2015-12-23 1 INTRODUCTION. A radiofrequency (RF) catheter‐based linear ablation along the cavo‐tricuspid isthmus (CTI) is the established therapeutic approach for CTI‐dependent atrial flutters. 1, 2 The endpoint of the CTI linear ablation is to achieve bidirectional conduction block along the CTI. 3 A CTI linear ablation generally has a high success rate, and several parameters during the ablation 2010-09-28 PDF | On Jun 1, 2020, Alireza Sepehri Shamloo and others published Catheter ablation of atrial flutter: Critical isthmus identification and localization | Find, read and cite all the research you 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.

Feb 3, 2015 #1 Background The isthmus between the inferior vena cava and the tricuspid annulus has been shown to be involved in the reentry circuit of common atrial flutter. The effects of radiofrequency catheter ablation of this isthmus were examined in the canine model of atrial flutter due to reentry around the tricuspid annulus. Radiofrequency (RF) ablation of cavo-tricuspid isthmus (CTI) is widely accepted as a first-line therapy for typical atrial flutter (AFl), with high acute and long-term success rates when bidirectional isthmus block is achieved. 5–8 The aim of this multicentric prospective observational study was to assess the feasibility, acute efficacy, and safety of AMIGO™ for CTI ablation in patients with typical AFl. The concept of a mitral isthmus was first described during the observation of intra-atrial conduction block during ablation of left lateral accessory pathways. 3 In their study, Luria et al noted that ablation in the region between the left inferior pulmonary vein and mitral annulus caused conduction block in 6.9% of their 159 ablation procedures. 3 The block was manifest as a change in the CS activation during ongoing orthodromic reciprocating tachycardia. An incremental pacing from the low right atrial isthmus produced a conduction delay and block, and initiated atrial flutter.

However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve. A summary of atrial flutter ablation is discussed including indications and complications. A comparison to atrial fibrillation ablation is made. The interatrial conduction ablation including a cavo-tricuspid isthmus ablation significantly affects the wave dynamics of atrial fibrillation (AF) and facilitates the AF termination or atrial tachycardia conversion of the AF after the circumferential pulmonary vein isolation.

DOI: 10.1161/CIRCEP.117.005191 October 2017 3 Deployment of an MIL remains technically challeng-ing and regularly requires not only extensive endocar-dial ablation but frequently epicardial ablation from within the coronary sinus (CS). Transvenous catheter ablation has become the therapy of choice for patients with recurring, isthmus-dependent right atrial flutter. Achieving bidirectional conduction block in the cavotricuspid isthmus is decisive for both acute and long-term therapy success and essentially depends on the selected ablation method and the lesion size. At 1 year after the last procedure, 87 patients with mitral isthmus ablation and 69 without (P=0.002) were arrhythmia free without antiarrhythmic drugs, mitral isthmus ablation being the only In particular, mitral isthmus ablation is difficult and may warrant entry into the coronary sinus to achieve complete block.

Eventually, the ablation catheter was withdrawn to the right side and used to map the right atrium. RA activation appeared to be counterclockwise but was not entrained from the right side.
