Mitral isthmus ablation is an established strategy in the treatment of peri-mitral atrial flutter and as an adjunct to pulmonary vein isolation. The objective of this review is to summarize the techniques and specific strategies that allow for increased success and durability of mitral isthmus ablation.

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.

In rare cases of obstruction of iliofemoral veins, ablation of CTI can be performed only through the superior approach.

Isthmus ablation was performed in 16 patients (41%) in whom catheter mapping during AF showed an organized activation pattern around the tricuspid annulus.

An incremental pacing from the low right atrial isthmus produced a conduction delay and block, and initiated atrial flutter. Radiofrequency catheter ablation of the CTI was very effective in eliminating the typical atrial flutter. However, atrial fibrillation often occurred after ablation of the isthmus and needs further treatment.

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. From 01/2003 to 05/2005, 94 patients who consecutively underwent typical AFl ablation were included in the study.

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.

Ablation of cavotricuspid isthmus (CTI) is the gold standard method in the treatment of isthmus dependent atrial flutter (AFl). Venous access was obtained usually via right or left femoral veins. In rare cases of obstruction of iliofemoral veins, ablation of CTI can be performed only through the superior approach. We present a 74-year-old woman of typical AFl and dilated cardiomyopathy that Treten häufig flattern-Episoden auf, kann eine Ablations-Behandlung Abhilfe schaffen.
