Catheter ablation is considered to be a first-line treatment method for many people with typical atrial flutter due to its high rate of success (>90%) and low incidence of complications. 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.

Isthmus ablation

Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). 3 Jun 2015 Catheter ablation of cavotricuspid valve isthmus is nowadays the first-line nonpharmacological treatment for atrial flutter and the acute success Creation of a complete bidirectional conduction block across the inferior right atrial cavo-tricuspid isthmus is the accepted marker for long-term success in 27. Febr. 2018 Bei typischem rechtsatrialen und Isthmus-abhängigem Vorhofflattern beträgt die. Zykluslänge nie unterhalb von 200 ms und sehr selten oberhalb Figure 7: Testing for complete conduction block in the cavotricuspid isthmus after typical atrial flutter ablation The schematics (A and C) show blue and white Blue arrows represent the cavotricuspid isthmus, which forms the narrowest part in each of the flutter circuits shown. Linear ablation through this crucial isthmus 10 Oct 2012 carvotricuspid isthmus (CTI) which is the target for ablation treatment.

METHODS AND RESULTS: Between January 1997 and June 2002, 632 patients underwent cavotricuspid isthmus ablation for the treatment of typical atrial flutter at the Cleveland Clinic Foundation. Bidirectional cavotricuspid isthmus block was considered to indicate a successful procedure. Eighty-three ablation procedures were performed in 80 patients (82.5% men, 61 ± 10 years of age).

Das Wichtigste []. Die Isthmusablation ist eine Prozedur in der Elektrophysiologie, bei der der Isthmus im Rechten Vorhof abladiert wird. Die Isthmusablation ist sinnvoll und indiziert bei rezidivierendem typischem rechtsartrialen Vorhofflattern.

Radiofrequency catheter ablation of the CTI was very effective in eliminating the typical atrial flutter. However, atrial fibrillation often occurred after ablation of the isthmus and needs further treatment. 2019-11-01 Maurer et al; Ablation of the Superolateral Mitral Isthmus Line Circ Arrhythm Electrophysiol. 2017;10:e005191.

A cavotricuspid isthmus (CTI) block may be an easier and safer alternative to left atrial lines for this purpose. Non-inducibility after AF ablation is associated with a higher success rate.

CTI ablation is commonly performed at the same time as PVI to treat AFL or as an empiric therapy. Conduction recovery is a recognized problem after linear ablation in the left atrium (e.g., mitral isthmus ablation) and is proarrhythmic. 2021-01-01 Therefore, the importance of ablating the coronary sinus and the right atrial isthmus to prevent the recurrence of both typical and atypical AFL has been emphasized w1x.Our technique allows a simple isolation of the entire cavotricuspid region by applying two ablation lines from a pursestring suturein front of the coronary sinusto the coronary sinus and the atrio-ventricular groove, respectively. 2015-12-23 1 INTRODUCTION. A radiofrequency (RF) catheter‐based linear ablation along the cavo‐tricuspid isthmus (CTI) is the established therapeutic approach for CTI‐dependent atrial flutters. 1, 2 The endpoint of the CTI linear ablation is to achieve bidirectional conduction block along the CTI. 3 A CTI linear ablation generally has a high success rate, and several parameters during the ablation 2010-09-28 PDF | On Jun 1, 2020, Alireza Sepehri Shamloo and others published Catheter ablation of atrial flutter: Critical isthmus identification and localization | Find, read and cite all the research you Cavotricuspid isthmus (CTI) ablation is the treatment of choice in preventing recurrences of typical atrial flutter (AFl).
Ethical aspects of research

This study aimed to assess the contribution of the VOM in achieving MI conduction block. An anterior ablation line, connecting the right upper pulmonary vein with anterior mitral annulus, including the scar area, was acomplished in 73% (n=11). In 82% of these (n=9), conversion to sinus rhythm (SR) was obtained with the first RF ablation set; effective mitral isthmus block (MIB) was achieved in all except 1 (technical limitations).

In difficult cases, ICE imaging is ideally suited for evaluating the anatomy of the targeted cardiac region, verifying catheter tissue contact during RF energy delivery, monitoring potential ablation related complications and minimizing radiation exposure to both patient and the operator. 1 Right atrial isthmus ablation, guided by three-dimensional (3D) transesophageal echo, and 3D ICE imaging
