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 Maximum electrogram-guided ablation of cavotricuspid isthmus-dependent atrial flutter. Cheng, Tony; Liu, Ying LU; Kongstad Rasmussen, Ole LU; Hertervig, Eva LU and Yuan, Shiwen LU () In Journal of Electrocardiology 46 (6). p.670-675 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.

Se hela listan på academic.oup.com Radiofrequency (RF) catheter ablation is one of the most common strategies for the current management of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL).

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. 678910111213141516 Recent studies have shown that a resulting bidirectional conduction block in the CTI should be the end point of the ablation procedure.

However, sometimes the atrial activation sequence does not clearly establish the presence or absence of complete block. A presentation from the Poster Session 3 session at ESC Congress 2013 In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure. However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve. 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.

The atrial musculature in the cavotricuspid isthmus significantly contributed to the slow AV node conduction. 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). The procedure was repeated in 3 patients (3.75%) due to flutter recurrence.

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. [Ablation of the cavotricuspid isthmus.

Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). We aimed to study whether different CTI morphologies had different impacts on procedural success for CRYO and RF. Design. This study randomized 153 patients with CTI-dependent AFL (median age 65 years; range 34–82) to RF or Electrogram Polarity in Atrial Flutter Ablation. Introduction: The atrial activation sequence around the tricuspid annulus has been used to assess whether complete block has been achieved across the cavotricuspid isthmus during radiofrequency ablation of typical atrial flutter. However, sometimes the atrial activation sequence does not clearly establish the presence or absence of complete Background: Catheter ablation of the cavotricuspid isthmus (CTI) is traditionally performed using fluoroscopy and electroanatomical mapping systems. Zero-fluoroscopy approaches have recently been studied, mostly using the EnSite® mapping system (St. Jude Medical Inc., St. Paul, MN). Ballany W, Choudhuri I, Djelmami-Hani M, Cooley RL.
