Delayed occurrence of complete atrioventricular block after radiofrequency ablation of atrioventricular node reentrant tachycardia. Follow-up

Atrioventricular nodal block with atrioventricular nodal reentrant tachycardia ablation.

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...

Long-Term Follow-Up After Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia in Children.

BACKGROUND Catheter ablation of the slow conducting pathway (SP) is treatment of choice for atrioventricular nodal reentrant tachycardia (AVNRT). Although there are abundant data on AVNRT ablation in adult patients, little is known about the long-term results ≥3 years after AVNRT ablation in pediatric patients. METHODS AND RESULTS Follow-up data from 241 patients aged ≤18 years who had underg...

Familial Occurrence of Atrioventricular Nodal Reentrant Tachycardia.

BACKGROUND Atrioventricular nodal reentrant tachycardia (AVNRT) is considered a sporadic disease occurring in ≈22.5 cases per 10 000 in the general population. We define the prevalence and characteristics of familial AVNRT among patients who underwent radiofrequency ablation. METHODS AND RESULTS Ablation reports of all patients with familial AVNRT (at least 2 first-degree family members) who ...

Fast pathway ablation for atrioventricular node reentrant tachycardia.

The pioneering surgical reports of Ross et al. (1) and Cox et al. (2) set the stage for catheter ablation of atrioventricular (AV) node reentrant tachycardia by demonstrating that this type of tachycardia could be cured without damage to the compact AV node or impairment of AV conduction. Several experimental and clinical studies (3-8) have indicated that the anterior and posterior inputs into ...
