Key result
Radiofrequency ablation through a retrograde approach successfully eliminated ectopic atrial tachycardias in 11 of 12 patients, with no recurrences during 14 ± 8 months of follow-up.
Why the study?
Does radiofrequency ablation through a retrograde approach prevent tachycardia recurrence in patients with ectopic atrial tachycardias and early activation at the His site?
Population
12 patients with ectopic atrial tachycardias (EAT) and early atrial activation at the His site.

May support retrograde ablation for select per-Hisian EAT; hypothesis-generating and should not yet change practice.

Does radiofrequency ablation through a retrograde approach prevent tachycardia recurrence in patients with ectopic atrial tachycardias and early activation at the His site?
Radiofrequency ablation via a retrograde approach is a safe and effective strategy for treating ectopic atrial tachycardias originating near the His bundle, specifically from the non-coronary aortic sinus or mitral annulus.
Kriatselis et al. (2008) conducted an observational in Ectopic atrial tachycardias (EATs) with early atrial activation at the His site (n=12). Radiofrequency (RF) ablation through a retrograde approach was evaluated on Tachycardia elimination and recurrence. Radiofrequency ablation through a retrograde approach successfully eliminated ectopic atrial tachycardias in 11 of 12 patients, with no recurrences during 14 ± 8 months of follow-up.
