WebWhat happens during atrial flutter? (12-15)Lower loop reentry atrial flutter uses a circuit that includes the CTI, as common atrial flutter, but it shortens the circuit through a gap in the crista terminalis.

WebJun 4, 2024 · Atrial flutter (AFL), a common atrial tachyarrhythmia, includes both typical and atypical forms. Radiofrequency catheter ablation (CA) has been implemented to terminate AFL with promising results [ 1 ]. However, sinus node dysfunction (SND) may coexist in patients with AFL. WebOct 4, 2016 · In the Triple A trial, patients with isolated atrial flutter were randomized to antiarrhythmic drugs, CTI ablation, or PVI. 9 Atrial flutter recurrence was 8.7% in the CTI group and 15% in the PVI group. After a second PVI, the rate of atrial flutter dropped to 5% without performing CTI.

WebJul 16, 2024 · The most common approach is to create an ablation line across the cavotricuspid isthmus (CTI). Traditionally, atrial flutter ablation has been performed with a conventional approach using two catheters, an ablation catheter and a duodecapolar catheter that is placed at the level of the tricuspid annulus to confirm the CTI block.
WebConclusion: In our study, a functional, rather than anatomic, isthmus formed by preexisting double-potential barrier at the CTI was identified in 47% of patients with isthmus-dependent AFL.
