Role of oral anticoagulants in treating atrial fibrillation after pulmonary vein ablation

Atrial fibrillation (AF) is the commonest arrhythmia seen by cardiologists in day-to-day practice. Risk factors for AF include age, hypertension, diabetes mellitus, obesity, and smoking (1). Oral medications are commonly given to prevent clot formation and to control heart rate and rhythm. Other options include ablation, pulmonary vein isolation (PVI), pacemaker, maze procedure, and bypass surgery. These patients are at a high risk of developing stroke. A study was carried out to investigate the role of anticoagulants after PVI was performed to treat atrial fibrillation.
