Do additional anterior lesions at the right pulmonary veins prevent AF recurrence in patients undergoing PF ablation for atrial fibrillation?
A multiple procedure approach for PF ablation yields 86% arrhythmia-free survival, and additional anterior lesions at the right pulmonary veins may protect against recurrences.
PV reconnections are frequent in patients presenting for repeat ablations, especially at the anterior PV aspect. A multiple procedure approach estimates arrhythmia-free survival in 86% of patients. Procedures with additional anterior lesions at the right pulmonary veins (RPVs) could be protective for recurrences.
Eberl et al. (Fri,) studied this question.
