Key result
Pulmonary vein antrum isolation significantly decreased left atrial size in patients with atrial fibrillation.
Why the study?
Does Pulmonary vein antrum isolation reduce left atrial size in patients with AF?
Does Pulmonary vein antrum isolation reduce left atrial size in patients with AF?
Pulmonary vein antrum isolation leads to structural reverse remodeling of the left atrium, though this decrease in size does not correlate with freedom from AF recurrence.

LA size reduction after PVAI in AF lacks correlation with recurrence; extends prior observational remodeling data but remains hypothesis-generating.
