Prophylactic cavotricuspid isthmus block during atrial - DiVA

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.

Procedural time is highly variable due to anatomical structures. This study aimed to characterize CTI anatomy by transesophageal 3D echocardiography imaging (3D-TEE) to identify anatomic structures related to longer ablation time. 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.

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. A presentation from the Poster Session 3 session at ESC Congress 2013 Radiofrequency Ablation of the Cavotricuspid Isthmus in Typical Atrial Flutter: Standard Catheter Versus Irrigated-Tip Catheter. A Randomized Prospective Study. Introduction.

Tada H(1), Oral H, Sticherling C, Chough SP, Baker RL, Wasmer K, Kim MH, Pelosi F Jr, Michaud GF, Knight BP, Strickberger SA, Morady F. Author information: (1)Department of Internal Medicine, University of Michigan, Ann Arbor 48109-0022, USA. The cavotricuspid isthmus (CTI), lying between the infe-rior vena cava (IVC) and the tricuspid annulus, is the common target of AF ablation.6–16 Recent studies have shown that a resulting bidirectional conduction block in the CTI should be the end point of the ablation procedure.8–13 The method most widely used to assess this complete CTI 2015-11-10 2016-09-28 Cavotricuspid isthmus (CTI) ablation is the treatment of choice in preventing recurrences of typical atrial flutter (AFl). However, little is known about long-term quality of life (QoL) after CTI ablation.

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. 2012-11-01 Request PDF | On Oct 1, 2005, Emoke Posan and others published Unexpected AV Block During Cavotricuspid Isthmus Ablation | Find, read and cite all the research you need on ResearchGate 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: 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.

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 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.

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. Vesical catheterization was performed to monitor diuresis and the possible use of diuretics, because of the fluid volume injected via the irrigated ablation 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. However, congenital heart disease patients often require surgical interventions on their tricuspid valve that utilize prosthetic material, making CTI ablation technically challenging. RESULTS: With standard catheters, complete ablation of the cavotricuspid isthmus was achieved in 18 patients (90%).

Radiofrequency ablation (RFA) is the treatment of choice of cavotricuspid isthmus (CTI)-dependent atrial flutter.
