Aims: The latest 2015 ESC Guidelines on the prevention of sudden cardiac death make a Class IIa recommendation for ICD implantation in patients listed for heart transplantation. This recommendation was based on expert consensus in view of the sparsity of data. Methods and results: All patients listed for heart transplantation at the University Hospitals of Leuven from 2002 until 2014 were studied retrospectively. Exclusion criteria were age <16 years, cardiac disease other than ischaemic or dilated cardiomyopathy and re-transplantation...

Aims: Implantable cardioverter defibrillators (ICDs) are an effective primary prevention of sudden cardiac death. We examined whether dual-chamber (DC) ICDs confer a greater benefit than single-chamber (SC) ICDs, and compared the long-term outcomes of recipients of each type of device implanted for primary prevention. Methods and results: Between 2002 and 2012, the DAI-PP registry consecutively enrolled 1258 SC- and 1280 DC-ICD recipients at 12 French medical centres...

Aims: The therapeutical management of atrial fibrillation (AF) in the setting of Brugada syndrome (BS) might be challenging as many antiarrhythmic drugs (AADs) with sodium channel blocking properties might lead to to the development of ventricular arrhythmias. This study sought to evaluate the clinical outcome in a consecutive series of patients with BS having undergone pulmonary vein (PV) isolation by means of radiofrequency (RF) or cryoballoon (CB) ablation and the efficacy of catheter ablation for preventing inappropriate interventions delivered by implantable cardioverter defibrillators (ICD) on a 3-year follow up...

Aims: Single-chamber (VR-ICD) and subcutaneous (S-ICD) implantable cardioverter-defibrillators are effective to protect patients against sudden death but expose them to higher risk of inappropriate shock (IS). We sought to quantify the annual rate and influencing factors of ISs in VR- and S-ICDs from the literature. Methods and results: PubMed, Embase, and Cochrane Library were searched for full text articles with IS rates. Poisson distribution estimated proportion of patients with ISs; rates were annualized based on follow-up duration...

Aims: Dual-coil implantable cardioverter defibrillator (ICD) leads have traditionally been used over single-coil leads due to concerns regarding high defibrillation thresholds (DFT) and consequent poor shock efficacy. However, accumulating evidence suggests that this position may be unfounded and that dual-coil leads may also be associated with higher complication rates during lead extraction. This meta-analysis collates data comparing dual- and single-coil ICD leads. Methods and results: Electronic databases were systematically searched for randomized controlled trials (RCT) and non-randomized studies comparing single-coil and dual-coil leads...

Inferior vena cava filter (IVCF) placement appears to be expanding over time despite absence of clear directing evidence.Two populations were studied. The first population included patients who received an IVCF between January 2005 and August 2013 at our community hospital center. Demographic information, indications for placement, and retrieval rate was recorded among other variables. The second population comprised of patients receiving an IVCF from 2005 to 2012 according to the Nationwide Inpatient Sample (NIS) using ICD-9CM coding...

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...

AIMS: In implantable cardioverter-defibrillator (ICD) patients, predictors of ICD shocks and mortality are needed to improve patient selection. Electrocardiographic (ECG) markers are simple to obtain and have been demonstrated to predict mortality. We aimed to assess the association of T-wave loop area and circularity with ICD shocks. METHODS: The study investigated patients with ICDs implanted between 1998 and 2010 for whom digital 12-lead ECGs (Schiller CS200 ECG-Network) of sufficient quality were obtained within 1 month prior to the implantation...

BACKGROUND: Peripartum cardiomyopathy (PPCM) is associated with significant morbidity and mortality. Arrhythmogenic causes of death have been implicated in a significant number of patients. However, there is a dearth of systematic studies evaluating the burden of arrhythmias in PPCM. METHODS: We used the Healthcare Utilization Project, Nationwide Inpatient Sample database (2007-2012) and identified 9841 hospitalizations for women aged ≥18years with a primary diagnosis of PPCM...

BACKGROUND: Frequent hospital attendances in patients with implantable cardioverter-defibrillators (ICDs) result in significant morbidity and health care costs. Current drugs to reduce ICD shocks and hospital visits have limited efficacy and considerable toxicity. We evaluated the efficacy and safety of azimilide, a novel oral class III antiarrhythmic, for use in ICD patients. METHODS: A total of 240 patients were enrolled in a prospective, randomized, double-blind, placebo-controlled trial to evaluate the effect of oral azimilide 75 mg daily in ICD patients with previously documented ventricular tachycardia or ventricular fibrillation, and a left ventricular ejection fraction ≤40%...

BACKGROUND: Implantable cardioverter defibrillator (ICD) is the most important management for prevention of sudden cardiac death (SCD) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). However, some patients may receive multiple ICD therapies in a short period, a condition referred as "electrical storm". OBJECTIVES: This study aimed to determine the prevalence, therapeutic options, and prognostic implications of ES in ARVC patients with an ICD...

Implantable cardioverter defibrillators (ICDs) have been shown to reduce mortality in high-risk patients. Despite several advances in programming ICDs, inappropriate shocks persist and continue to be psychologically and physically disturbing. External electromagnetic interference from electrocautery, welding, acupunctures, low-output transcutaneous electric nerve stimulators, and electronic muscle stimulators may result in inappropriate ICD sensing and shock. We present a 63-year-old female who presented to the emergency department after an ICD shock while undergoing electronic muscle stimulation in chiropractic treatment, during which light electrical pulses were sent through skin electrodes...

INTRODUCTION: Triggers and ICD interventions of ventricular arrhythmias in patients with hypertrophic cardiomyopathy (HCM) offers insight into mechanisms and treatment. METHODS AND RESULTS: Intracardiac ICD electrograms from 71 HCM patients in the HCM I and II studies were analyzed by 3 individuals. Rhythms were defined as VF (polymorphic ventricular arrhythmia), VT (monomorphic ventricular tachycardia), and ventricular flutter (VFL) (VT ≥ 240 bpm). Physical activity and rhythm preceding the arrhythmia were ascertained...

The role of catheter ablation in patients with ventricular tachycardia (VT) has evolved over the last two decades into an established treatment option. In patients with idiopathic VT catheter ablation is the gold standard treatment option with high effectiveness and low risk of complications. Due to the high risk of side effects the use of antiarrhythmic drugs is only indicated in exceptional cases. In patients with structural heart diseases, such as ischemic and dilated cardiomyopathy, VT is the most frequent cause of death...

PURPOSE: Endurance training improves oxidative stress and vascular endothelial dysfunction in patients with chronic heart failure (CHF). However, patients with CHF and an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) often avoid endurance training for fear of ICD shock. Recent studies have reported that stretching exercises enhance antioxidant activity and improve vascular responses. Therefore, we aimed to assess the effects of 4 weeks of stretching exercises on oxidative stress and vascular endothelial function in patients with CHF with an ICD or CRT-D...

PURPOSE: ICDs can improve survival in at-risk patients but no consensus exists with respect to their impact on health-related quality of life (QOL). Moreover, the data are unclear on QOL benefits in specific patient subgroups. We sought to analyze, in the INTRINSIC RV ICD trial population, health-related QOL longitudinally following ICD implant and consider impact of age, gender, and ICD shocks on QOL by employing a global measure of health-related QOL. METHODS: One thousand five hundred thirty patients had an ICD implanted...

Treatment with an implantable cardioverter-defibrillator (ICD) represents a prognostic but not symptomatic therapy. It should therefore be restricted to patients where an improvement of prognosis is possible and reasonable. ICD implantation should only be performed in patients with a life expectancy of at least 1 year at reasonable quality of life. The decision in which patient improvement of prognosis is no longer a desirable target is problematic, both medically and ethically. It is not entirely clear in which elderly patient an ICD therapy can convey prognostic benefit despite comorbidity and competitive life-threatening diseases, as it is unclear how old age should be defined...
