Wire perforation causing cardiopulmonary arrest during radiofrequency hot balloon ablation for pulmonary vein isolation.

ABSTRACT: A 73-year-old woman underwent radiofrequency hot balloon ablation (RHBA) for paroxysmal atrial fibrillation. After delivery into the left inferior pulmonary vein (LIPV), the guidewire perforated the venous wall. We injected contrast medium while the inflated balloon occluded the PV. Subsequently, bronchial-pulmonary venous fistula (BPVF) occurred and the severe hypoxia caused pulseless electrical activity (PEA). Cardiopulmonary resuscitation and intubation quickly recovered spontaneous circulation. She was initially treated by a multidisciplinary team in the intensive care unit and subsequently discharged without sequelae. Although relatively rare, there are some reports of wire perforation during RHBA and cryoballoon ablation. Some cases resolved after discontinuing anticoagulant therapy,
