Catheter Ablation of Peri‐AV Nodal Atrial Tachycardia from the Noncoronary Cusp of the Aortic Valve
Why the study?
Does catheter ablation from the noncoronary cusp safely and effectively eliminate peri-AV nodal atrial tachycardia in patients with symptomatic focal AT?

Implication
Supports NCC ablation for peri-AV nodal AT; hypothesis-generating from small case series and should not yet change practice.
Structured PICO
Does catheter ablation from the noncoronary cusp safely and effectively eliminate peri-AV nodal atrial tachycardia in patients with symptomatic focal AT?
P
Population
10 patients with symptomatic focal atrial tachycardia where the point of earliest right atrial activation was at the peri-AV nodal region, just postero-superior to the His-bundle (identified from a broader cohort of 54 patients undergoing invasive electrophysiological evaluation).
I
Intervention
Catheter ablation using radiofrequency or cryothermal energy delivered from within the base of the noncoronary aortic valve cusp (NCC) via a retrograde aortic approach.
O
Outcome
Successful elimination of the arrhythmia and long-term arrhythmia-free survival.
Catheter ablation from within the base of the noncoronary cusp is a safe and effective strategy for eliminating focal atrial tachycardias originating from the high-risk peri-AV nodal region.
