João Mesquita a,⁎, António 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 Abstract The cavotricuspid isthmus (CTI) had a complex architecture with an anisotropic conduction property.

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%). With a mean of 19 15 applications.

However, certain aspects of the regional anatomy can pose technical challenges such that bidirectional block across the CTI can be difficult to achieve.1 Using a case example, we review common challenges with CTI ablation, discuss the important 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.

Introduction: PVI is a well-established therapy for patients with drug refractory atrial fibrillation (AF). However, it remains unclear whether prophylactic cavotricuspid isthmus (CTI) ablation at the time of PVI improves long-term freedom from AF.
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.
Introduction. The anatomy of the cavotricuspid isthmus (CTI) is an important determinant of the ease of radiofrequency ablation. We evaluated the anatomy of the region with a multidetector 16-slice computed tomography (CT) scan and correlated this with subsequent procedural difficulty.
Little is known about the time of its occurrence. Purpose We aimed to investigate the incidence of AF early after RAF ablation in a well-defined, prospective cohort. Methods cavotricuspid isthmus The electrically conductive tissue that separates the inferior vena cava from the tricuspid valve. It is the part of the atrium in which the re-entrant electrical activity of atrial flutter circulates.

8910111213. Abstract. 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. hence, favoring the perpetuation of a reentrant circuit. Non-uniform wall thickness, muscle fiber orientation and the marked variability in muscular architecture in the CTI should be taken into consideration from the perspective of anisotropic conduction, thus producing an electrophysiologic isthmus.
