Key result
A previously ligated left atrial appendage can still cause clinical events, such as a transient ischemic attack, due to thrombus formation at the stump.
Highlights the risk of thrombus formation and subsequent clinical events at the stump of a previously ligated left atrial appendage.
Answers are grounded in this paper and cite their sources.
Raises caution for residual thromboembolic risk post-LAA ligation; hypothesis-generating for prospective stump surveillance studies.
We present a 71-year-old female patient with transient ischaemic attack. A thrombus located at the stump of previously ligated left atrial appendage was suspected as the cause of event.
