References Radiofrequency ablation is an established method for treatment of type I atrial flutter. The assessment of creation of complete bidirectional isthmus block following linear ablation of the isthmus is an integral part of ablation procedure. Atrial flutter (AFL) is one of the most common cardiac arrhythmias in humans, affecting approximately 190,000 people in the United States in 2005; its prevalence is expected to increase to 440,000 by 2050 because of the increasingly older population. 1 AFL usually coexists with atrial fibrillation (AF) and is generally initiated through a transitional phase of AF. 2 AFL most often occurs in the context of structural heart disease (e.g., valvular heart disease, ischemic heart disease Ablation of typical atrial flutter involves interruption of the right atrial macroreentrant circuit via the application of energy along the critical isthmus between the tricuspid valve and the inferior vena cava (IVC).

Atypical atrial flutter (non−isthmus dependent) circuits are amenable to catheter ablation, especially in centers with advanced mapping systems. The ablation procedure is similar to that for typ

1–3 However, patients also may experience typical atrial flutter arising from the cavotricuspid isthmus (CTI) after ablation of AF. 4 Because LA ablation may alter the normal activation pattern of the LA, 2 it is possible that the 12-lead ECG of CTI-dependent flutter may not appear “typical” after AF ablation. However, the effects of LA ablation on the Success rate is high and complication risk is low. Atrial flutter ablation can be utilized as an initial rhythm control strategy instead of antiarrhythmic drugs since this procedure is low risk Radiofrequency ablation (RFA) is the treatment of choice of cavotricuspid isthmus (CTI)-dependent atrial flutter. Procedural time is highly variable due to anatomical structures. This study aimed to characterize CTI anatomy by transesophageal 3D echocardiography imaging (3D-TEE) to identify anatomic structures related to longer ablation time.

Atrial flutter occurs when your heart's electrical signals tell the upper chambers of your heart (atria) to beat too quickly. 2021-03-16 The definition of the anatomical substrate of reentry in atrial flutter has allowed the recognition of narrow, critical areas of the circuit, where radiofrequency ablation can interrupt reentry. In common flutter the isthmus between the inferior vena cava and the tricuspid valve appears the best target, but ablation between the coronary sinus and tricuspid valve can also be effective in some cases.

To our knowledge, surgical dissection of the cavotricuspid isthmus (CTI) for treatment of typical atrial flutter (AFL) has not been reported previously. A surgical approach, however, may be needed for catheter access for AFL ablation in patients with complex congenital structures with or without surgical repair,1 or for hybrid approach for atrial fibrillation ablation.2
