure at the lateral wall of the left atrial appendage. This video was shown at the German echocardiography congress in Cologne (EKK) in 2011 as part of a contrast workshop. The participants rated this video as follows:
- a normal left atrial appendage, cardioversion allowed: 2 %
- a dilated left atrial appendage with a little spontaneous echo contrast , cardioversion allowed:11%
- diagnosis doubtful , thrombus possible, cardioversion deferred: 48%
- thrombus in the left atrial appendage, cardioversion deferred: 35%
The contrast enhanced images reveal a thrombus at the base of the left atrial appendage (black contrast free structure). |
