Article
2024 European Heart Rhythm Association/Heart Rhythm Society/Asia Pacific Heart Rhythm Society/Latin American Heart Rhythm Society expert consensus statement on catheter and surgical ablation of atrial fibrillation
In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007, the first joint expert cons...

Article
Outcomes of catheter ablation of atrial tachyarrhythmia guided exclusively by activation map**
Complex atrial tachyarrhythmias (CATs) are commonly observed in patients with prior catheter ablation or cardiac surgery. These arrhythmias are challenging to map and ablate. Historically, entrainment map** ...

Catheter ablation of frequent monomorphic ventricular arrhythmias in Andersen-Tawil syndrome: case report and focused literature review
Andersen-Tawil syndrome type 1 is a rare autosomal dominant disease caused by a KCNJ2 gene mutation and clinically characterized by dysmorphic features, periodic muscular paralysis, and frequent ventricular ar...

Surviving sudden cardiac arrest—successes, challenges, and opportunities
Sudden cardiac arrest (SCA) is the most common cause of death in the world. This manuscript highlights the various challenges in prevention and early management of SCA and also discusses the current state of S...

Incidence of new-onset atrial fibrillation in COVID-19 is associated with increased epicardial adipose tissue
Coronary artery calcium (CAC) and epicardial adipose tissue (EAT) can predict AF in the general population. We aimed to determine if CAC and EAT measured by computed tomographic (CT) scanning can predict new-o...

Effects of opioid receptor agonist and antagonist medications on electrocardiogram changes and presentation of cardiac arrhythmia: review article
Mortality associated with prescription opioids has significantly increased over the past few decades and is considered a global pandemic. Prescribed opioids can cause cardiac arrhythmias, leading to fatal outc...

Article
Amiodarone is associated with increased short-term mortality in elderly atrial fibrillation patients with preserved ejection fraction
Amiodarone is commonly used in atrial fibrillation (AF). Long-term use of amiodarone is associated with significant toxicities especially in elderly patients. However, in the short term after hospitalization o...

First-line ablation of ventricular tachycardia in ischemic cardiomyopathy: stratification of outcomes by left ventricular function
First-line catheter ablation of ventricular tachycardia/ventricular fibrillation (VT/VF) in patients with ischemic cardiomyopathy (ICM) has been associated with improved outcomes; however, most benefit seems t...

Long-term durability of posterior wall isolation using the cryoballoon in patients with persistent atrial fibrillation: a multicenter analysis of repeat catheter ablations
There is a growing interest in performing pulmonary vein isolation (PVI) with concomitant posterior wall isolation (PWI) using the cryoballoon for the treatment of patients with persistent atrial fibrillation ...

Left atrial posterior wall isolation in conjunction with pulmonary vein isolation using cryoballoon for treatment of persistent atrial fibrillation (PIVoTAL): study rationale and design
There is growing evidence in support of pulmonary vein isolation (PVI) with concomitant posterior wall isolation (PWI) for the treatment of patients with symptomatic persistent atrial fibrillation (persAF). Ho...

Article
Periprocedural and long-term safety and feasibility of direct oral anticoagulants in patients with biological valve undergoing radiofrequency catheter ablation for atrial fibrillation: a prospective multicenter study
Direct oral anticoagulants (DOACs) are contraindicated in patients with atrial fibrillation (AF) and mechanical cardiac valves. However, safety and efficacy are controversial in patients with biological cardia...

Article
Concealed structural heart disease discovered at cardiac magnetic resonance in patients with ventricular extrasystoles from ventricular outflow tract and apparently normal hearts
Outflow tract (OT) premature ventricular contractions (PVCs) are commonly found in clinical practice; in most cases, PVCs are benign and observed in structurally normal hearts, not requiring any therapeutic in...

Outcomes of junctional ectopic tachycardia ablation in adult population—a multicenter experience
Idiopathic junctional ectopic tachycardia (JET) is typically refractory to antiarrhythmic agents. Catheter ablation for JET is feasible but is associated with high risk of unintended atrioventricular (AV) bloc...

T-wave inversion as a manifestation of COVID-19 infection: a case series
Cardiac involvement with COVID-19 infection has become evident by elevated troponin, cardiac arrhythmias, ST segment elevation, myocarditis, fulminant heart failure, and sudden cardiac death. We aimed to descr...

Ventriculoatrial conduction in patients without high-grade AV block: when is it present?
Ventriculoatrial (VA) conduction is a critical component in many arrhythmias, has a diagnostic value in electrophysiology study (EPS), and is implicated in pacemaker-mediated arrhythmias. This study sought to ...

WATCHMAN implantation in patients with a history of atrial fibrillation and intracranial hemorrhage
Use of oral anticoagulation (OAC) in patients with a history of intracranial hemorrhage (ICH) is often considered high risk as OAC-related ICH is associated with high mortality rates. Left atrial appendage clo...

QT prolongation in a diverse, urban population of COVID-19 patients treated with hydroxychloroquine, chloroquine, or azithromycin
Hydroxychloroquine, chloroquine, and azithromycin have been used for treatment of COVID-19, but may cause QT prolongation. Minority populations are disproportionately impacted by COVID-19. This study evaluates...

Peri-procedural use of direct anticoagulation agents during cardiac device implantation: vitamin K antagonists vs direct oral anticoagulants
Warfarin is deemed safe compared to bridging with heparin in the peri-procedure setting while implanting cardiac devices. The timing of discontinuation and re-initiation of direct anticoagulant agents (DOACs) ...
