Key result
Catheter ablation of focal atrial tachycardias arising from the atrial appendages and aortic sinuses of Valsalva has a high success rate, though specific anatomic considerations are important.
Catheter ablation is a highly successful treatment for focal atrial tachycardias originating from the atrial appendages and aortic sinuses of Valsalva, requiring careful anatomic consideration.
May support ablation for these focal ATs with anatomic caution; leaves open prospective validation of outcomes.
Focal atrial tachycardias arising from the atrial appendages and the aortic sinuses of Valsalva are less frequently encountered in clinical practice. This review article describes the clinical presentation, surface P wave morphology, electrophysiologic characteristics and treatment of these arrhythmias. Catheter ablation of these focal tachycardias has a high success rate. It is however important to be aware of specific anatomic considerations in these locations for optimal treatment outcomes with low complication rates.

Taylor et al. (2014) conducted a review in Focal atrial tachycardias arising from the atrial appendages and the aortic sinuses of Valsalva. Catheter ablation was evaluated. Catheter ablation of focal atrial tachycardias arising from the atrial appendages and aortic sinuses of Valsalva has a high success rate, though specific anatomic considerations are important.
