Pulsed Field Ablation of Paroxysmal Supraventricular Tachycardia: A Prospective Multicenter Single-Arm Study in China.

Background: Pulsed field ablation (PFA) has gained attention in cardiac electrophysiology, but data on its application to paroxysmal supraventricular tachycardia are limited. This study aimed to assess the feasibility and safety of PFA and its combination with radiofrequency ablation for treating paroxysmal supraventricular tachycardia.

Methods: A prospective, multicenter, single-arm study was conducted across 8 centers in China.

Percutaneous left atrial appendage closure with SeaLA device in non-valvular atrial fibrillation.

Objectives: The clinical efficacy and safety of a novel left atrial appendage (LAA) occluder of the SeaLA closure system in patients with nonvalvular atrial fibrillation (NVAF) were reported.

Background: Patients with NVAF are at a higher risk of stroke compared to healthy individuals. Left atrial appendage closure (LAAC) has emerged as a prominent strategy for reducing the risk of thrombosis in individuals with NVAF.

CLOSE protocol versus lower ablation index value for paroxysmal atrial fibrillation: A randomized noninferior clinical trial.

Introduction: The optimized ablation index (AI) value for catheter ablation of atrial fibrillation (AF) remains to be defined. We aimed to compare the efficacy and safety of CLOSE protocol and lower AI protocol in paroxysmal AF.

Methods And Results: Patients with symptomatic, drug-resistant paroxysmal AF for first ablation were prospectively enrolled from September 2020 to January 2022.

The Safety and Feasibility of Pulsed-Field Ablation in Atrioventricular Nodal Re-Entrant Tachycardia: First-in-Human Pilot Trial.

Background: The incidence of atrioventricular conduction system damage during the catheter ablation procedure has long been a safety concern in patients with atrioventricular nodal re-entrant tachycardia (AVNRT). Pulsed-field ablation (PFA) with high tissue selectivity is a promising technique to address this problem in patients with AVNRT.

Objectives: This study aimed to evaluate the safety and feasibility of PFA in patients with AVNRT.

Investigation of the Cellular Pharmacological Mechanism and Clinical Evidence of the Multi-Herbal Antiarrhythmic Chinese Medicine Xin Su Ning.

Xin Su Ning (XSN), a China patented and certified multi-herbal medicine, has been available in China since 2005 for treating cardiac ventricular arrhythmia including arrhythmia induced by ischemic heart diseases and viral myocarditis, without adverse reactions being reported. It is vitally important to discover pharmacologically how XSN as a multicomponent medicine exerts its clinical efficacy, and whether the therapeutic effect of XSN can be verified by standard clinical trial studies. In this paper we report our discoveries in a cellular electrophysiological study and in a three-armed, randomized, double-blind, placebo-controlled, parallel-group, multicenter trial.

Simultaneous Endocardial and Epicardial Delineation of 3D Reentrant Ventricular Tachycardia.

Background: Mechanisms of scar-related ventricular tachycardia (VT) are largely based on computational and animal models that portray a 2-dimensional view.

Objectives: The authors sought to delineate the human VT circuit with a 3-dimensional perspective from recordings obtained by simultaneous endocardial and epicardial mapping.

Methods: High-resolution mapping was performed during 97 procedures in 89 patients with structural heart disease.

Is ablation to atrial fibrillation termination of persistent atrial fibrillation the end point?: A systematic review and meta-analysis.

Background: The ideal ablation strategy and end point for persistent atrial fibrillation (AF) have not been well founded. Defining periprocedural AF termination as the end point of catheter ablation is still controversial. This meta-analysis aimed to analyze the differences between periprocedural AF termination and non-termination in the long-term AF recurrence rate and postoperative complications.

Pan-Asia United States PrEvention of Sudden Cardiac Death Catheter Ablation Trial (PAUSE-SCD): rationale and study design.

Background: The role of catheter ablation as an adjunct and alternative to ICD implantation is not known in patients at risk for recurrent ventricular tachycardia (VT) and sudden cardiac death (SCD) across Asia. Patients with nonischemic etiologies of cardiomyopathy, which are highly prevalent in Asia, have not been previously enrolled in randomized trials of VT ablation.

Objective: To evaluate whether preemptive catheter ablation in patients with monomorphic VT and an indication for ICD implantation results in improved clinical outcomes compared to ICD implantation with standard medical therapy alone.

Safety and efficacy analysis of one-stop intervention for treating nonvalvular atrial fibrillation.

Background: Nonvalvular atrial fibrillation (AF) is a common arrhythmia. The treatment strategy for AF mainly includes controlling symptoms and decreasing the rate of complications. Our study aimed to evaluate the safety and efficacy of combination treatment of catheter ablation and left atrial appendage (LAA) closure (one-stop intervention) in patients with nonvalvular AF.

Telehealth interventions versus center-based cardiac rehabilitation of coronary artery disease: A systematic review and meta-analysis.

Background: Cardiac rehabilitation (CR) is an evidence-based recommendation for patients with coronary artery disease (CAD). However, CR is dramatically underutilized. Telehealth interventions have the potential to overcome barriers and may be an innovative model of delivering CR.

Combined analysis of genome-wide-linked susceptibility loci to Kawasaki disease in Han Chinese.

Kawasaki disease (KD) is a dominant cause of acquired heart disease in children due to frequent complicating coronary artery lesions (CALs). Genome-wide association study and linkage analysis have recently identified 6 susceptibility loci at genome-wide significance of P < 5.0 × 10(-8) in subjects of Japanese, Taiwanese and European.
