Successful catheter ablation of postoperative atrial tachycardia with
conduction disturbances: assessment by late-gadolinium enhancement
magnetic resonance imaging and high-resolution electro-anatomical
mapping
Abstract
Atrial tachycardia (AT) in the right atrium often occurs following
open-heart surgery. Catheter ablation for these AT is challenging and
can lead to unintended conduction block. We performed late-gadolinium
enhancement magnetic resonance imaging prior to catheter ablation and
predicted wavefront propagation during SR as well as the slow conduction
zone
