Key result
Radiofrequency ablation of the slow pathway produced a 0.5 cm right atrial lesion without gross or histologic damage to the compact AV node.
Why the study?
Does slow pathway ablation for AV nodal reentrant tachycardia cause damage to the compact AV node?

Does slow pathway ablation for AV nodal reentrant tachycardia cause damage to the compact AV node?
Slow pathway ablation for AVNRT does not produce gross or histologic damage to the compact AV node, suggesting the reentrant circuit involves perinodal atrial tissues.
No takes yet. Share an insight, caveat, or question.
Single-case finding supports avoiding compact AV node injury; leaves open AVNRT circuit anatomy.
Olgin et al. (1996) conducted a case report in AV nodal reentrant tachycardia (n=1). Radiofrequency slow pathway ablation was evaluated on Anatomical location and extent of AV nodal damage. Radiofrequency ablation of the slow pathway produced a 0.5 cm right atrial lesion without gross or histologic damage to the compact AV node.
