To verify and re-emphasise the efficacy of the max electrogram-guided approach for ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL).

Peri-mitral atrial flutter. ABBRE 16 Jul 2020 Catheter ablation is the first-line therapy for most patients with typical atrial flutter. The most common approach is to create an ablation line across the CTI, from the tricuspid annulus to the inferior vena cava. Tradit 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 ma 7 Apr 2014 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 0 16 Mar 2020 In patients with cavotricuspid isthmus (CTI)-dependent atrial flutter, ablation along the CTI is often a routine and straightforward procedure.

Electrogram 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 Atrial flutter ablation is a procedure to create scar tissue within an upper chamber of the heart in order to block the electrical signals that cause a fluttering heartbeat. Atrial flutter occurs when your heart's electrical signals tell the upper chambers of your heart (atria) to beat too quickly.

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 cavotricuspid isthmus ablation.

Ablation can be performed during AFL or proximal CS pacing (in sinus rhythm). The latter allows identification of a change in activation sequence on the tricuspid annular catheter, signifying slowing of CTI conduction or block ( Figure 74-3, A ). Catheter ablation is considered to be a first-line treatment method for many people with typical atrial flutter due to its high rate of success (>90%) and low incidence of complications. This is done in the cardiac electrophysiology lab by causing a ridge of scar tissue in the cavotricuspid isthmus that crosses the path of the circuit that causes atrial flutter. 2021-03-30 · The positive significance of isthmus ablation in patients with atrial flutter on quality of life has recently been described. 25 In addition, catheter ablation is curative in many patients, may obviate the need for life-long antiarrhythmic drug medication, and may be more cost effective in the long term than antiarrhythmic drug therapy. Atrial flutter ablation may be challenging in the presence of modified/complex anatomy.

In patients without a history of heart disease, cardiac surgery or catheter ablation, typical flutter ECG remains predictive of a right atrial re-entry circuit dependent on the inferior vena cava–tricuspid isthmus that can be very effectively treated by ablation, although late incidence of atrial fibrillation remains a problem.

SPAP prior to ablation was 99 ± 35 mmHg. Baseline 6-minute walk distance was 295 ± 118 m. ECG demonstrated a typical AFL pattern in only 42% of cases. Baseline AFL cycle length was longer in PAH patients compared to controls (295 ± 53 ms vs 252 ± 35 ms, P = 0.006). Cavotricuspid isthmus dependence was verified in 86% of cases.

The mechanism of atrial flutter did not differ in relation to the mode of ASD closure (direct suture versus patch closure). ECG characteristics of the tachycardia may be misleading as they ar … The lateral isthmus is generally longer and is not usually the primary ablation target. Ablation can be performed during AFL or proximal CS pacing (in sinus rhythm). The latter allows identification of a change in activation sequence on the tricuspid annular catheter, signifying slowing of CTI conduction or block ( Figure 74-3, A ).
