Aims: Cardiac resynchronization therapy (CRT) device implantation has been shown to reduce morbidity and mortality in selected patients with heart failure. We sought to investigate the utilization and in-hospital complications of cardiac resynchronization therapy defibrillator (CRT-D) and pacemaker (CRT-P) implantations in the United States from 2003 to 2013. Methods and results: Patients receiving CRT-D or CRT-P were identified in the National Inpatient Sample database (NIS), using the International Classification of Diseases-Ninth Revision-Clinical Modification procedure codes...

Aims: Primary prevention implantable cardioverter defibrillators (ICDs) are established therapy for reducing mortality in patients with left ventricular systolic dysfunction and ischaemic heart disease (IHD). However, their efficacy in patients without IHD has been controversial. We undertook a meta-analysis of the totality of the evidence. Methods and results: We systematically identified all RCTs comparing ICD vs. no ICD in primary prevention. Eligible RCTs were those that recruited patients with left ventricular dysfunction, reported all-cause mortality, and presented their results stratified by the presence of IHD (or recruited only those with or without)...

Although echocardiograms are frequently performed within 24 h of sudden cardiac death, the utility of left ventricular ejection fraction (LVEF) to predict survival is unknown. In this is single center retrospective cohort study of patients admitted to the intensive care unit or coronary care unit after in-hospital or out-of-hospital sudden cardiac death, LVEF <40% was not a significant predictor of survival at 30 days or hospital discharge. ABSTRACT Background: Cardiopulmonary resuscitation and early defibrillation have been shown to improve outcomes of cardiac arrest...

We present the case of a 75-year-old patient with a single-chamber St. Jude Medical internal cardioverter defibrillator (ICD; St. Jude Medical, St. Paul, MN, USA) for primary prevention, who was admitted with 39 inappropriate ICD shocks because of atrial fibrillation with rapid ventricular frequention, despite magnet placement. Review of the device manual and literature revealed that apart from different responses to magnet placement programmed for the various manufacturers, the type of magnet and the positioning can be of specific interest...

The indications for placement of an implantable cardioverter defibrillators (ICDs) have greatly expanded over the last years. However, standard transvenous approach is not suitable for a subset of patients who cannot benefit from ICD therapy. Here, we have demonstrated the feasibility and efficacy of extrapericardial ICD placement through a minimally invasive access in intact hearts as well as in postmyocardial infarction large animal models. Based on our data, we conclude that extrapericardial ICD placement is a feasible approach that may be a valuable alternative or adjunct to current defibrillator lead systems...

INTRODUCTION: Public Access Defibrillation - the use of Automated External Defibrillators (AEDs) by lay bystanders before the arrival of Emergency Medical Services - is an important strategy in delivering prompt defibrillation to victims of out-of-hospital cardiac arrest and can greatly improve survival rates. Such public-access AEDs are used rarely: one barrier might be poor understanding and content of current signage to indicate their presence. The aim of this project was to develop a sign, with public consultation, that better indicated the function of an AED, and an associated poster to encourage its use...

BACKGROUND: Efforts to guide automated external defibrillator placement for out-of-hospital cardiac arrest (OHCA) treatment have focused on identifying broadly defined location categories without considering hours of operation. Broad location categories may be composed of many businesses with varying accessibility. Identifying specific locations for automated external defibrillator deployment incorporating operating hours and time of OHCA occurrence may improve automated external defibrillator accessibility...

BACKGROUND: There have been concerns that Electromagnetic security systems such as walk-through metal detectors (WTMDs) can potentially cause electromagnetic interference (EMI) in certain active medical devices including implantable cardiac pacemakers and implantable neurostimulators. Incidents of EMI between WTMDs and active medical devices also known as personal medical electronic devices (PMED) continue to be reported. This paper reports on emission measurements of sample WTMDs and testing of 20 PMEDs in a WTMD simulation system...

Competitive sports activity is associated with an increased risk of sudden cardiovascular death (SCD) in adolescents and young adults with clinically silent cardiovascular disorders. While in middle-aged/senior athletes atherosclerotic coronary artery disease accounts for the vast majority of SCDs, in young athletes the spectrum of substrates is wider and includes inherited (cardiomyopathies) and congenital (anomalous origin of coronary arteries) structural heart diseases. Inherited ion channel diseases have been implicated in SCDs occurring with an apparently normal heart at autopsy...

BACKGROUND: Implantable cardioverter defibrillators (ICDs) improve survival in patients with heart failure due to ischemic cardiomyopathy, but their benefit in non-ischemic cardiomyopathy (NICM) has been recently questioned. We performed a meta-analysis of randomized clinical trials to examine the effect of ICDs on total mortality and arrhythmic death in patients with NICM. We also examined the impact of age and cardiac resynchronization therapy (CRT) on the relative effect of ICD compared to control...

BACKGROUND: After defibrillation of initial ventricular fibrillation (VF), it is crucial to prevent refibrillation to ensure successful resuscitation outcomes. Inability of the late Na(+) current to inactivate leads to intracellular Ca(2+) dysregulation and arrhythmias. Our aim was to determine the effects of ranolazine and GS-967, inhibitors of the late Na(+) current, on ventricular refibrillation. METHODS AND RESULTS: Long-duration VF was induced electrically in Langendorff-perfused rabbit hearts (n=22) and terminated with a defibrillator after 6 minutes...

Short QT syndrome is a malignant cardiac disease characterized by the presence of ventricular tachyarrhythmias leading to syncope and sudden cardiac death. Currently, international guidelines establish diagnostic criteria when QTc is below 340 ms. This entity is one of the main diseases responsible for sudden cardiac death in the pediatric population. In recent years, clinical, genetic and molecular advances in pathophysiological mechanisms related to short QT syndrome have improved diagnosis, risk stratification, and preventive measures...
