Why the study?
The clinical role of left atrial hypertension in patients with AF and its predictive value in those undergoing pulmonary vein isolation remains unknown.

LA hypertension may identify higher recurrence risk after PVI; leaves open whether pressure-guided ablation improves outcomes.
Does left atrial pressure predict atrial fibrillation recurrence in patients undergoing pulmonary vein isolation?
Elevated left atrial pressure (>15 mmHg) is an independent predictor of atrial fibrillation recurrence following pulmonary vein isolation.
