Does radiofrequency catheter ablation of the AV junction from the left ventricle achieve AV block in patients with unsuccessful right-sided ablation?
Left ventricular radiofrequency ablation of the AV junction is an effective and safe alternative when the conventional right-sided approach fails.
Sousa et al. (1991) conducted an observational in Refractory tachyarrhythmias with failed right-sided AV junction ablation (n=8). Radiofrequency catheter ablation of the AV junction from the left ventricle was evaluated on Induction of third-degree AV block. Radiofrequency catheter ablation of the AV junction from the left ventricle successfully induced third-degree AV block in 100% (8/8) of patients after failed conventional right-sided approaches.
