Successful removal of a circular mapping catheter which perforated the pulmonary vein during cryoballoon ablation by lateral thoracotomy: a case report.

ABSTRACT:

Background

Serious complications may occur during cryoballoon ablation (CBA). However, pulmonary vein (PV) perforation by a circular mapping catheter and the strategy for removing the catheter remain poorly understood.

Case summary

A 40-year-old male presented with palpitations 2 years ago and was diagnosed with paroxysmal atrial fibrillation 5 months ago. He underwent CBA for paroxysmal atrial fibrillation. After isolation of the left PV, a circular mapping catheter was advanced in the right inferior pulmonary vein (RIPV), and single freeze was performed. After isolation of the PV, the catheter tip was immobile and could not be withdrawn with significant resistance. Computed tomography showed that the catheter tip perforated the posterior basal vein (V10) of the RIPV and re
