Key result
Ablation at the tip of the left atrial appendage successfully treated arrhythmias in 4 cases following the failure of both endocardial and epicardial mapping and ablation.
Why the study?
Does ablation at the tip of the left atrial appendage result in successful ablation in patients with arrhythmias who failed standard endocardial and epicardial approaches?
Does ablation at the tip of the left atrial appendage result in successful ablation in patients with arrhythmias who failed standard endocardial and epicardial approaches?
The tip of the left atrial appendage can be an unusual but successful site for ablation in patients with arrhythmias who have failed standard endocardial and epicardial approaches.
Should not yet alter practice in refractory arrhythmias; leaves open the role of LAA tip ablation pending controlled studies.
Left Atrial Appendage Tip. Uncommon sites of ablation for arrhythmias can be the cause of failed ablations. This series includes 4 cases requiring ablation at the tip of the left atrial appendage after both endocardial and epicardial mapping and ablation failed.
