Atrial flutter ablation in a patient with Marfanoid syndrome and anomalous cavotricuspid isthmus.

Radiofrequency catheter ablation of common-type atrial flutter guided by conventional versus electroanatomical mapping.

Radiofrequency catheter (RF) ablation aiming the complete conduction block of the cavotricuspid isthmus has become treatment of choice for common type atrial flutter. Different approaches to guide the ablation procedure are used. For the conventional approach multipolar catheters in the right atrium and in the coronary sinus are required to detect the induction of conduction block via the isthm...

Effects of cavotricuspid isthmus ablation on atrioventricular node electrophysiology in patients with typical atrial flutter.

BACKGROUND The atrial musculature in the cavotricuspid isthmus is a part of posterior inputs to the AV node. In patients with typical atrial flutter, effects of radiofrequency ablation of this isthmus on AV node conduction are still unknown. METHODS AND RESULTS This study included 16 patients with clinically documented typical atrial flutter. Group 1 had 8 patients without and group 2 had 8 p...

Successful Ablation of Cavotricuspid Isthmus-dependent Atrial Flutter Guided by Contact Force Vector in a Patient After a Tricuspid Valve Replacement

A 46-year-old man after a tricuspid valve replacement due to traumatic severe tricuspid regurgitation developed cavotricuspid isthmus-dependent counterclockwise atrial flutter. During a linear ablation using a contact force-sensing irrigated ablation catheter, the flutter could be terminated by a radiofrequency application within a deep pouch just below the bioprosthetic tricuspid valve.

Ablation of Post Transplant Atrial Flutter and Pseudo-fibrillation Using Magnetic Navigation via a Superior Approach

Ablation of cavotricuspid ishtmus flutter and atrial tachycardia in a complex substrate has never been reported using remote navigation via superior approach. Venous access was obtained via right internal jugular for ablation and left subclavian for duodecapolar catheter placement into the coronary sinus. In a posttransplant patient presenting with both regular and irregular tachycardia, both c...

Remote magnetic catheter navigation for cavotricuspid isthmus ablation in patients with common-type atrial flutter Vollmann: Remote magnetic isthmus ablation

Electrogram polarity and cavotricuspid isthmus block during ablation of typical atrial flutter.

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. The purpose of this study was to determine wheth...
