Key result
Radiofrequency catheter ablation of AVNRT guided by anatomical landmarks was successful in all 66 patients, with the mid-septal region being the most common successful site (72.7%).

Anatomical landmark-guided AVNRT ablation appears feasible; hypothesis-generating and requires prospective validation before practice change.

Is radiofrequency catheter ablation guided by anatomical landmarks safe and efficacious in patients with AV nodal reentrant tachycardia?
Radiofrequency catheter ablation of the atrioventricular nodal reentrant circuit guided by anatomical landmarks is safe and efficacious, with the mid-septal annulus being the most common successful site.
Song et al. (1999) conducted an observational in AV nodal reentrant tachycardia (AVNRT) (n=66). Anatomical approach for radiofrequency catheter ablation was evaluated on Successful anatomical sites for ablation and complications. Radiofrequency catheter ablation of AVNRT guided by anatomical landmarks was successful in all 66 patients, with the mid-septal region being the most common successful site (72.7%).
