Efficacy comparison between cryoablation and radiofrequency ablation for patients with cavotricuspid valve isthmus dependent atrial flutter: a meta-analysis
We perform this meta-analysis to compare the efficacy and safety of cryoablation versus radiofrequency ablation for patients with cavotricuspid valve isthmus dependent atrial flutter. By searching EMBASE, MEDLINE, PubMed and Cochrane electronic databases from March 1986 to September 2014, 7 randomized clinical trials were included. Acute (risk ratio[RR]: 0.93; P = 0.14) and long-term (RR: 0.94;...
متن کاملSuccessful 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.
متن کاملEffects 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...
متن کاملRadiofrequency 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...
متن کاملElectrogram 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...
