Effects of Renal Denervation via Renal Artery Adventitial Cryoablation on Atrial Fibrillation and Cardiac Neural Remodeling.

Cardiol Res Pract 2018 11;2018:2603025. Epub 2018 Dec 11.

Department of Cardiothoracic Surgery, Xinhua Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200092, China.

Introduction: Catheter-based renal denervation (RDN) could reduce cardiac sympathetic nerve activity (SNA) and inhibit atrial fibrillation (AF). However, the reliability is uncertain, because the renal sympathetic nerves are mainly distributed in the adventitial surface of the renal artery.

Objective: The aims of this study were to test the hypothesis that renal artery adventitial ablation (RAAA) definitely had the effects of RDN and to study the effects of RDN via renal artery adventitial cryoablation (RAAC) on AF and cardiac neural remodeling. Read More

Development of a Shock-Wave Catheter Ablation System for Ventricular Tachyarrhythmias: Validation Study in Pigs In Vivo.

J Am Heart Assoc 2019 Jan;8(2):e011038

1 Department of Cardiovascular Medicine Tohoku University Graduate School of Medicine Sendai Japan.

Background Although radiofrequency catheter ablation is the current state-of-the-art treatment for ventricular tachyarrhythmias, it has limited success for several reasons, including insufficient lesion depth, prolonged inflammation with subsequent recurrence, and thromboembolisms due to myoendocardial thermal injury. Because shock waves can be applied to deep lesions without heat, we have been developing a shock-wave catheter ablation ( SWCA ) system to overcome these fundamental limitations of radiofrequency catheter ablation. In this study, we evaluated the efficacy and safety of our SWCA system for clinical application to treat ventricular tachyarrhythmia. Read More

Front Physiol 2018 14;9:1757. Epub 2018 Dec 14.

School of Biomedical Engineering and Imaging Sciences, King's College London, London, United Kingdom.

Atrial fibrillation (AF) is a widespread cardiac arrhythmia that commonly affects the left atrium (LA), causing it to quiver instead of contracting effectively. This behavior is triggered by abnormal electrical impulses at a specific site in the atrial wall. Catheter ablation (CA) treatment consists of isolating this driver site by burning the surrounding tissue to restore sinus rhythm (SR). Read More

When is it appropriate to stop non-vitamin K antagonist oral anticoagulants before catheter ablation of atrial fibrillation? A multicentre prospective randomized study.

Eur Heart J 2018 Dec 27. Epub 2018 Dec 27.

Yonsei University Health System, 50-1 Yonsei-ro, Seodaemun-gu, Seoul 03722, Republic of Korea.

Aims: Although a recent expert consensus statement has recommended periprocedural uninterrupted (UI) non-vitamin K antagonist oral anticoagulants (NOACs) during catheter ablation of atrial fibrillation (AF) as a Class I indication, there have been no clear randomized trials. We investigated the safety and efficacy of UI, procedure day single-dose skipped (SDS), and 24-hour skipped (24S) NOACs in patients undergoing AF ablation.

Methods And Results: In this prospective, open-label, randomized multicentre trial, 326 patients (75% male, 58 ± 11 years old) scheduled for AF catheter ablation were randomly assigned in a 1:1:1 ratio to UI, SDS, and 24S at three tertiary hospitals. Read More
