Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation for atrial fibrillation (AF), especially in paroxysmal 1 AF patients. In addition to a radiofrequency ablation catheter, a cryoballoon has been proven as an effective technology in PVI for AF. Recently several randomized trials have shown that cryoballoon ablation was noninferior to radiofrequency ablation with respect to ef...

This article summarizes delayed interruption in anomalous conduction through accessory connections following radiofrequency ablation attempts in three patients. The time course of the delayed interruption in accessory connection conduction suggests that such an effect is unlikely to occur after the first week following unsuccessful radiofrequency ablation.

Importance. First and foremost is the clinical problem for hich this newly advanced technique has been designed: rug-resistant hypertension. The magnitude of this problem ay be overinterpreted. There are over 60 million potential atients with hypertension in the United States and far ore when one considers that 100% of very old individuals i.e., 80 years of age) also have hypertension. Therefor...

BACKGROUND Catheter ablation of accessory atrioventricular (AV) connections using radiofrequency current has been demonstrated to be effective in the majority of patients with the Wolff-Parkinson-White syndrome or paroxysmal supraventricular tachycardia involving a concealed accessory AV connection. However, electrogram criteria have not been established to guide attempts at radiofrequency cath...

In the past decade, catheter ablation of atrial fibrillation (AF) has evolved as one of the most frequently performed procedures in tertiary arrhythmia centers worldwide. With the observation of the actively firing trigger originating from within the pulmonary veins (PVs), ablation strategies have focused at least in paroxysmal AF patients on complete isolation of the PVs. Several different abl...

BACKGROUND The long-term efficacy of radiofrequency ablation of renal autonomic nerves has been proven in nonrandomized studies. However, long-term safety of the renal artery (RA) is of concern. The aim of our study was to determine if cooling during radiofrequency ablation preserved the RA while allowing equivalent nerve damage. METHODS AND RESULTS A total of 9 swine (18 RAs) were included, ...

BACKGROUND The purpose of this study was to evaluate electrode temperatures obtained using a radiofrequency ablation system that incorporates closed loop feedback control to achieve preset target electrode temperatures and to determine if closed loop temperature control results in a lower incidence of developing a coagulum. METHODS AND RESULTS Two hundred seventy patients underwent catheter a...

Abstract Radiofrequency ablation of the sacral lateral branches targets innervation posterior sacroiliac ligaments and portion joint. These structures are also collectively referred to as joint complex. This review will discuss current diagnostic block paradigms selection criteria for branch radiofrequency ablation, varying techniques technologies utilized updates on clinical outcome literature...
