Methods A linear ablation of the right atrial isthmus was performed during coronary sinus pacing (n = 13), atrial flutter (n = 6), or both rhythms (n = 4). Because of recurrent spontaneous induction of atrial fibrillation, ablation was performed during sinus rhythm (without coronary sinus pacing) in one patient. Pulmonary vein isolation (PVI) is an effective procedure for atrial fibrillation (AF). The role of additional cavotricuspid isthmus (CTI) block ablation remains controversial in AF patients without atrial flutter (AFL). Therefore, this study aimed to explore the clinical outcome of additional CTI block ablation in patients without AFL. Methods 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).

Cavotricuspid isthmus (CTI) ablation is the treatment of choice for symptomatic and recurrent typical, isthmus-dependent atrial flutter (AFL). 1, 2 Although acutely highly successful, a significant number of patients with successful CTI ablation will develop atrial fibrillation (AF) during follow-up. 3, – 5 The development of AF after successful CTI ablation is high in patients Andres Enriquez, Axel Sarrias, Roger Villuendas, Fariha Sadiq Ali, Diego Conde, Wilma M.

The aim of this study is to assess whether CTI ablation after PV isolation reduces inducibility of … The impact of isthmus ablation on AF recurrences differs according to the clinically predominant atrial arrhythmia and suggests a possible role of the RA isthmus in the occurrence of AF in some patients. Ablation of class IC atrial flutter in patients with therapy-resistant AF is a novel approach to management of this patient subset. Impact of prophylactic cavotricuspid isthmus ablation in atrial fibrillation recurrence after a first pulmonary vein isolation procedure.
