The Role of Noncoronary Cusp Ablation Approach in the Treatment of Perinodal Atrial Tachycardias
Key result
Among patients with perinodal focal atrial tachycardias, 25% required ablation in the noncoronary aortic cusp, with no clinical or electrophysiological clues predicting the true original site.
Why the study?
Do clinical and electrophysiological properties predict the need for noncoronary aortic cusp (NCC) ablation in patients with perinodal atrial tachycardias?

Implication
No predictors guide NCC ablation in perinodal AT; leaves open prospective studies to identify reliable markers.

P
Population
113 patients with focal atrial tachycardias (ATs) who underwent electrophysiologic study and radiofrequency catheter ablation, including 20 cases with focal ATs located in the perinodal area.
I
Intervention
Radiofrequency catheter ablation in the noncoronary aortic cusp (NCC)
C
Comparator
Radiofrequency catheter ablation from the endocardial right atrium at the perinodal region
O
Outcome
Clinical and electrophysiological characteristics to predict the true original site of perinodal ATs
Main Result
Absolute Event Rate: 25% vs 75%
Approximately 25% of perinodal atrial tachycardias require ablation in the noncoronary aortic cusp, but there are currently no reliable clinical or electrophysiological predictors to identify these cases prior to ablation.

Ju et al. (2012) conducted an observational in Perinodal atrial tachycardias (n=113). Noncoronary aortic cusp (NCC) ablation vs. Endocardial right atrium ablation was evaluated on Successful elimination of perinodal atrial tachycardia. Among patients with perinodal focal atrial tachycardias, 25% required ablation in the noncoronary aortic cusp, with no clinical or electrophysiological clues predicting the true original site.
