This is done in the cardiac electrophysiology lab by causing a ridge of scar tissue in the cavotricuspid isthmus that crosses the path of the circuit that causes atrial flutter. 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. Atrial flutter ablation may be challenging in the presence of modified/complex anatomy.

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. The acute ablation success is inferior to common atrial flutter ablation, probably due to multifactorial issues such as worse clinical baseline characteristics, multiple concomitants atypical atrial flutters, and the instability of the clinical flutter during the procedure. (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.

It is mandatory to precisely define the critical isthmus for those procedures. In this purpose, image integration gives a roadmap before starting the procedure, and remote magnetic navigation may be helpful as well in these complex anatomies. 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 authors describe the case of a 51-year-old man, with no relevant medical history, referred for a cardiology consultation in 2009 for paroxysmal atrial fibrillation. Ablation of Flutter 2 at CTI 16. LA Map During Flutter 3 17 330 msec. Ablation of Flutter 3 18. –Mitral isthmus ablation in 11/23 1 Jan 2004 Introduction. Radiofrequency (RF) ablation of typical atrial flutter (AFl) uses as target the inferior vena cava-tricuspid annulus (IVC-TA) isthmus A 46-year-old man after a tricuspid valve replacement due to traumatic severe tricuspid regurgitation developed cavotricuspid isthmus-dependent counterclockwise atrial flutter.

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. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 2015-03-16 Figure 5. During ablation on the mitral isthmus, the atrial flutter prolonged (270 msec) and then terminated. 3.

Impact of a 4q25 genetic variant in atrial flutter and on the risk of atrial fibrillation after cavotricuspid isthmus ablation. Roberts JD(1), Hsu JC, Aouizerat BE, Pullinger CR, Malloy MJ, Kane JP, Olgin JE, Marcus GM. Linear ablation of the right atrial (RA) isthmus is an effective and curative therapy for type I atrial flutter (AFL). 1 Presently, complete elimination of bidirectional isthmus conduction (BIC) is accepted as the best marker of long-term success. 1 2 AFL recurrences are associated with failure to achieve complete BIC block at conclusion of the ablation procedure. 3 Repeat electrophysiological studies in patients with an AFL recurrence show regression or complete disappearance of isthmus 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.
