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.

Cavotricuspid isthmus ablation with the ablation index Although RF ablation is a well-accepted treatment for typical AFL, with a high acute success rate of up to 97%, 5–11 it is well-known that the wide variability in the anatomy of the CTI can make the ablation extremely challenging. 2016-09-28 · The aim of this study was to provide useful information about the cavotricuspid isthmus (CTI) and surrounding areas morphology, which may help to plan CTI radio-frequency ablation.

Comparison of the efficacy of cooled-tip and 8-mm- tip catheters for radiofrequency catheter ablation of the cavotricuspid isthmus: a meta-analysis. Pacing and

We thus studied the feasibility and effectiveness of AI-guided CTI for AFL. Methods: Procedural and 6-month outcomes of ablation for AFL were retrospectively compared between consecutive patients undergoing either AI-guided ablation of CTI (n = 43; AI target of 500 for anterior 2/3 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. The aim of this study is to assess whether CTI ablation after PV isolation reduces inducibility of atrial arrhythmias, particularly AF. Abstract The cavotricuspid isthmus (CTI) had a complex architecture with an anisotropic conduction property. An incremental pacing from the low right atrial isthmus produced a conduction delay and block, and initiated atrial flutter. Radiofrequency catheter ablation of the CTI was very effective in eliminating the typical atrial flutter. Background The atrial musculature in the cavotricuspid isthmus is a part of posterior inputs to the AV node. In patients with typical atrial flutter, effects of radiofrequency ablation of this isthmus on AV node conduction are still unknown.

It is the part of the atrium in which the re-entrant electrical activity of atrial flutter circulates.

Successful ablation of cavo-tricuspid isthmus dependent atrial flutter in a patient with Senning operation/Senning operasyonlu hastada kavo-trikuspit istmus bagimli atriyal flutterin basarili ablasyonu. cavotricuspid isthmus, from the positive to the negative poles of E1 and E2. During coronary sinus pacing before ablation, the initial polarity of the electrograms recorded at E1 and E2 is predominantly positive, consistent with clockwise activation across the cavotricuspid isthmus, from the negative to the positive poles of E1 and E2. 2009-06-15 Dielectric Tissue Imaging in Cavotricuspid Isthmus Ablation (ERUCA) 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. Atrial fibrillation (AF) is a common finding in patients undergoing cavotricuspid isthmus ablation for isthmus dependent right atrial flutter (RAF). Little is known about the time of its occurrence.

An incremental pacing from the low right atrial isthmus produced a conduction delay and block, and initiated atrial flutter. Radiofrequency catheter ablation of the CTI was very effective in eliminating the typical atrial flutter. However, atrial fibrillation often occurred after ablation of the Maximum electrogram-guided ablation of cavotricuspid isthmus-dependent atrial flutter.

At the ablation procedure the patient presented in sinus rhythm. The cavotricuspid isthmus (CTI), lying between the inferior vena cava (IVC) and the tricuspid annulus, is the common target of AF ablation.

Conclusions Radiofrequency ablation of the cavotricuspid isthmus was effective in eliminating typical atrial flutter without injury of antegrade fast AV node conduction. The atrial musculature in the cavotricuspid isthmus significantly contributed to the slow AV node conduction.

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. The aim of this study is to assess whether CTI ablation after PV isolation reduces inducibility of atrial arrhythmias, particularly AF. The acute success rate for ablation of cavotricuspid isthmus–dependent atrial flutter is high even after adjusting for reporting bias. Surprisingly, the use of large-tip and irrigated catheters showed only a very strong trend toward improving acute ablation success rates over 4- to 6-mm tip catheters. Radiofrequency ablation (RFA) is the treatment of choice of cavotricuspid isthmus (CTI)-dependent atrial flutter. Procedural time is highly variable due to anatomical structures.

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. The aim of this study is to assess whether CTI ablation after PV isolation reduces inducibility of … Introduction: PVI is a well-established therapy for patients with drug refractory atrial fibrillation (AF). However, it remains unclear whether prophylactic cavotricuspid isthmus (CTI) ablation at the time of PVI improves long-term freedom from AF. Hereby, we report on a MRI-guided cavotricuspid isthmus ablation.

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.
