Catheter Ablation of Atypical Atrioventricular Nodal Reentrant Tachycardia.

BACKGROUND Because of its low prevalence, data on atypical atrioventricular nodal reentrant tachycardia (AVNRT) are scarce, and the optimal ablation method has not been established. Our study aimed at assessing the efficacy and safety of conventional slow pathway ablation, as applied for typical cases, in atypical AVNRT. METHODS We studied 2079 patients with AVNRT subjected to slow pathway ab...

Radiofrequency catheter ablation of atypical atrioventricular nodal reentrant tachycardia.

INTRODUCTION Published reports of radiofrequency ablation of atypical atrioventricular nodal reentrant tachycardia (AVNRT) have been limited. We present our experience in 10 consecutive patients with atypical AVNRT who underwent radiofrequency ablation of the "slow" AV nodal pathway. METHODS AND RESULTS There were 9 females and 1 male; their mean age was 44 +/- 19 years (+/- SD). The mean AVN...

Left Septal Slow Pathway Ablation for Atrioventricular Nodal Reentrant Tachycardia.

BACKGROUND Immunohistochemistry studies suggest that the anatomic substrate of the slow pathway in atrioventricular nodal reentrant tachycardia (AVNRT) is the left inferior nodal extension. We hypothesized that slow pathway ablation from the left septum is an effective alternative to right-sided ablation. METHODS AND RESULTS We analyzed our databases of AVNRT in search of cases that had used ...
