The purpose of the study was to look for the influence of age on indications, clinical data and long-term results of atrial flutter (AFL) radiofrequency ablation. Methods 1154 patients, 882 males, 272 females, mean age 64卤12 years were referred for ablation of recurrent or poorly-tolerated...
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...
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...
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...
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...
Endocardial mapping has led to a detailed knowledge of reentry mechanisms in atrial flutter. Multipolar and deflecting tip catheters allow recording local electrograms from multiple areas of the right atrium, and from the coronary sinus. In common flutter, with the typical "sawtooth" pattern, ther...
Radiofrequency (RF) catheter ablation was applied in 5 consecutive patients (Pts) with atrial flutter (AFL) and structural heart diease.Target sites were localized using both anatomic approach (the isthmus between the tricuspid vale and inferior vena cava orifice,coronary sinus os) and right atrial...
The goal of radiofrequency ablation for typical atrial flutter is to interrupt conduction across the inferior vena cavatricuspid valve isthmus. The procedure is highly effective and safe, although recurrences of the arrhythmia are not rare. Incisional macroreentrant tachycardias after surgical correction...
