Risks and benefits of an open irrigation tip catheter in intensive radiofrequency catheter ablation in patients with non-paroxysmal atrial fibrillation.

BACKGROUND Although open irrigation tip catheters (OITC) are effective in producing transmural radiofrequency (RF) lesions, they have the potential for fluid overload or excessive tissue damage. METHODS AND RESULTS The 203 patients with non-paroxysmal atrial fibrillation (NPAF; 85.2% males, 55.2+/-10.6 years old) who underwent RF catheter ablation (RFCA) were analyzed retrospectively. Clinica...

Catheter ablation of paroxysmal atrial fibrillation.

In the recent years, many investigators have proved the efficacy and safety of catheter ablation in patients with paroxysmal atrial fibrillation. Further studies would be necessary to decrease the recurrence rate and complication rate, and make the procedure more simple.

Catheter Ablation for Paroxysmal Atrial Fibrillation

It is clear that the global burden of atrial fibrillation (AF) and its associated economic footprint in terms of healthcare utilization is rising exponentially. Cumulative evidence suggests that catheter ablation is superior to antiarrhythmic drugs in the management of paroxysmal and persistent AF in terms of improved quality of life, AF-free survival, and AF burden. It is hoped that catheter a...

Radiofrequency catheter ablation for drug-refractory paroxysmal atrial fibrillation in a patient with Ebstein’s anomaly

Ebstein’s anomaly is a rare congenital heart disease in which the tricuspid valve is displaced toward the apex of the right ventricle (RV). It is commonly associated with atrial arrhythmia, especially Wolff-Parkinson-White syndrome. In fact, up to 20% of patients with Ebstein’s anomaly have 1 or more accessory pathways owing to tricuspid valve malformation, most of which are located along these...

Transvenous Radiofrequency Catheter Ablation for Atrial Flutter and Atrial Fibrillation

Transvenous radiofrequency catheter ablation (RFA) for treatment of atrioventricular (AV) reentrant tachycardia and AV nodal reentrant tachycardia is remarkably successful. To the best of my knowledge, there has not been a large randomized trial comparing RFA with other treatments for these tachycardias. The lack of such trials is due at least in part to the self-evident efficacy of RFA in this...
