BACKGROUND: In US clinical practice, many patients who undergo placement of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death receive dual-chamber devices. The superiority of dual-chamber over single-chamber devices in reducing the risk of inappropriate ICD shocks in clinical practice has not been established. The objective of this study was to compare risk of adverse outcomes, including inappropriate shocks, between single- and dual-chamber ICDs for primary prevention...

BACKGROUND: Carbapenem resistant Acinetobacter baumannii complex (CRABC) is an emerging pathogen that causes bloodstream infections and nosocomial pneumonia. This study aimed to describe the severe infection associated with CRABC bacteremic pneumonia and to investigate risk factors for 28-day mortality. METHODS: All patients ≥18 years of age with a CRABC bacteremic pneumonia were enrolled retrospectively at five teaching hospitals in South Korea. Empirical antimicrobial therapy was defined as appropriate if administration of at least one antimicrobial agent, to which the causative pathogen was susceptible, more than 48 hours, within 5 days of the onset of bacteremia...

Anemia was shown to be associated with increased risk for adverse events in patients with heart failure (HF). However, there are limited data on the association between anemia and the risk for ventricular arrhythmias (VAs) in patients with an implantable cardioverter defibrillator (ICD). The present study population comprised 2,352 patients who were enrolled and prospectively followed up in the Israeli ICD Registry. The risk for a first appropriate ICD shock for VA was assessed by the presence of anemia, categorized at the lower tertile of hemoglobin distribution (≤12 g/dL [n = 753])...

BACKGROUND: Indication to implantable cardioverter defibrillator (ICD) for primary prevention of sudden death relies on left ventricular ejection fraction (LVEF). We measured the proportion of patients in whom indication to ICD persisted at the time of generator replacement (GR) and searched for predictors of appropriate therapies after GR. METHODS: We identified all consecutive patients who had received an ICD at our hospital, for LVEF ≤35% and no previous arrhythmias or unexplained syncope...

In the past years, cardiovascular mortality has decreased but despite these cardiovascular diseases are responsible for millions of deaths every year in the world and approximately 25% of which are sudden cardiac death (SCD). Implantable defibrillators (ICD) is proven therapy used in primary and secondary SCD prevention. Currently majority of devices use transvenous leads inserted predominantly into the right heart for both pacing and defibrillation. On the other hand, ICD may cause complica-tions, including inappropriate shocks, device-related infection and lead failure...

BACKGROUND: Up to 40% of patients with transvenous implantable cardioverter-defibrillator (ICD) experience lead-associated complications and may suffer from high complication rates when lead extraction is indicated. Subcutaneous ICD may represent a feasible alternative; however, the efficacy of the subcutaneous ICD in the detection and treatment of ventricular arrhythmias in patients with hereditary arrhythmia syndromes has not been fully evaluated. METHODS AND RESULTS: Patients with primary hereditary arrhythmia syndromes who fulfilled indication for defibrillator placement were eligible for enrollment...

BACKGROUND: Implantable cardioverter defibrillators (ICD) are capable of effectively terminating malignant ventricular arrhythmia and are the most effective way to prevent sudden cardiac death. However, some evidences demonstrated that both anti-tachycardia pacing (ATP) and ICD shock can also bring adverse prognosis. CASE PRESENTATION: A 66-year-old Han Chinese man with prior ICD implantation was admitted to our hospital because of frequent ICD shocks. Although intravenous amiodarone and esmolol succinate were administered daily, the patient suffered 155 episodes of VT/VF during 8 weeks after implantation...

Sudden unexpected death in epilepsy is a recurring calamity, yet there is little evidence to guide standards of care for supporting the bereaved. Grief in bereavement includes loss, feelings of guilt, anger and blame. There is also the shock and trauma of the sudden event. How can this be alleviated? This paper focuses on guiding the physician to support the bereaved, while recognising the limited evidence and the varying circumstances that may not always facilitate this. We propose a pathway of care and mode of communication with the deceased's family, with whom contact is currently limited...

A 75-year-old man underwent implantation of a single chamber implantable cardioverter defibrillator (ICD) for primary prevention of his underlying severe non-ischaemic cardiomyopathy. Thirteen months later, he presented to the emergency room(ER) with inappropriate ICD shocks as a result of over sensing of the right ventricular lead and double counting of the right atrial signals. The chest X-ray (CXR) revealed a right ventricular ICD lead displaced into the right atrium with coiling in the pocket. The right ventricular shocking coil was noted at the tricuspid annulus...
