A 50-year-old man with paroxysmal atrial fibrillation underwent pulmonary vein isolation (PVI) using a cryoballoon. During the PVI procedure, a circular diagnostic catheter (CDC) was wedged deeply into the right PV (RPV). The lung tissues seemed to be tightening around the CDC. After various attempts to resolve the situation, the shaft of the CDC was completely torn, and the circular part remained in the RPV. At a follow-up of three months, the patient showed neither atrial fibrillation events nor clinical symptoms. We herein report a broken CDC shaft during PVI with a cryoballoon, which has not yet been reported.
一名患有阵发性心房颤动的50岁男性接受了使用冷冻球囊的肺静脉隔离术（PVI）。在PVI手术过程中，一根环形诊断导管（CDC）深深楔入右肺静脉（RPV）。肺组织似乎在紧紧包裹着CDC。在尝试了各种方法来解决这种情况后，CDC的导管轴完全撕裂，环形部分留在了RPV中。在三个月的随访中，患者既没有发生心房颤动事件，也没有临床症状。我们在此报告了一例在使用冷冻球囊进行PVI时发生的CDC导管轴断裂事件，这尚未见报道。
