Atrioventricular block during radiofrequency catheter ablation of atrial flutter: incidence, mechanism, and clinical implications.

AIMS To evaluate the incidence, mechanism, and clinical implications of atrioventricular (AV) block during catheter radiofrequency (RF) ablation of the cavotricuspid isthmus (CTI). Although RF ablation of atrial flutter is the most frequently performed ablation procedure, data on the incidence and significance of an AV block occurring during the procedure are scarce. METHODS AND RESULTS Conse...

Slow pathway modification for atrioventricular node re-entrant tachycardia: fast junctional tachycardia predicts adverse prognosis.

OBJECTIVE To examine the cycle length of the junctional tachycardia often seen during successful slow pathway ablation for atrioventricular (AV) node re-entrant tachycardia, to determine whether shorter cycle lengths predict imminent atrioventricular block. DESIGN Retrospective analysis of consecutive patients undergoing slow pathway modification. Intracardiac recordings were analysed after d...

Chronic incomplete atrioventricular block induced by radiofrequency catheter ablation.

To determine if catheter ablation of the atrioventricular (AV) junction with radiofrequency energy can induce chronic incomplete (first- and second-degree) AV block to avoid the need for a permanent pacemaker, 20 closed-chest dogs were studied. Group 1 (10 dogs) received radiofrequency energy (750 kHz) with a fixed power setting (5 or 10 W) while increasing the pulse duration from 10 to 50 seco...

مقایسه قطع کردن کامل در مقایسه با ناقص مسیر کوتاه در بیماران مبتلا به تاکی کاردی بازگشت گره ی دهلیزی-بطنی از نظر عود علایم و عوارض

Background and purpose: Catheter radiofrequency ablation is the first step in therapeutic approach to Atrioventricular nodal reentrant tachycardia (AVNRT). Different protocols for slow pathway ablation are found to have various ranges of efficacy and side effects. This study compared the effects of partial and complete ablation of the slow pathway on recurrence, symptom relief and complications...

Catheter-induced mechanical trauma to fast and slow pathways during radiofrequency ablation of atrioventricular nodal reentry tachycardia: incidence, predictors, and clinical implications.

BACKGROUND Data on the incidence and significance of catheter-induced trauma to fast and slow pathways are scarce. OBJECTIVES To evaluate the incidence, predictors, and clinical implications of inadvertent catheter-induced mechanical trauma to fast and slow pathways during radiofrequency ablation (RFA) of atrioventricular nodal reentry tachycardia (AVNRT). METHODS A total of 901 consecutive...
