Abstract:
Pulmonary vein isolation (PVI) is the mainstay of every atrial fibrillation (AF) ablation procedure. However, it is still debated in the literature whether PVI alone is sufficient to achieve long-term freedom from atrial tachyarrhythmias in patients with non-paroxysmal AF. Hereby, we discuss the hypothetical clinical scenario of a patient with AF relapse 6 months after PVI in whom all pulmonary veins are electrically silent at the time of repeat ablation.
