The change in circulating galectin-3 predicts absence of atrial fibrillation after thoracoscopic surgical ablation

Abstract

The change of circulating Gal-3, rather than its baseline value, predicts AF recurrence after thoracoscopic ablation. Patients in whom Gal-3 increases after ablation have a high recurrence rate reflecting ongoing profibrotic signalling, irrespective of arrhythmia continuation.
