Implication

May favor initial NCC ablation for focal AT near anterior septum; leaves open need for randomized comparison to septal approach.

Key Points

To define the optimal mapping and catheter ablation strategy for focal atrial tachycardias originating around the anterior atrial septum.
Evaluated 47 consecutive patients (20.7% of 227 with atrial tachycardia; mean age, 56.3±11.6 years) presenting with anterior atrial septal focal atrial tachycardias.
Conducted activation mapping and catheter ablation targeting the right atrial septum, noncoronary aortic cusp, or the aortic mitral junction.
Initial ablation was successful at the noncoronary cusp in 84.8% of patients (28 of 33) compared to 35.7% (5 of 14) at the right atrial septum.
A total of 46 of 48 tachycardias in 45 patients were permanently eliminated, with final successful sites at the noncoronary cusp in 35 patients, the right atrial septum in 8 patients, and the aortic mitral junction in 3 patients.

Structured PICO

What is the optimal mapping and ablation strategy for focal atrial tachycardias surrounding the anterior atrial septum?

Population

47 patients with focal atrial tachycardias surrounding the anterior atrial septum (AAS-ATs) out of 227 consecutive patients with AT, mean age 56.3±11.6 years.

Intervention

Mapping and ablation targeting the noncoronary cusp (NCC), right atrial septum (RAS), and aortic mitral junction.

Outcome

Successful elimination of focal atrial tachycardias.

Most focal atrial tachycardias surrounding the anterior atrial septum can be successfully eliminated from within the noncoronary cusp, establishing it as the preferential ablation site.
