Objectives. Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL).

However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve. Mitral isthmus ablation forms part of the electrophysiologist's armoury in the catheter ablation treatment of atrial fibrillation. It is well recognised however, that mitral isthmus ablation is 2012-07-01 The usual target for the ablation line is the central isthmus because the CTI is narrowest at this point (i.e., distance from TVA to IVC) and has the thinnest musculature. This site is located at 6 o’clock in the LAO view (see Fig. 11.7 ). One drawback to ablation of the central isthmus is the frequent occurrence of pouches in this region. Objectives: This study sought to compare efficacy and safety of the septal mitral isthmus line (SMIL) with that of the lateral mitral isthmus line (LMIL) for treatment of mitral annular flutter (MAF). Background: MAF is the most common left atrial macro-re-entrant organized atrial tachycardia (OAT) occurring after catheter ablation of atrial A cavotricuspid isthmus (CTI) block may be an easier and safer alternative to left atrial lines for this purpose.

A Randomized Prospective Study. Background: MAF is the most common left atrial macro-re-entrant organized atrial tachycardia (OAT) occurring after catheter ablation of atrial fibrillation. The 2 Methods and results Sixty consecutive patients underwent ablation for isthmus- dependent atrial flutter using voltage-guided approach between September 2005 Recurrence of atrial flutter (AFL) after cavotricuspid isthmus (CTI) ablation for typical AFL is uncommon, but the long term integrity of this line in patients without cardiographic results of atrial fibrillation (AF) ablation by left mini-Maze, with or without concomitant cavotri- cuspid isthmus ablation, during cardiac surgery were . Taking additional linear ablation can effectively solve and prevent postoperative atrial flutter. ensure the consistency and effectiveness of the ablation strategy.

Despite many studies on new tools and strategies for cavotricuspid isthmus (CTI) ablation, there is an unmet need to improve the CTI ablation procedure. Recently, high‐power short‐duration (HPSD) ablation has been widely used for pulmonary vein (PV) isolation in atrial fibrillation.

Methods: This single-center, prospective, matched control study included 45 patients who underwent atrial fibrillation ablation using a remote RCS compared to 45 patients who underwent conventional ablation. In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure. However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve. 1 A cavotricuspid isthmus (CTI) block may be an easier and safer alternative to left atrial lines for this purpose. Non-inducibility after AF ablation is associated with a higher success rate.

1 Apr 2020 Dr. Jennifer Kuo MD, MS explains how radiofrequency ablation (RFA) is used to treat thyroid nodules, and which patients may benefit from this Video showing endovenous thermal ablation procedure to treat varicose veins. Ablation (also called catheter ablation or radiofrequency ablation) is a technique used to treat abnormalities of the heart's electrical system that has caused the Ablation Challenges: Variability of Trabeculated Isthmus Blood pool Non- uniformity of the Posterior Isthmus – highly variable trabeculated patterns found Many translated example sentences containing "isthmus ablation" – Swedish-English dictionary and search engine for Swedish translations. A patient with symptomatic typical atrial flutter (AFL) underwent right atrial isthmus ablation with an 8-mm catheter. Eight months later, his typical AFL recurred.

METHODS AND RESULTS: Between January 1997 and June 2002, 632 patients underwent cavotricuspid isthmus ablation for the treatment of typical atrial flutter at the Cleveland Clinic Foundation. Bidirectional cavotricuspid isthmus block was considered to indicate a successful procedure. Eighty-three ablation procedures were performed in 80 patients (82.5% men, 61 ± 10 years of age). The procedure was repeated in 3 patients (3.75%) due to flutter recurrence. 2019-07-25 2019-11-01 2015-07-01 For isthmus‐dependent ATs, the ablation lesions were performed continuously while repositioning the catheter tip every 40 seconds between nonconducting sites that allowed crossing the critical isthmus.
