Cite This Study
Gardey et al. (2021) conducted a case report in Atypical twin atrioventricular nodal re-entrant tachycardia in congenitally corrected transposition of the great arteries (n=1). Catheter ablation of the inferior AV node was evaluated on Symptom recurrence. Catheter ablation of the inferior AV node successfully treated atypical twin AV nodal tachycardia, with the patient remaining asymptomatic without anti-arrhythmic drugs at 8 months.
