Key result
Radiofrequency ablation of the slow pathway in a patient with AVNRT produced a sharply demarcated 5x5x4 mm atrial lesion distinct from the compact AV node, confirming their anatomical separation.

Supports distinct slow pathway anatomy in AVNRT; leaves open generalizability to ablation safety across patients.
Case Report (n=1)
Histological examination of an explanted heart 1 week post-ablation supports the hypothesis that the slow pathway comprises atrial approaches to the AV node and is distinct from the compact AV node.
Gamache et al. (1994) conducted a case report in Atrioventricular Nodal Reentrant Tachycardia (n=1). Catheter guided radiofrequency current ablation of the slow pathway was evaluated on Histological changes in the explanted heart. Radiofrequency ablation of the slow pathway in a patient with AVNRT produced a sharply demarcated 5x5x4 mm atrial lesion distinct from the compact AV node, confirming their anatomical separation.
