Atrial flutter; cavotricuspid isthmus; ablation A patient with symptomatic typical atrial flutter (AFL) underwent right atrial isthmus ablation with an 8-mm catheter. Eight months later, his typical AFL recurred. This randomized study compares two energy sources for the catheter based ablation of typical isthmus-dependent atrial flutter: The (standard) radiofrequency The Ablation of the typical atrial flutter can be considered substantially 6 mm on the cavo-tricuspid isthmus (CTI) The investigators want to prove how the html.

2021-03-30 · The positive significance of isthmus ablation in patients with atrial flutter on quality of life has recently been described. 25 In addition, catheter ablation is curative in many patients, may obviate the need for life-long antiarrhythmic drug medication, and may be more cost effective in the long term than antiarrhythmic drug therapy.

(19,20) Figure 1. Background and objective: Anterior mitral lines (AML) have been suggested as an alternative to mitral isthmus ablation for perimitral flutter (PMF) treatment. 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.

Darrat, Nicolas Lellouche, Sun Moon Kim, Muhammad Butt, Katrina Bidwell, William Lippert, Gbolahan Ogunbayo, David Hamon, Luigi Di Biase, Andrea Natale, Kevin Parrott, Claude S Elayi, Use of adenosine to shorten the post ablation waiting period for cavotricuspid isthmus‐dependent atrial flutter, Journal of Cardiovascular Electrophysiology, 10.1111/jce.13233, 28, 8 Despite many studies on new tools and strategies for cavotricuspid isthmus (CTI) ablation, there is an unmet need to improve the CTI ablation procedure.

The critical portion of the reentrant circuit is the rim of tissue between the tricuspid valve (TV) annulus and the inferior vena cava (IVC) ( Fig.1 ). 2021-02-04 Video clip of 3D mapping guided atrial flutter bi-atrial activation and ablation followed by demonstration of bidirectional lesion line block 2019-11-23 It is important to identify residual slow conduction and minimize the chance of resumption of conduction after right atrial isthmus ablation to reduce the chance of recurrence of atrial flutter (AFL). The aim of this article is to discuss the best possible way of confirming a bi-directional isthmus conduction (BIC) block after ablation of an isthmus-dependent AFL. Gen2 Isthmus-Dependent Atrial Flutter Ablation Study The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.

symptomatic patients with common atrial flutter (AF). Some authors even propose that RF ablation could be used as a first line treatment in this clinical setting.7 The cavotricuspid isthmus (CTI), lying between the infe-rior vena cava (IVC) and the tricuspid annulus, is the common target of AF ablation.6–16 Recent studies have shown

Isthmus dependent right atrial flutter is the leading AT mechanism in patients with a history of ASD repair. The mechanism of atrial flutter did not differ in relation to the mode of ASD closure (direct suture versus patch closure). ECG characteristics of the tachycardia may be misleading as they ar …

Se hela listan på onlinelibrary.wiley.com 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.

In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure. However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve.

Complete bidirectional isthmus block was achieved in 39 (89%) of 44 patients. Before ablation, the initial polarity of E1 and E2 was predominantly negative during atrial flutter and predominantly positive during coronary sinus pacing.
