Following successful ablation of the left superior pulmonary vein (PV), the J-tip guidewire advanced into the left inferior PV and became completely entrapped. Venography demonstrated that, although the guidewire tip remained intravascular, a proximal segment appeared to course along the vessel wall, suggesting passage through an intraluminal structure. Multiple attempts at withdrawal using push-pull manoeuvres were unsuccessful. Repositioning with a radiofrequency ablation catheter also failed to release the entrapment. Given the risk of vessel rupture and major haemorrhage, the procedure was converted to general anaesthesia in a hybrid operating room with surgical standby. Bridge occlusion balloon-assisted extraction successfully released the entrapped guidewire without vascular injury. The retrieved guidewire had adherent fibrous white tissue, suggesting entrapment by a membranous pulmonary venous structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Balloon-assisted endovascular retrieval may represent a safe and less invasive alternative to surgical intervention for managing such entrapments.
