for Radio- Frequency Ablation of Cavotricuspid Isthmus- Dependent Atrial Flutter. Comparison of Direct Mid-Isthmus Approach Versus Linear 

A cavotricuspid isthmus (CTI) pouch, a common anatomical anomaly, complicates the creation of a CTI block line for common atrial flutter (cAFL) because ablation within the pouch is difficult. The clinical significance of the pouch for a cAFL circuit has not fully been explained.

Introduction: The atrial activation sequence around the tricuspid annulus has been used to assess whether complete block has been achieved across the cavotricuspid isthmus during radiofrequency ablation of typical atrial flutter. However, sometimes the atrial activation sequence does not clearly establish the presence or absence of complete block. A presentation from the Poster Session 3 session at ESC Congress 2013 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.

We evaluated the anatomy of the region with a multidetector 16-slice computed tomography (CT) scan and correlated this with subsequent procedural difficulty. Atrial flutter results from a microreentry circuit in the right atrium, which necessarily involves the cavotricuspid isthmus.

Conclusions Radiofrequency ablation of the cavotricuspid isthmus was effective in eliminating typical atrial flutter without injury of antegrade fast AV node conduction. The atrial musculature in the cavotricuspid isthmus significantly contributed to the slow AV node conduction.

Cryoablation (CRYO) is an alternative to radiofrequency (RF) for catheter ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). 26 Jun 2015 Atrioventricular (AV) block is a rare complication of cavotricuspid isthmus radiofrequency (RF) ablation.

Typical atrial flutter (AFL) is a common arrhythmia that is responsible for about 10% of all hospitalizations for supraventricular tachycardia in adults.1 The reentrant circuit through the cavotricuspid isthmus is located in the right atrium, and the left atrium is then activated passively.2 Cavotricuspid isthmus radiofrequency (RF) ablation is considered a first-line therapy to achieve rhythm • Recurrent supraventricular tachycardias after successful cavotricuspid isthmus ablation can mimic a typical atrial flutter (AFL). • This case report illustrated a pseudo typical AFL occurring after successful cavotricuspid isthmus ablation with a unique mechanism using the isthmus between the intercaval scar and the inferior vena cava baffle in a patient with a prior history of Senning Se hela listan på en.wikipedia.org Cavotricuspid isthmus (CTI) ablation is the treatment of choice in preventing recurrences of typical atrial flutter (AFl).

Feb 3, 2015 #1 In addition, all patients underwent ablation of the typical atrial flutter through the blocking line of the cavotricuspid isthmus, regardless of previous recording of that arrhythmia. Vesical catheterization was performed to monitor diuresis and the possible use of diuretics, because of the fluid volume injected via the irrigated ablation Background: Typical atrial flutter involving the cavotricuspid isthmus (CTI) is the most common reentrant arrhythmia in congenital heart disease and ablation is effective in its management. However, congenital heart disease patients often require surgical interventions on their tricuspid valve that utilize prosthetic material, making CTI ablation technically challenging. RESULTS: With standard catheters, complete ablation of the cavotricuspid isthmus was achieved in 18 patients (90%).

The acute success rate for ablation of cavotricuspid isthmus–dependent atrial flutter is high even after adjusting for reporting bias. Surprisingly, the use of large-tip and irrigated catheters showed only a very strong trend toward improving acute ablation success rates over 4- to 6-mm tip catheters. Radiofrequency ablation (RFA) is the treatment of choice of cavotricuspid isthmus (CTI)-dependent atrial flutter.

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.

Patients with Atrial Flutter and patients with Atrial Fibrillation scheduled to undergo RF ablation of the cavotricuspid isthmus (CTI). Both male and female subjects who meet all eligibility criteria and give written informed consent will be enrolled in the study. The cavotricuspid isthmus (CTI) in the lower pan of the right atrium, between the inferior caval vein and the tricuspid valve, is considered crucial in producing a conduction delay and.
