Key result
Catheter ablation successfully terminated atrial flutter in a patient with an unrepaired univentricular heart, followed by sinus rhythm and second-degree AV block requiring a pacemaker.
Case Report (n=1)
Catheter ablation of atrial flutter can be successfully performed in adults with complex, unrepaired univentricular congenital heart disease using advanced electroanatomical mapping.

Supports ablation feasibility in unrepaired univentricular CHD; leaves open conduction block risk and need for prospective data.
Ortiz-Ávalos et al. (2024) conducted a case report in Atrial flutter in a univentricular heart (n=1). Catheter ablation was evaluated on Arrhythmia termination. Catheter ablation successfully terminated atrial flutter in a patient with an unrepaired univentricular heart, followed by sinus rhythm and second-degree AV block requiring a pacemaker.
