Greater distance between ablation lines reduces the recurrence rate after pulmonary vein isolation.
Pulmonary vein isolation (PVI) is a recommended strategy for rhythm control in atrial fibrillation (AF), but its success rate remains unsatisfactory. Continuous research is being conducted to explore new technologies and modifications to the existing ablation workflow in order to reduce the arrhythmia recurrence rate. ⋯ Close distance between PVI lines contributes to AF recurrence; thus, increasing the DBL and ensuring a higher DBL/TD ratio may be an advantageous ablation strategy.

Pulmonary Vein Isolation With or Without Left Atrial Appendage Ligation in Atrial Fibrillation: The aMAZE Randomized Clinical Trial.
Left atrial appendage elimination may improve catheter ablation outcomes for atrial fibrillation. ⋯ Percutaneous left atrial appendage ligation adjunctive to pulmonary vein isolation did not meet prespecified efficacy criteria for freedom from atrial arrhythmias at 12 months compared with pulmonary vein isolation alone for patients with nonparoxysmal atrial fibrillation, but met prespecified safety criteria and demonstrated high rates of closure at 12 months.

[Atrial fibrillation in the elderly - the geriatric perspective].
Atrial fibrillation is the most common cardiac arrhythmia in older adults. As a result of the positive data on ablation, the focus has shifted to rhythm control. The method of choice is pulmonary vein isolation. ⋯ Oral anticoagulation remains an essential component of pharmacological therapy for atrial fibrillation. Older adults require an individualised treatment approach, which should be based on current guidelines and complementary tools. The assessment of functionality should be taken into account in therapy and goal planning.
