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. Purpose We aimed to investigate the incidence of AF early after RAF ablation in a well-defined, prospective cohort. Methods

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. 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.

2021-04-22 · Objectives: This randomised trial evaluated if patients with atrial fibrillation (AF) and no history of atrial flutter (AFL) had any benefit of prophylactic cavotricuspid isthmus block (CTIB) in addition to circumferential pulmonary vein ablation (CPVA). Methods: 149 patients with AF (54% paroxysmal) were randomised to CPVA and CTIB (group CTIB+, n = 73) or CPVA alone (group CTIB−, n = 76 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.

Patients with Atrial Flutter and patients with Atrial Fibrillation scheduled to undergo RF ablation of the cavotricuspid isthmus (CTI). Both male and female subjects who meet all eligibility criteria and give written informed consent will be enrolled in the study.

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. Purpose We aimed to investigate the incidence of AF early after RAF ablation in a well-defined, prospective cohort. Methods cavotricuspid isthmus The electrically conductive tissue that separates the inferior vena cava from the tricuspid valve.

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.
