Cryoballoon ablation of focal atrial tachycardia originating from right atrial appendage: Case report and review of the literature
Why the study?
Catheter ablation of focal AT from the RAA can fail due to anatomical difficulty and complication risks, sometimes requiring alternative tools when RF ablation is unsuccessful.
Can cryoballoon ablation successfully treat focal atrial tachycardia originating from the right atrial appendage when radiofrequency ablation fails?

Implication
May offer an alternative for refractory RAA tachycardia; leaves open need for prospective validation.
Structured PICO
Can cryoballoon ablation successfully treat focal atrial tachycardia originating from the right atrial appendage when radiofrequency ablation fails?
P
Population
A patient with focal atrial tachycardia originating from the right atrial appendage (RAA) that was not terminated by radiofrequency ablation
I
Intervention
Cryoballoon ablation
O
Outcome
Successful ablation of RAA tachycardia
Cryoballoon ablation may serve as an effective alternative for treating focal atrial tachycardia originating from the right atrial appendage when conventional radiofrequency ablation fails.
