Robotic magnetic-guided retrograde aortic ablation of atrioventricular nodal reentrant tachycardia in transposition of the great arteries after atrial switch

Abstract

Catheter ablation plays a key role in the management of supraventricular arrhythmias in patients with complete transposition of the great arteries (D-TGA) and atrial redirection surgery (ie, Mustard or Senning baffle), owing to their high prevalence, impact on quality of life and hospitalizations, and susceptibility to provoking malignant ventricular arrhythmias.1,2 There may be numerous challenges to safely and effectively eliminating culprit arrhythmias, including vascular abnormalities, baffle obstructions, calcified and rigid conduits that limit the feasibility and position of transbaffle punctures, and accurate localization of the atrioventricular (AV) conduction system to avoid collateral damage.
