Key Result
Percutaneous epicardial mapping and ablation successfully treated two patients with focal atrial tachycardias arising from the left atrial appendage following failed endocardial approaches.
Structured PICO
Does percutaneous epicardial mapping and ablation cure focal atrial tachycardias arising from the left atrial appendage after failed endocardial approach?
P
Population
2 patients with ectopic atrial tachycardias arising from the left atrial appendage following failure of a conventional endocardial approach
I
Intervention
Minimally invasive percutaneous epicardial mapping and ablation
O
Outcome
Successful ablation/cure
Percutaneous epicardial mapping and ablation may be a viable approach for focal atrial tachycardias originating from the left atrial appendage when conventional endocardial ablation fails.

Abstract
Focal atrial tachycardias originating from the left atrial appendage present unique anatomic challenges for successful ablation. We describe the role of minimally invasive percutaneous epicardial mapping and ablation in the management of two patients with ectopic atrial tachycardias arising from the left atrial appendage following failure of a conventional endocardial approach to achieve cure.
