Background: Ablation index (AI) has been evaluated as guidance quality marker for pulmonary vein isolation, but not for linear ablation of the cavotricuspid isthmus (CTI) for typical right atrial flutter (AFL). We thus studied the feasibility and effectiveness of AI-guided CTI for AFL. Cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) is a common atrial arrhythmia, often occurring in association with atrial fibrillation. It can cause significant symptoms because of a typically rapid ventricular rate, and may cause embolic stroke, and rarely a tachycardia-induced cardiomyopathy. It has been demonstrated that successful cavotricuspid isthmus ablation of typical atrial flutter combined with atrial fibrillation (AF) sometimes influences the preablation history of paroxysmal AF. However, the effectiveness of only isthmus ablation on AF itself is unclear. Se hela listan på 2019-11-01 · Radiofrequency (RF) catheter ablation of the cavotricuspid isthmus (CTI) in typical or common atrial flutter (AFL) is recommended for patients who are symptomatic or refractory to pharmacologic rate control. 1 The CTI is a well-defined quadrilateral-shaped anatomic area, bordered by the tricuspid valve (TV) anteriorly and the eustachian valve and eustachian ridge (ER) posteriorly. Se hela listan på Radiofrequency (RF) catheter ablation is one of the most common strategies for the current management of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL).

Little is known about the time of its occurrence. Purpose We aimed to investigate the incidence of AF early after RAF ablation in a well-defined, prospective cohort. Methods cavotricuspid isthmus The electrically conductive tissue that separates the inferior vena cava from the tricuspid valve. It is the part of the atrium in which the re-entrant electrical activity of atrial flutter circulates. Cavotricuspid isthmus ablation using a catheter equipped with mini electrodes on the 8 mm tip: a prospective comparison with an 8 mm dumbbell-shaped tip catheter and 8 mm tip cryothermal catheter. Europace.

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). The procedure was repeated in 3 patients (3.75%) due to flutter recurrence.

Apr 8, 2013 To our knowledge, surgical dissection of the cavotricuspid isthmus (CTI) for treatment of typical atrial flutter (AFL) has not been reported  Apr 1, 2006 An Approach to Catheter Ablation of Cavotricuspid Isthmus Dependent Atrial Flutter. O'Neill, Mark D and Jaïs, Pierre and Jönsson, Anders and  Creation of a complete bidirectional conduction block across the inferior right atrial cavo-tricuspid isthmus is the accepted marker for long-term success in  To verify and re-emphasise the efficacy of the max electrogram-guided approach for ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). It has been demonstrated that successful cavotricuspid isthmus ablation may be effective in preventing paroxysmal atrial fibrillation.

Ablation of the left atrium was completed, and the catheters were moved to the right atrium to ablate a line along the cavotricuspid isthmus. At this point, a pericardial effusion was observed on intracardiac echocardiography. No patient hypotension was noted. It was suspected the perforation occurred during ablation of the mitral line. Cavotricuspid isthmus-dependent atrial flutter is an arrhythmia that is frequently encountered in the electrophysiology laboratory, and can be successfully ablated with conventional mapping and ablation techniques.

METHODS AND RESULTS: An observational study without a control group in patients referred for treatment of common atrial flutter. Aims: A significant proportion of patients develop atrial fibrillation (AF) following cavotricuspid isthmus (CTI) ablation for typical atrial flutter (AFl). The objective of this study was to assess whether the presence of advanced interatrial block (aIAB) was associated with an elevated risk of AF after CTI ablation in patients with typical AFl and no prior history of AF. Hereby, we report on a MRI-guided cavotricuspid isthmus ablation. A 74-year-old man without structural heart disease was admitted with documented episodes of paroxysmal symptomatic typical right atrial flutter.

J Patient Cent Res Rev. 2016;3:243-4. Published quarterly by Midwest-based health system Advocate Aurora Health and indexed in PubMed Central, the Background: Complete bi-directional isthmus block is the endpoint of typical atrial flutter ablation. The purpose of this study was to investigate the feasibility of the local double potential (DP) interval and the change in transisthmus conduction time for predicting complete isthmus block after ablation of the cavotricuspid isthmus.
