Prophylactic pulmonary vein isolation during cavotricuspid isthmus ablation for atrial flutter: a meta-analysis. Pacing Clin Electrophysiol. 2019; 42:493–498. PMID: 30779174. [Google Scholar] Cavotricuspid isthmus (CTI) is the critical part of the circuit of typical atrial flutter (AFL), and catheter ablation for the bidirectional block has been an easy and safe treatment option. 1), 2), 3) Atrial fibrillation (AF) and AFL commonly occur in combination. 2002-08-01 In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure.

(B) A 12-lead ECG recorded during reverse typical AFL, with atypical F wave pattern in the inferior leads. (Reproduced with permission from Feld GK, Srivatsa U, Hoppe B. Ablation of isthmus dependent atrial flutters. 2017-10-16 DESIGN: 127 patients underwent elective cavotricuspid isthmus ablation with the indication of symptomatic, typical atrial flutter. The occurrence of atrial flutter, atrial fibrillation, cerebrovascular events and the need for additional ablation procedures for symptomatic atrial fibrillation was assessed during long-term follow-up. Background: Treatment of left atrium (LA) flutter is a relevant electrophysiological challenge due to its high complexity in mapping interpretation and, often, in effective ablation.

The aim of this study was to test the efficacy of AML (i.e.: the modified anterior line (MAL, figure, panel A), the anteroseptal line (ASL, panel B), and lines between scar tissue and anterior mitral annulus) in that scenario.

However, clinical experience has demonstrated that providers often have difficulty distinguishing AFL from atrial fibrillation. Methods We developed a novel ECG-based three-step algorithm to identify CTI-AFL based on 2017-10-16 · Isthmus is a distinct structure in the right atrium (RA) through which atrial flutter passes and makes a good target for ablation therapy. Ablation is the primary therapy in atrial flutter, particularly in CTI dependent group, with regard to its safety profile and high success rate of approximately 90%.

Kottkamp H, Hügl B, Krauss B, et al. Electromagnetic versus fluoroscopic mapping of the inferior isthmus for ablation of typical atrial flutter: A prospective randomized study. Electrograms recorded from two distal electrode pairs (E1 and E2) positioned just anterior to the ablation line were analyzed during atrial flutter and during coronary sinus pacing, before and after ablation. Complete isthmus block was verified by the presence of widely split double electrograms along the entire ablation line.

Atrial Fibrillation Ablation. Atrial Flutter In patients without a history of heart disease, cardiac surgery or catheter ablation, typical flutter ECG remains predictive of a right atrial re-entry circuit dependent on the inferior vena cava–tricuspid isthmus that can be very effectively treated by ablation, although late incidence of atrial fibrillation remains a problem. Rhythm or presentation: Atypical flutter Rhythm post procedure: Sinus Additional arrhythmias identified: None Lesion sets performed: 1. Bilateral pulmonary vein isolation 2. Mitral isthmus line 3. Mitral annular line 4.

However, congenital heart disease patients often require surgical interventions on their tricuspid valve that utilize prosthetic material, making CTI ablation technically challenging. Perimitral flutter is usually easy to diagnose but can be difficult to ablate. Ripple mapping is highly effective at locating the critical isthmus maintaining the tachycardia and avoiding anatomic ablation lines. This approach has a higher termination rate with less radiofrequency ablation required. Radiofrequency ablation is an established method for treatment of type I atrial flutter. The assessment of creation of complete bidirectional isthmus block following linear ablation of the isthmus is an integral part of ablation procedure. Ablation success is lower than in typical flutter and the recurrence rate is higher, especially in circuits located in the paraseptal areas.
