The widespread and capricious distribution of focal fibrillation waves suggests transmural conduction is the likely mechanism in persistent atrial fibrillation.
The incidence and appearance of focal fibrillation waves on the right and left atrial epicardial surface were visualized during 10 seconds of persistent atrial fibrillation in a 71-year-old woman with valvular heart disease. The frequent, nonrepetitive, widespread, and capricious distribution of focal waves suggests that transmural conduction of fibrillation waves is most likely the mechanism underlying focal fibrillation waves.

Lanters et al. (2015) conducted a case report in Persistent atrial fibrillation and valvular heart disease (n=1). Visualization of focal fibrillation waves was evaluated on Incidence and appearance of focal fibrillation waves. Visualization of focal fibrillation waves revealed a frequent, nonrepetitive, widespread distribution, suggesting transmural conduction as the underlying mechanism.
