Tidskriftsreferens: Sandeep Gautam. Fluorös radiofrekvens Ablation av typisk Cavotricuspid Isthmus-beroende Atrial Flutter är en säker och praktisk procedur .

Radiofrequency catheter ablation has currently become the most effective treatment for symptomatic drug-refractory atrial fibrillation (AF). 1 2 Pulmonary veins (PVs) are the main trigger source that induce AF. 3 In addition, interpulmonary isthmus zone, which is in the carina region, as well as superior vena cava, coronary sinus musculature, Marshall vein, left atrium (LA) posterior wall and left atrial appendage are capable of inducing AF. 4

However, the effects of LA ablation on the Ablation of Atrial Fibrillation at the Time of Cavotricuspid Isthmus Ablation in Patients With Atrial Flutter Without Documented Atrial Fibrillation Derives a Better Long-Term Benefit Article Jan 2011 Catheter ablation of atrial fibrillation has evolved from ablation of arrhythmogenic foci within the pulmonary veins (PV) to complete electrical isolation of the PV, often guided by perimetric mapping with a multi-polar loop catheter positioned at the rim of each of the PV ostia. 1– 4 Adding an ablation line connecting the inferior margin of the ostium of the left inferior PV (LIPV) to the mitral annulus appears to increase the success rate of treating atrial fibrillation by catheter Effect of right atrial isthmus ablation on the occurrence of atrial fibrillation: observations in four patient groups having type I atrial flutter with or without associated atrial fibrillation (Abstr). J Am Coll Cardiol A typical left atrial (LA) flutter may occur as a proarrhythmic complication of LA ablation of atrial fibrillation (AF). 1–3 However, patients also may experience typical atrial flutter arising from the cavotricuspid isthmus (CTI) after ablation of AF. 4 Because LA ablation may alter the normal activation pattern of the LA, 2 it is possible that the 12-lead ECG of CTI-dependent flutter may not appear “typical” after AF ablation. However, the effects of LA ablation on the To evaluate supplementary cavotricuspid isthmus (CTI) ablation as an adjunct to atrial fibrillation (AF) ablation in selected patients. It is unclear whether routine CTI ablation is beneficial in Patients with Atrial Flutter and patients with Atrial Fibrillation scheduled to undergo RF ablation of the cavotricuspid isthmus (CTI).

pulmonary vein isolation Atrial fibrillation (AF) is the most common arrhythmia in clinical practice and frequently coexists with cavotricuspid isthmus (CTI)-dependent (“typical”) atrial flutter (AFL) (1). Many, if not most, patients with typical flutter have concomitant AF as a trigger for AFL or will go on to develop AF (2, 3, 4, 5).

Impact of prophylactic cavotricuspid isthmus ablation in atrial fibrillation recurrence after a first pulmonary vein isolation procedure. Prophylactic CTI ablation at the time of a first PVI does not seem to improve long-term freedom from AF. Prophylactic CTI ablation at the time of a first PVI does not seem to improve long-term freedom from AF. Left-atrial size was a predictor of atrial fibrillation recurrence post-atrial flutter ablation. CONCLUSION: At long-term follow-up, approximately 82% of patients post-cavotricuspid isthmus ablation for atrial flutter developed drug refractory atrial fibrillation.

It has been demonstrated that successful cavotricuspid isthmus ablation may be effective in preventing paroxysmal atrial fibrillation. However, the effectiveness

Thus, the incidence of AT is highest in persistent AF patients undergoing stepwise ablation using the strategic combination of pulmonary vein isolation, electrogram based ablation and left atrial linear ablation.

Isthmus is a distinct structure in the right atrium (RA) through which atrial flutter passes and makes a good target for ablation therapy. Ablation is the primary 

Although there is a well-established association between atrial flutter (AFL) and AF [,, ], it remains unclear if this procedure improves the outcomes of AF patients without previously documented or induced AFL undergoing PVI [ 8 ]. Se hela listan på academic.oup.com 2004-08-15 · This study evaluates the long-term clinical outcome of 56 consecutive patients affected by atrial fibrillation and drug-related typical atrial flutter who underwent cavo-tricuspid isthmus radiofrequency ablation. Symptomatic arrhythmic events recurred after ablation in 64% of the patients during follow-up of 19 +/- 9 months. Pulmonary vein isolation (PVI) is the mainstay of catheter ablation (CA) for paroxysmal atrial fibrillation (AF). However, for persistent and long‐standing persistent AF, there are no established strategies to improve the success rate of CA. Atrial fibrillation (AF) and cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) are two separate entities that coexist in a significant percentage of patients.
