Catheter ablation is the most effective treatment for atrial fibrillation (AF). Electrical pulmonary veins isolation (PVI) forms the cornerstone ablation strategy. Radiofrequency (RF) in combination with 3D mapping system is the traditional ablation approach to treat AF. As a single-shot ablation system, cryoballoon (CB) has been an established ablation modality to facilitate PVI procedure. As a novel non-thermal single-shot ablation technology, pulsed field ablation (PFA) has its unique biophysical profile. Recent studies have demonstrated that PFA allows for efficient and durable PVI. However, the manipulation of single-shot ablation catheter may be different from the conventional point-bypoint RF ablation catheter; ablation catheter with fixed size may have practical difficulties in variable anatomy and different clinical scenarios. The present article focuses on the technical aspects, describes the procedural approaches and illustrates the practical techniques of using CB and PFA for PVI, ultimately with the purpose to facilitate the ablation procedure and improve the patients’ clinical outcome.
