Atrial flutter (AF) mapping has shown circular activation in the right atrium (RA), wilh a "counterclockwise" rotation in a frontal view. The myocardial isthmus between the inferior vena cava and the tricuspid valve (IVC‐T) closes the activation circuit in its caudal end. The reproducibility ...
In this chapter we will review the present status of RF ablation for common AFL, and some atypical forms, also based in right atrial circuits. 展开 关键词: radiofrequency ablation flutter mechanisms atrial reentry flutter ablation atrial mapping ...
Direct treatment of atrial flutter and atrial fibrillation--that is, attempting to prevent arrhythmia recurrences by ablating atrial tissue--has been a challenge because of uncertainty about the location of optimal target tissues as well as the amount of atrial tissue requiring destruction to effect ...
MIAMI, FL — Case volume and age may both be significant predictors of complications fromcatheter ablationofatrial flutter(AFL), suggests a new retrospective analysis of nearly 90,000 patient procedures conducted in the US[1]. Using data from the Nationwide Inpatient Sample (NIS) on catheter abl...
Cryothermal ablation treat- ment of atrial flutter--Experience with a new 9 French 8 mm tip catheter. J Interv Card Electrophysiol 2005; 12:45-54.Montenero AS, Bruno N, Zumbo F, Antonelli A, Fiocca L, Barbieri L, De Bernardi F, et al. Cryothermal ablation treatment of atrial flutter-...
Pulse Field Ablation (PFA) has been acknowledged as an effective and safe tool for ablation of Atrial Fibrillation (AF). It is known that during AF ablation, the arrhythmia may organize into atrial flutter. The left atrial posterior wall is identified as a critical source of non-Pulmonary ...
OBJECTIVES: Complete bidirectional cavo-tricuspid isthmus (CTI) block is mandatory for radio-frequency (RF) ablation of typical atrial flutter (AF). CTI block can be assessed by a simplified method using two catheters and the technique of differential pacing, but long-term results in large series...
Vein damage during the procedure happens to one in 500 patients. A small surgery is required to repair the vein when this occurs. Another surgical risk during ablation for atrial flutter is the possibility of blood filling the sac around the heart. This occurs in approximately one out of 200...
The anatomical structure of atrial flutter is now well recognized, and treatment with radiofrequency catheter ablation (RFA) is established. Several recording and ablation techniques can be applied.An increasing number of patients have been treated with RFA at the Arrhythmia Centre at Haukeland Universi...
In some patients with atrial fibrillation, atrial flutter develops after administration of class IC antiarrhythmic drugs, the so-called class IC atrial flutter. Radiofrequency ablation of the right atrial isthmus results in clinical improvement in 85% of patients and provides an alternative management ...
