Ablation of non-pulmonary vein triggers from predictable sites is an important step to improve outcomes in atrial fibrillation ablation, either empirically or after observing significant ectopy.
Does ablation of non-pulmonary vein triggers improve outcomes in patients undergoing atrial fibrillation ablation?
This review highlights the importance and approaches for mapping and ablating non-pulmonary vein triggers to improve outcomes in atrial fibrillation ablation.
Ablation of non-pulmonary vein (PV) triggers is an important step to improve outcomes in atrial fibrillation ablation. Non-pulmonary vein triggers typically originates from predictable sites (such as the left atrial posterior wall, superior vena cava, coronary sinus, interatrial septum, and crest terminalis), and these areas can be ablated either empirically or after observing significant ectopy (with or without drug challenge). In this review, we will focus on ablation of non-PV triggers, summarizing the existing evidence and our current approach for their mapping and ablation.
Gianni et al. (2018) conducted a review in Atrial fibrillation. Ablation of non-pulmonary vein triggers was evaluated. Ablation of non-pulmonary vein triggers from predictable sites is an important step to improve outcomes in atrial fibrillation ablation, either empirically or after observing significant ectopy.
