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...

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: Acute myocardial infarction is a major cause of out-of-hospital cardiac arrest (OHCA). Coronary angiography (CAG) enables diagnostic confirmation of coronary artery disease and subsequent revascularization, which might improve the prognosis of OHCA survivors. Non-randomized data has shown a favorable impact of CAG on prognosis for this population. However, the optimal timing of CAG has been debated. METHODS: The clinical outcomes of 607 OHCA patients registered in CAPTURES (Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance), a nationwide multicenter registry performed in 27 hospitals, were analyzed...

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...

BACKGROUND: The impact of bystander interventions on post-arrest hospital course is sparsely studied. We examined the association between bystander interventions and length of hospital stay and admission to intensive care unit (ICU) in one-day survivors after OHCA. METHODS: This cohort study linked data of 4,641 one-day OHCA survivors from 2001-2014 to data on hospital length of stay and ICU admission. We examined associations between bystander efforts and outcomes using regression, adjusted for age, sex, comorbidities, calendar year and witnessed status...

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

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...

Right-sided infective endocarditis (RSIE) is less common than left-sided infective endocarditis (IE), encompassing only 5-10% of cases of IE. Ninety percent of RSIE involves the tricuspid valve (TV). Given the relatively small numbers of TVIE cases operated on at most institutions, the purpose of this review is to highlight and discuss the current understanding of IE involving the TV. RSIE and TVIE are strongly associated with intravenous drug use (IVDU), although pacemaker leads, defibrillator leads and vascular access for dialysis are also major risk factors...

The implantable cardioverter-defibrillator (ICD) is effective to prevent sudden cardiac death (SCD) in selected patients with heart disease known to be at high risk for ventricular arrhythmia. Nevertheless, this invasive and definitive therapy is not indicated in patients with potentially transient or reversible causes of sudden death, or in patients with temporary contra-indication for ICD placement. The wearable cardioverter defibrillator (WCD) is increasingly used for SCD prevention both in patients awaiting ICD implantation or with an estimated high risk of ventricular arrhythmia though to be transient...

Electrical storm (ES) is a medical emergency characterized by repetitive episodes of sustained ventricular arrhythmias (VAs) in a limited amount of time (at least 3 within a 24-h period) leading to repeated appropriate implantable cardioverter defibrillator therapies. The occurrence of ES represents a major turning point in the natural history of patients with structural heart disease being associated with poor short- and long-term survival particularly in those with compromised left ventricular ejection fraction (LVEF) that can develop hemodynamic decompensation and multi-organ failure...

BACKGROUND: Cardiomyopathy patients are at risk of sudden death, typically from scar-related abnormalities of electrical activation that promote ventricular tachyarrhythmias. Abnormal intra-QRS peaks may provide a measure of altered activation. We hypothesized that quantification of such QRS peaks (QRSp) in high-resolution ECGs would predict arrhythmic events in implantable cardioverter-defibrillator (ICD)-eligible cardiomyopathy patients. METHODS AND RESULTS: Ninety-nine patients with ischemic or non-ischemic dilated cardiomyopathy undergoing prophylactic ICD implantation were prospectively enrolled (age 62±11 years, left ventricular ejection fraction 27±7%)...

This report highlights the importance of realising that even the modern-day implantable cardioverter defibrillators (ICDs) with R wave synchronised appropriate shocks have a potential proarrhythmic effect. We present two cases of ventricular fibrillation induction resulting from an appropriate ICD shock observed in two different patients at our institution. Such cases have not been reported before. We discuss the possible reasons for our observations and are also submitting a pertinent literature review with our reports...
