An implantable cardioverter defibrillator (ICD) storm involves very frequent arrhythmia episodes and ICD shocks, and it is associated with poor short-term and long-term prognosis. Radiofrequency catheter ablation (RFCA) can be used as an effective rescue treatment for patients with an ICD storm. To our knowledge, this is the first report of an infant with HCM presenting with an ICD storm and undergoing successful radiofrequency catheter ablation salvage treatment for the fast left posterior fascicular VT.

The investigation of death in young (<35 years), previously fit individuals, calls for a detailed autopsy with emphasis placed upon the examination of the heart. In most instances, the cause of cardiac death can be identified during autopsy. However, a large percentage of sudden deaths remain unexplained even after comprehensive medicolegal investigation, including autopsy, and are labelled as autopsy-negative sudden unexplained cardiac death (SUD). Still, when you look to the law, an autopsy, a much needed truth-finding-instrument, usually is not mandatory and is left up to the discretion of various medical or legal authorities, which when making a decision, balance various, often conflicting interests of the state and society on the one hand and of the deceased and his family on the other...

BACKGROUND: No precise tools exist to predict appropriate shocks in patients with a primary prevention ICD. We sought to identify characteristics predictive of appropriate shocks in patients with a primary prevention implantable cardioverter defibrillator (ICD). METHODS: Using patient-level data from the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II) and the Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT), we identified patients with any appropriate shock...

Among the implantable cardioverter defibrillator recipients, there is still a subgroup of patients in whom the defibrillation threshold is too high and the maximal shock output of the implantable cardioverter defibrillator can fail to terminate a ventricular arrhythmia. We report a new thoracoscopic minimally invasive approach to place a standard array electrode in the transverse pericardial sinus of a patient implanted with a cardiac resynchronization and defibrillation therapy device with persistent high defibrillation threshold...

Heart failure has a high prevalence in the general population. Morbidity and mortality of heart failure patients remain high, despite improvements in drug therapy, implantable cardioverter-defibrillators and cardiac resynchronisation therapy. New transcatheter implantable devices have been developed to improve the treatment of heart failure. There has been a rapid development of minimally invasive or transcatheter devices used in the treatment of heart failure associated with aortic and mitral valve disease and these devices are being incorporated into routine clinical practice at a fast rate...

PURPOSE: Cardiac implantable electronic devices (CIEDs) have traditionally been a contraindication for magnetic resonance imaging (MRI). Recent studies suggest that MRI can be conducted safely in select patients with pacemakers (PPMs) and implantable cardioverter defibrillators (ICDs). We sought to determine the safety of MRI in patients with CIEDs, using a protocol for patient selection and device programming. METHODS: This is a prospective, single-center study...

PURPOSE: Patients with implantable cardioverter defibrillators (ICDs) have an ongoing risk of sudden incapacitation that may cause traffic accidents. However, there are limited data on the magnitude of this risk after inappropriate ICD therapies. We studied the rate of syncope associated with inappropriate ICD therapies to provide a scientific basis for formulating driving restrictions. METHODS: Inappropriate ICD therapy event data between 1997 and 2014 from 50 Japanese institutions were analyzed retrospectively...

Risk stratification in Brugada syndrome in young patients remains challenging. We investigated the clinical characteristics, prognosis, and risk in young patients with the Brugada syndrome. We studied 95 patients with the Brugada syndrome aged ≤19 years. The median age at diagnosis was 12.9 years. The clinical presentation was sudden cardiac death in 7% and syncope in 21%. The remaining 72% were asymptomatic at diagnosis. Electrical abnormalities were present in 36%, including spontaneous type I electrocardiogram (12%), sinus node dysfunction (9%), atrioventricular block (17%), intraventricular conduction delay (16%), and atrial arrhythmias (8%)...

Importance: Improvement in left ventricular ejection fraction (EF) to >35% occurs in many patients with reduced EF at baseline. To our knowledge, whether implantable cardioverter defibrillator (ICD) therapy improves survival for these patients is unknown. Objective: To examine the efficacy of ICD therapy in reducing risk of all-cause mortality and sudden cardiac death among patients with an EF ≤35% at baseline, with or without an improvement in EF to >35% during follow-up...

BACKGROUND: The goal was to test the effectiveness of a structured pain management programme after invasive electrophysiological interventions in cardiology including ablation of atrial fibrillation (AF) or ventricular tachycardia (VT) and implantation, or explantation, of pacemakers or implantable cardioverter defibrillators. METHODS: This was a prospective study with a pre-/post-design where a post-intervention group (116 consecutive patients) was compared to a pre-intervention group (102 consecutive patients) after implementation of a structured pain-management programme using the numeric rating scale (NRS 0-10) and classified as moderate-to-severe if NRS > 3...

Infections involving internal cardiac devices can be very challenging to treat, and almost universally require complete device extraction for successful management. Of the pathogens that cause device-related endocarditis, fungi such as Candida albicans are notoriously difficult to manage because of their propensity to produce large vegetations and the need for long-term treatment with potentially toxic medications. Furthermore, individuals who develop fungal, device-associated endocarditis are typically among the most complex patients, with significant comorbidities that place them at high risk for open heart procedures such as surgical device extraction...

Ventricular arrhythmias are an important cause of cardiovascular morbidity and mortality, particularly in those with structural heart disease, inherited cardiomyopathies, and channelopathies. The goals of ventricular arrhythmia management include symptom relief, improving quality of life, reducing implantable cardioverter defibrillator shocks, preventing deterioration of left ventricular function, reducing risk of arrhythmic death, and potentially improving overall survival. Guideline-directed medical therapy and implantable cardioverter defibrillator implantation remain the mainstay of therapy to prevent sudden cardiac death in patients with ventricular arrhythmias in the setting of structural heart disease...

Long term ECG monitoring has become nowadays an indispensable technology for prevention, management and treatment of many cardiac issues. Today long term ECG monitoring is achievable through loop recorders (LR) and cardiac devices (CIED) like pacemaker (PM), implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy device-defibrillators (CRT- Ds), all of which associated with remote monitoring (RM). Targeted long term ECG monitoring Patients who have recurrent non documented episodes of palpitations, unexplained episodes of syncope, cryptogenic stroke or patients with a cardiomiopathy needing a risk stratification, may benefit from long term ECG monitoring...

OBJECTIVE: To determine the incremental value of implantable cardioverter defibrillators (ICD) in contemporary optimally treated patients with heart failure (HF) undergoing cardiac resynchronisation therapy (CRT). METHODS: Consecutive patients with HF undergoing CRT-pacemaker (CRT-P) or CRT-defibrillator (CRT-D) implantation in a single tertiary care centre between October 2008 and August 2015 were retrospectively evaluated. For patients with a primary prevention indication of the CRT-D, no benefit of the ICD was defined as absence of appropriate therapy (device analysis) or lethal ventricular tachyarrhythmias (mode of death analysis) during follow-up...

Implantable cardioverter defibrillation has taken a predominant place in secondary and primary preventions of sudden rhythmic cardiac death in high-risk patients. However, in certain clinical situations, the implantation of definitive system should be postponed. The LifeVest, a portable external cardiac defibrillator system, has emerged as a novel therapeutic option before a final decision.

REVIEW
Polychronis Dilaveris, Christos-Konstantinos Antoniou, Konstantinos A Gatzoulis
Publication of the DANISH randomized trial led to considerable debate, given that it demonstrated no survival benefit stemming from current implantable cardioverter-defibrillator (ICD) allocation criteria in patients with non-ischemic dilated cardiomyopathy (NIDCM). Consequently, a thorough reconsideration of our approach to sudden cardiac death (SCD)-risk stratification appears to be in order. NIDCM encompasses a wide spectrum of disease entities, often with differing arrhythmogenicity; however, in its kernel, is still defined by the fundamentals of electrophysiology that dictate that abnormal tissue, exhibiting altered electrophysiological properties is necessary for arrhythmogenesis, but not enough, given that formation of functional circuits is required...
