Key result
In patients with atrial fibrillation and fibrotic atrial cardiomyopathy, PVI plus box isolation of fibrotic areas achieved single and multiple procedure success rates of 69% and 83% at 16 months.
Why the study?
Does pulmonary vein isolation supplemented with box isolation of fibrotic areas improve outcomes in atrial fibrillation patients with fibrotic atrial cardiomyopathy?
Cohort (n=92)
Does pulmonary vein isolation supplemented with box isolation of fibrotic areas improve outcomes in atrial fibrillation patients with fibrotic atrial cardiomyopathy?
In AF patients with fibrotic atrial cardiomyopathy, supplementing PVI with box isolation of fibrotic areas achieves 83% multiple-procedure success, though extensive fibrosis predicts worse outcomes.

Supports adjunctive box isolation in fibrotic AF; leaves open superiority over PVI alone pending randomized trials.
Schreiber et al. (2017) conducted a cohort in Atrial fibrillation with fibrotic atrial cardiomyopathy (n=92). Pulmonary vein isolation plus box isolation of fibrotic areas (PVI + BIFA) was evaluated on Single and multiple procedure success. In patients with atrial fibrillation and fibrotic atrial cardiomyopathy, PVI plus box isolation of fibrotic areas achieved single and multiple procedure success rates of 69% and 83% at 16 months.
