We hypothesised that performing an empiric Cavotricuspid Isthmus CTI line ablation in case of non-inducibility of arrhythmia will lead to good outcomes. Long-term outcomes of empiric versus entrained CTI ablation in CHD patients with right-sided supraventricular arrhythmias were examined.

Introduction. The anatomy of the cavotricuspid isthmus (CTI) is an important determinant of the ease of radiofrequency ablation. We evaluated the anatomy of the region with a multidetector 16-slice computed tomography (CT) scan and correlated this with subsequent procedural difficulty.

hence, favoring the perpetuation of a reentrant circuit. [Ablation of the cavotricuspid isthmus. Randomized prospective study of radiofrequency ablation with irrigated catheters versus standard catheters]. [Article in Spanish] Peña Pérez G(1), Hernández Madrid A, González Rebollo JM, Rodríguez A, Gómez Bueno M, Camino A, Moro C. This study sought to investigate specific contact force (CF) parameters to guide cavotricuspid isthmus (CTI) ablation and compare the outcome with a historical control cohort. Methods and Results Patients (30) undergoing CTI ablation were enrolled prospectively in the Study cohort and compared with a retrospective Control cohort of 30 patients.

Cavotricuspid isthmus ablation

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. We examined 140 autopsied human hearts from Caucasian individuals of both sexes (29.3% females) with a mean age of 49.1±17.2 years. We macroscopically investigated the lower part of the right atrium, the CTI, the 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).

1 Background: Typical atrial flutter involving the cavotricuspid isthmus (CTI) is the most common reentrant arrhythmia in congenital heart disease and ablation is effective in its management. 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. 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.

Long-term Results: A total of 109 cavotricuspid isthmus ablation procedures for typical atrial flutter were undertaken during this time period: 16 with the MiFi catheter and 93 Radiofrequency (RF) ablation of the cavotricuspid isthmus. (CTI) has become first line therapy for typical atrial flutter. Although various techniques have been Mar 16, 2020 In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure.

26 Jun 2015 Atrioventricular (AV) block is a rare complication of cavotricuspid isthmus radiofrequency (RF) ablation. In most cases, it is related to direct

A 74-year-old man without structural heart disease was admitted with documented episodes of paroxysmal symptomatic typical right atrial flutter. At the ablation procedure the patient presented in sinus rhythm. 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 eliminati … 2004-08-31 Abstract. The cavotricuspid isthmus (CTI) in the lower pan of the right atrium, between the inferior caval vein and the tricuspid valve, is considered crucial in producing a conduction delay and. hence, favoring the perpetuation of a reentrant circuit.

It is the part of the atrium in which the re-entrant electrical activity of … Cavotricuspid isthmus ablation among patients with persistent atrial fibrillation as a bridging therapy to maintain sinus rhythm — a pilot study Ablacja cieśni trójdzielno-żylnej wśród pacjentów z przetrwałym migotaniem przedsionków jako terapia pomostowa służąca utrzymaniu rytmu … 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. 2016; 18 (6): 868 – 72. Effects of Cavotricuspid Isthmus Ablation on Atrioventricular Node Electrophysiology in Patients With Typical Atrial Flutter Cavotricuspid isthmus ablation is a therapeutic option in CTI dependent flutters (2). 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. Atrial fibrillation (AF) is a common finding in patients undergoing cavotricuspid isthmus ablation for isthmus dependent right atrial flutter (RAF).

We report a case of common right atrial flutter that was ablated 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. 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.

However, the effectiveness The most common approach is to create an ablation line across the cavotricuspid isthmus (CTI). Traditionally, atrial flutter ablation has been performed with a 2006 (Engelska)Ingår i: Indian Pacing and Electrophysiology Journal, ISSN 0972-6292, E-ISSN 0972-6292, Vol. 6, nr 2, s. 100-110Artikel i tidskrift history of atrial flutter (AFL) had any benefit of prophylactic cavotricuspid isthmus block (CTIB) in addition to circumferential pulmonary vein ablation (CPVA). 2006 (engelsk)Inngår i: Indian Pacing and Electrophysiology Journal, ISSN 0972-6292, E-ISSN 0972-6292, Vol. 6, nr 2, s.

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. In difficult cases, use of intracardiac echo imaging can be invaluable in guiding the ablation. 2015-02-03 Jacques Clémenty & Michel Haïssaguerre, “An Approach to Catheter Ablation of Cavotricuspid Isthmus Dependent Atrial Flutter” Figure 1.
