Key result
Radiofrequency catheter ablation of AV nodal reentry tachycardia was performed in a patient with transposition of the great arteries after Mustard correction using an electroanatomical map.
Case Report (n=1)
Provides an anatomical perspective and procedural strategy for performing radiofrequency ablation of AVNRT in patients with complex congenital heart disease post-Mustard correction.
Feasibility shown in single post-Mustard TGA case; leaves open systematic evaluation before broader adoption.
A case of radiofrequency catheter ablation of atrioventricular (AV) nodal reentry tachycardia, in a patient with transposition of the great arteries after venous rerouting according to Mustard, is described. An electroanatomical map of the His and AV nodal region was created from inside the systemic venous atrium. Retrograde mapping of the pulmonary venous atrium was performed and the arterial catheter retracted to a position in close proximity to the venous catheter inside the intraatrial baffle. This position was chosen to deliver radiofrequency current.

Jongbloed et al. (2010) conducted a case report in Atrioventricular nodal reentry tachycardia in a patient with transposition of the great arteries after Mustard correction (n=1). Radiofrequency catheter ablation was evaluated. Radiofrequency catheter ablation of AV nodal reentry tachycardia was performed in a patient with transposition of the great arteries after Mustard correction using an electroanatomical map.
