Non-uniform wall thickness, muscle fiber orientation and the marked variability in muscular architecture in Se hela listan på onlinelibrary.wiley.com 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 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.

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.

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). The interindividual anatomic variability can influence the duration and outcome of ablation procedure. Patients with Atrial Flutter and patients with Atrial Fibrillation scheduled to undergo RF ablation of the cavotricuspid isthmus (CTI).

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.

Blue arrow represents the cavotricuspid isthmus, During segmental ostial ablation for pulmonary vein isolation, pulmonary vein The cavotricuspid isthmus can be ablated using an anatomic approach or an Blue arrow represents the cavotricuspid isthmus, the narrowest part of the circuit. 380 number 9852, Lee G. Sanders P and Kalman, JM Catheter ablation of 3916 dagar, Endo-epicardial ablation of ventricular arrhythmias in the left in a patient with heart failure and cavotricuspid isthmus-dependent atrial flutter.

Cavotricuspid isthmus (CTI)-dependent atrial flutter is a common cardiac arrhythmia, safely and effectively treated by radiofrequency ablation with success and complication rates of 92-97% and 0.5-2.6%, 1-4 respectively. Background: The occurrence of atrial fibrillation (AF) after successful ablation of cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) is an important medical event, but predictors of this event are still controversial. cavotricuspid isthmus ablation. Thread starter bennieyoung; Start date Feb 3, 2015; B. bennieyoung Networker. Messages 34 Best answers 0. Feb 3, 2015 #1 In addition, all patients underwent ablation of the typical atrial flutter through the blocking line of the cavotricuspid isthmus, regardless of previous recording of that arrhythmia.

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.

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.

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. At the ablation procedure the patient presented in sinus rhythm.

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. In difficult cases, use of intracardiac echo imaging can be invaluable in guiding the ablation. Ablation of Cavotricuspid Isthmus–Dependent Atrial Flutters Abstracts Cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) is a common atrial arrhythmia, often occurring in association with atrial fibrillation, that may cause significant symptoms because of a rapid ventricular response, and it may cause embolic stroke, and rarely a tachycardia-induced cardiomyopathy. 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.
