Percutaneous Retrieval of an Entrapped Ablation Catheter during a Retrograde Approach for a Left Free Wall Accessory Pathway

Hung-Kai Huang, Li-Wei Lo,

Abstract

A 25-year-old man suffered from repeated attacks of orthodromic atrioventricular reciprocating tachycardia utilizing a left lateral accessory pathway (AP) for retrograde conduction. The catheter was approached through the aorta to map the AP and was entrapped in the mitral valve apparatus, and it had a broken internal wire. A snareassisted technique was successfully utilized to retrieve the catheter.
