BACKGROUND: Variation of atrial electromechanical delay (AED) in early phase after catheter ablation in patients with atrial fibrillation is lacking. METHODS: 55 consecutive patients restored sinus rhythm after ablation were included. Echocardiography was performed at 4 hours, 1 day and 3 days after radiofrequency catheter ablation, and AED was measured simultaneously by echocardiography with pulse Doppler imaging and pulse wave tissue Doppler imaging (PW-TDI)...

BACKGROUND: Leadless cardiac pacing (LCP) has emerged as a new modality for permanent pacing. We sought to describe comparative outcomes between LCP and transvenous pacemakers. METHODS: Patients receiving LCP (Micra and Nanostim) between 2014-17 at the Mayo Clinic Heart Rhythm Enterprise practice (Rochester, MN; Jacksonville, FL and Scottsdale, AZ) were identified. We identified 1:1 age and sex matched controls receiving single chamber transvenous ventricular pacemakers (TVP)...

BACKGROUND: Atrial fibrillation (AF) promotes atrial remodeling that in turn promote AF perpetuation. The aim of our study was to investigate the impact of AF history length on one-year outcome of AF catheter ablation in a cohort of patients enrolled in the Atrial Fibrillation Ablation Registry. METHODS: We described the real-life clinical epidemiology, therapeutic strategies and the short- and mid-term outcomes of 1948 patients (71.9% with paroxysmal AF) undergoing AF ablation procedures, stratified according to AF history duration (< 2 years or ≥ 2 years)...

BACKGROUND: Cardiovascular implantable electronic device (CIED) leads are a nidus for right atrial thrombi. Right-to-left thromboembolism across a patent foramen ovale (PFO) is a putative mechanism for ischemic stroke and PFO has been associated with stroke. We used a novel unbiased case-only study design to assess the effect modification of PFO-associated ischemic stroke risk by presence of CIED. We hypothesized that presence of CIED, as a nidus for right atrial thrombus formation, magnifies the PFO-ischemic stroke relationship; therefore, among hospitalized ischemic stroke patients we would find a higher prevalence of CIED in patients with PFO...

INTRODUCTION: Several clinical studies have demonstrated that remote monitoring (RM) offers potential benefits in transvenous ICD. The potential interest of RM in S-ICD recipients has never been evaluated. The aim of this study was to evaluate the alert burden and its clinical relevance in a prospective cohort of S-ICD recipients. METHODS: We prospectively and consecutively enrolled all patients undergoing S-ICD implantation at Lille University Hospital from September 2015 to January 2017 and gave them a LATITUDE™ NXT RM system...

The HCN4 gene encodes a subunit of the hyperpolarization-activated cyclic nucleotide-gated channel, type 4 that is essential for the proper generation of pacemaker potentials in the sinoatrial node. The HCN4 gene is often present in targeted genetic testing panels for various cardiac conduction system disorders and there are several reports of HCN4 variants associated with conduction disorders. Here, we report the in vitro functional characterization of four rare variants of uncertain significance (VUS) in HCN4, identified through testing a cohort of 296 sudden unexpected natural deaths...

BACKGROUND: The aim of the present study was to determine whether postprocedural antibiotic reduces the risk of infection related to the cardiac implantable electronic device (CIED) implantations. METHODS: The present investigation is a randomized, prospective, single blinded controlled trial. All consecutive patients who presented for new CIED implantation, generator replacement, or upgrade were randomized into three groups: A) No antibiotic, B) Intravenous (IV) antibiotic for one day, C) one day IV plus 7-day oral antibiotic...

INTRODUCTION: A spontaneous type I ECG pattern and/or unheralded syncope are conventionally used as risk markers for primary prevention of sudden cardiac arrest/death (SCA/SCD) in Brugada Syndrome (BrS). In this study, we determine the prevalence of conventional and newer markers of risk in those with and without previous aborted SCA events. METHODS: All patients with BrS were identified at our institute. History of symptoms were obtained from medical or from interview...

BACKGROUND: A left ventricular (LV) endocardial lead implant to achieve cardiac resynchronization therapy (CRT) is feasible when a conventional implant failed due to anatomical or technical issues or when the venous implant was performed but the patient did not respond to therapy. METHODS: Data about the implantation procedure (age, sex, clinical characteristics, anticoagulant use, previous devices), patient characteristics (indication, technique used, lead model, complications), and follow-up (clinical and echocardiographic outcome, LV lead electrical measurements) were analyzed for all CRT systems implanted using LV endocardial lead, due to failed conventional implant or non-response, between April 2011 and November 2016...

PURPOSE: Low dose-adenosine triphosphate (LD-ATP) is useful for diagnosing ATP-sensitive atrial tachycardia. However, the clinical implications of the sensitivity of LD-ATP in atrioventricular nodal reentrant tachycardia (AVNRT) still remain unknown. This study aimed to evaluate the mechanism of LD-ATP sensitivity in slow-fast AVNRT. METHODS: We estimated the sensitivity of LD-ATP in slow-fast AVNRT by a 2-4 mg ATP intravenous injection during the tachycardia. We evaluated the atrial-His interval, tachycardia termination mode, prevalence of a lower common pathway (LCP), and successful ablation site in slow-fast AVNRT with LD-ATP sensitivity...

BACKGROUND: Transcutaneous stimulation of the auricular branch of the vagus nerve (AB-VNS) is a potentially non-invasive, inexpensive and safe approach for vagus nerve stimulation that suppresses the induction and duration of atrial fibrillation and reduces sympathetic nerve outflow in healthyhumans. Researchers have not determined whether AB-VNS affects ventricular arrhythmias. OBJECTIVE: To evaluate the antiarrhythmic effects of noninvasive AB-VNS on ventricular arrhythmias induced by myocardial infarction (MI)...

Dislocation of the epicardial pacemaker into the peritoneal cavity is an uncommon but potentially life-threatening complication.We report a case of a 74-year-old with an abdominally implanted epicardial pacemaker that migrated through the peritoneum to the excavatio rectovesicalis. The laparoscopic approach was chosen because of the increased risks of perioperative morbidity and decreased survival. The generator was implanted into a pocket beneath the anterior rectus sheath and the lead was peritonalized with a running suture...
