7. Conclusion
Patients with localized left atrial LVAs had whole left atrial
electrophysiological degeneration as assessed by regional mean regional
voltages and total left atrial conduction velocity. In addition, whole
left atrial electrophysiological degeneration parameters were well
associated with AF recurrence. These findings suggest that localized LVA
is an excellent maker of AF substrate, but may not always be an optimal
ablation target.
