Introduction
Some patients fail to respond to
persistent
atrial fibrillation (PeAF) catheter ablation in spite of multiple
procedures and ablation strategies, including low voltage area
(LVA)-guided, linear, and
complex
fractionated atrial electrogram (CFAE)-guided ablation procedures. We
hypothesized that LVA extent could predict non-response to PeAF catheter
ablation in spite of multiple procedures.
