Why the study?
Catheter ablation of consecutive left atrial tachycardias (LAT) can be challenging, and data regarding pulsed field ablation (PFA) for LAT following prior catheter ablation of atrial fibrillation were lacking.
Is pulsed field ablation guided by ultra-high density mapping feasible and safe for treating consecutive left atrial tachycardias?
Is pulsed field ablation guided by ultra-high density mapping feasible and safe for treating consecutive left atrial tachycardias?
Pulsed field ablation is a feasible and safe modality for treating complex consecutive left atrial tachycardias, suggesting its utility may extend beyond standard atrial fibrillation ablation.

Hypothesis-generating for PFA in LAT; leaves open prospective validation before practice change.
