Clinical impact of rapid ventricular pacing on the left atrial posterior wall isolation by a cryoballoon application: a ...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Rapid ventricular pacing (RVP) was reported to improve the cooling effects of the cryoballoon (CB). The aim of this study was to investigate the safety and efficacy of RVP for left atrial posterior wall isolation (PWI) by the CB. One hundred consecutive patients (males 80, mean age 63 ± 10 years) with persistent atrial fibrillation underwent left a...

Use of a radiofrequency guidewire to simplify workflow for left atrium access: a case series.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Transseptal puncture (TSP) is widely used in catheter-based cardiac procedures to gain left atrial access, but its workflow has remained largely unchanged in the last 50 years. This study evaluated the safety and efficacy of a novel, simplified technique for TSP with a radiofrequency (RF)-powered guidewire that eliminates multiple exchanges require...

Effects of rivaroxaban on activated clotting time in catheter ablation for atrial fibrillation in Chinese patients.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

It has been observed that patients on rivaroxaban require more heparin and frequent activated clotting time (ACT) monitoring throughout the catheter ablation of atrial fibrillation, but the strategy of heparin injection varies in different studies. We sought to examine the determinants of heparin dosage in Chinese patients on rivaroxaban. We review...

Impedance drop predicts acute electrical reconnection of the pulmonary vein-left atrium after pulmonary vein isolation u...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

To determine the efficacy and identify the relevant factors for durable lesion creation in pulmonary vein isolation (PVI) using a high-power short-duration (HPSD) strategy. Thirty-two consecutive patients who underwent PVI using HPSD (50 W) (HP group: HP-G) were compared with 32 controls using normal power (25-40 W) (conventional group: C-G). The s...

Acute and long-term outcomes of left-sided atrioventricular node ablation in patients with atrial fibrillation.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

To present our experience regarding acute and long-term outcomes of left-sided atrioventricular node (AVN) ablation in patients with atrial fibrillation (AF). A total of 47 patients with AF in whom left-sided AVN ablation via retroaortic approach as a first-line approach were enrolled in this retrospective study. Indications for AVN ablation were h...

Clinical classification and the subclinical atrial fibrillation challenge: a position paper of the European Cardiac Arrh...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Symptomatic atrial fibrillation (AF) or clinical AF is associated with impaired quality of life, higher risk of stroke, heart failure, and increased mortality. Current clinical classification of AF is based on the duration of AF episodes and the recurrence over time. Appropriate management strategy should follow guidelines of Scientific Societies. ...

Signal- or temperature-based approach for cryoballoon ablation of atrial fibrillation: still an unsolved issue.

Image-guided ablation of scar-related ventricular tachycardia: towards a shorter and more predictable procedure.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

The aim of this study was to analyze the feasibility and reproducibility of using image integration software at a remote setting over the MUSIC network to perform image-guided VT ablation. Furthermore, we analyzed the efficacy of a focused workflow with electroanatomical mapping (EAM) limited to imaging-defined scar. In a prospective two-centre stu...

Reduction of radiation and contrast agent exposure in a cryoballoon ablation procedure with integration of electromagnet...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Pulmonary vein isolation (PVI) with cryoballoon ablation (CBA) is routinely guided by fluoroscopy and utilizes contrast injection to ensure catheter positioning and pulmonary vein occlusion. Non-fluoroscopic imaging techniques including electromagnetic mapping (EM) and intracardiac echocardiography (ICE) have demonstrated reduced fluoroscopy times ...

Costs and long-term outcomes following pulmonary vein isolation for atrial fibrillation in elderly patients using second...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Limited comparative data are available regarding catheter ablation (CA) of atrial fibrillation (AF) using second-generation cryoballoon (CB-2) vs. radiofrequency (RF) ablation in elderly patients (> 75 years old). The present study aimed to compare the costs and clinical outcomes in elderly patients using these two strategies. Elderly patients with...
