Atrial Tachycardia From an Unusual site-Left Atrial Appendage Tachycardia: Challenges in Ablation

S A Deshpande et al. J Postgrad Med.

Abstract

Left atrial appendage (LAA) tachycardia are rarely encountered in clinical practice (2.1% of focal atrial tachycardia). Out of these, the ones arising from the distal part of LAA are difficult to ablate due to higher risk of LAA perforation and thromboembolism. We hereby present a patient with LAA tachycardia mapped to the tip of LAA with the help of the CARTO system and ablated. This case highlights the inherent challenges faced in such a scenario.

Keywords: Appendage ablation; CARTO; atrial tachycardia; left atrial appendage.
