although incidentatrial tachycardiaoratrial flutterrelated to both previously existing and newly created substrate also may be seen. The mechanisms for such arrhythmias may include focal tachycardias not identified at prior ablation, microreentrantatrial flutters, and macroreentry engaging larger areas of...
Recurrent atrial flutter and atrial fibrillation after catheter ablation of the cavotricuspid isthmus: a very long-term follow-up of 333 patients. Introduction: Radiofrequency catheter ablation of the cavotricuspid isthmus is an effective therapy for typical atrial flutter (AFL), however, the long-...
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...
Endocardial catheter ablation has been recently been proposed for the treatment of arrhythmias originating in the right atrium. In this study, we used this technique in 5 patients with paroxysmal common atrial flutter and 3 patients with paroxysmal uncommon atrial flutter. Various antiarrhythmic agents...
Atrial flutter often results from a macroreentrant circuit that uses anatomic structures within the right atrium as its borders. RF ablation at the site of an obligatory isthmus can eliminate the atrial flutter circuit. The aim of this study was to compare two approaches to atrial flutter ablation...
Image integration for atrial fibrillation ablation—pearls and pitfalls Objectives The ablation of common type atrial flutter is mainly performed by two approved techniques, whose efficacy and outcome in terms of quality of lif... PM Kistler,RJ Schilling,K Rajappan,... - 《Heart Rhythm the Officia...
OBJECTIVES: To evaluate the time to onset and the predictors of atrial fibrillation (AF) during long term follow up of patients with typical atrial flutter (AFL) treated with transisthmic ablation. DESIGN: Prospective multicentre study. METHODS AND RESULTS: 383 patients (75.4% men, mean (SD) ...
Recent studies of human type 1 atrial flutter demonstrated reentry in the right atrium and an area of slow conduction in the low posteroseptal right atrium. Direct-current catheter ablation of this area has been only moderately successful in preventing recurrence. Therefore, we performed endocardial...
latter than in the former. Simultaneous occurrence of atrial fibrillation and atrial flutter in different parts of the atria has been confirmed in patients undergoing ablation of atrial flutter and has been attributed to a possible functional interatrial block as the mechanism.79 ...
