Key result
Complete left atrial posterior wall isolation on top of pulmonary vein isolation resulted in 80% of patients being free from atrial arrhythmia recurrences after an average follow-up of 16 months.
Why the study?
Does complete isolation of the LA posterior wall on top of PVI prevent atrial arrhythmia recurrences in patients with persistent or long-standing persistent AF?
Observational (n=25)
No

Hypothesis-generating for posterior wall isolation in persistent AF; randomized trials needed before practice change.
Saad et al. (2014) conducted an observational in Persistent or longstanding persistent atrial fibrillation (n=25). Complete isolation of the left atrial posterior wall (Box Lesion) plus pulmonary vein isolation was evaluated on Freedom from any atrial arrhythmia recurrences. Complete left atrial posterior wall isolation on top of pulmonary vein isolation resulted in 80% of patients being free from atrial arrhythmia recurrences after an average follow-up of 16 months.
