Speech Bubble Sign—Insights Regarding Incomplete Left Atrial Appendage Closure via Electrocardiography-Synchronized Computed Tomography in Robotic Surgery Cases
Incomplete LAA closure occurred in 24% of cases despite direct visualization using robotics. Anatomical factors likely contribute more than technique alone. For high-risk patients with long-standing AF, techniques such as lumen crushing or external clips may enhance closure success. Further refinements are needed to improve the reliability of internal LAA closure methods.
