: Pulmonary vein isolation (PVI), by catheter ablation, represents the current treatment for drug-resistant atrial fibrillation (AF). Nowadays cryoballoon (CB) is a recognized ablation method in patients with atrial fibrillation, mainly due to its ease of use, leading to reproducible and fast procedures. This novel single shot technology literally revolutionized the approach to AF ablation. : The historical development of the cryoballoon, ablation techniques and new approaches beyond the ordinary PVI and complications are summarized here. : Although cryoballoon ablation has greatly standardized the approach to PVI a few critical points still need to be clarified scientifically in order to further uniform this procedure in cath labs worldwide. Duration and dosage of the cryoapplication is undoubtedly a topic of great interest.
经导管消融的肺静脉隔离术（PVI）是目前治疗药物抵抗性心房颤动（AF）的方法。目前，冷冻球囊（CB）消融在房颤患者中是一种公认的消融方法，主要是因为其易于使用，可实现可重复和快速的手术。这种新型的单次消融技术真正改变了房颤消融的方法。本文总结了冷冻球囊的历史发展、消融技术和超越普通 PVI 的新方法以及并发症。尽管冷冻球囊消融大大规范了 PVI 的方法，但仍有一些关键问题需要从科学上进一步澄清，以便在全球导管实验室进一步统一这一程序。冷冻球囊的应用时间和剂量无疑是一个非常有趣的话题。
