catheter ablationECG monitoringoral anticoagulationtypical atrial flutterBackground: A considerable amount of patients with typical atrial flutter develop atrial fibrillation after cavotricuspid isthmus (CTI) ablation. No uniform recommendations are available to guide anticoagulation regimes or electrocardiogram (...
21 The tachycardia circuit may be in the right or left atrium and usually occurs around a prior incisional scar, postablation lesion, congenital heart disease lesion, or idiopathic fibrosis. This kind of flutter is also known as non-CTI dependent AFL.21 Electrocardiographic Characteristics ...
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...
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...

No post-procedure complications were observed. After 15 ± 5 months of follow-up, 16 patients (9%) had recurrence of atrial flutter. Five of the patients had been in the resistant group. In patients with atrial flutter resistant to conventional ablation therapy, the long tip (8-mm) ...
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...

Cavotricuspid isthmus (CTI) linear ablation has been established as the treatment for typical atrial flutter. Recently, ablation index (AI) has emerged as a novel marker for estimating ablation lesions. We investigated the relationship between CTI depth
and often has a ventricular rate in the range of 120 to 180 beats per minute.13The baseline on the ECG strip often is undulating and occasionally has coarse irregular activity (Figure 3). This activity may resemble atrial flutter, but it is not as uniform wave to wave as atrial flutter....
