Conclusions
LAVI ≥ 30 mL/m2 may provide a simple, intuitive, and clinical meaningful risk stratification for development of AF after CTI AFL ablation. The utility of elevated LAVI in patients undergoing typical AFL ablation to identify patients most likely to benefit from prophylactic PVI or more intensive monitoring prior to discontinuation of anticoagulation requires further evaluation.
