CLINICAL INTRODUCTION: A man in his early 30s with remote history of a febrile rash as a toddler presented to the emergency room following an out-of-hospital cardiac arrest while riding his bicycle. He received bystander cardiopulmonary resuscitation and one shock from an automatic external defibrillator, successfully restoring sinus rhythm. On arrival, he was haemodynamically stable without ECG evidence of ST segment changes to suggest active ischaemia, and an initial troponin I was mildly elevated at 0...

BACKGROUND: Patients with an implantable cardioverter defibrillator (ICD) retain a scar and a bump at the site of implant. This may lead to body image concerns (BICs) that influence patients' quality of life. Few studies have examined the prevalence and impact of BICs post implant, prompting us to conduct a scoping review of the field. METHODS: We searched the Medline, Embase, PsycINFO and Cinahl databases in August 2016 and repeated May 2017. Included were studies reporting on patients ≥ 18 years, an ICD implant (transvenous, subcutaneous, or ICD with cardiac resynchronization therapy (CRT-D), reporting on BICs, and published in peer-reviewed English-language journals...

BACKGROUND: Implantable cardioverter-defibrillator (ICD) is the most effective therapy currently available to prevent sudden cardiac death (SCD) in patients with left ventricular (LV) dysfunction. Although LV ejection fraction (LVEF) is an excellent marker of SCD in these patients, but determining other predictors might help to identify patients who will be benefit more from device implantation. The purpose of this study was to determine whether abnormal LV sphericity index (SI) in transthoracic echocardiography is associated with appropriate ICD therapy in these patients...

Data on cardiovascular disease, including arrhythmias, in Africa is limited. However, the burden of cardiovascular disease appears to be on the rise. Recent global data suggests an increase in atrial fibrillation rates despite declining rates of rheumatic heart disease. Atrial fibrillation is also associated with increased mortality in Africa. Current management with medical therapy is sub-optimal and ablation procedures, inaccessible. Atrial fibrillation is also an independent risk factor for death in patients with rheumatic heart disease...

Introduction: Sudden cardiac death (SCD) of young athletes during competition or training is a tragic event. The long QT syndrome (LQTS) is an arrythmogenic disorder characterized by prolonged ventricular repolarization leading to torsade de pointes evident at electrocardiogram (ECG). Implantable cardioverter defibrillator is an option to revert ventricular fibrillation to sinus rhythm, although the implantation may result in denial of sports participations to the athlete. The authors reviewed the current literature on LQTS in young athletes, to clarify the role of different screening technologies to prevent SCD...

OBJECTIVES: The goal of this study was to explore the association between exercise duration versus exercise intensity and adverse outcome in patients with arrhythmogenic cardiomyopathy (AC). BACKGROUND: Vigorous exercise aggravates and accelerates AC, but there are no data assessing the harmful effects of exercise intensity and duration in these patients. METHODS: Exercise habits at time of diagnosis were recorded by standardized interviews in consecutive AC patients...

BACKGROUND: Classical fluoroscopic criteria for the documentation of septal right ventricular (RV) lead positioning have poor accuracy. We sought to evaluate the individualized left anterior oblique (LAO) projection as a novel fluoroscopy criterion. METHODS: Consecutive patients undergoing pacemaker or defibrillator implantation were prospectively included. RV lead positioning was assessed by fluoroscopy using posteroanterior, right anterior oblique 30° to rule out coronary sinus positioning, and LAO 40° in the classical group or individualized LAO in the individualized group...

BACKGROUND:  A wearable cardioverter-defibrillator (WCD) can terminate ventricular fibrillation and ventricular tachycardias via electrical shock and thus give transient protection from sudden cardiac death. We investigated its role after cardiac surgery. METHODS:  We retrospectively analyzed all patients who were discharged with a WCD from cardiac surgery department. The WCD was prescribed for patients with a left ventricular ejection fraction (LVEF) of ≤35% or an explanted implantable cardioverter-defibrillator (ICD)...

A 62 year old male presented to his treating cardiologist for routine interrogation of his implantable cardiac defibrillator (ICD) on the background of severe ischaemic cardiomyopathy and end-stage kidney disease on haemodialysis. The device log revealed multiple paroxysms of atrial fibrillation (AF); however, upon scrutinising these episodes it was evident that they always corresponded to episodes of haemodialysis whilst dialysing through a chronic dialysis catheter, but not whilst dialysing via an arteriovenous fistula...

Death in patients with postinfarction aneurysms of the left ventricle (LV) is mainly caused by life-threatening ventricular arrhythmias - ventricular tachycardias (VTs) and ventricular fibrillations (VFs). Surgical reconstruction of the LV may potentially lead to disruption of the re-entry mechanism, lying at the basis of ventricular tachyarrhythmias. A series of authors demonstrated high efficacy of such procedures as endocardectomy and radiofrequency ablation of the borderline zone of the LV. But high incidence of relapses, difficulty detecting the localization of VT and performing radiofrequency ablation (RFA), as well as high incidence of spontaneous and induced VTs in patients with postinfarction aneurysms of the LV have preserved dissatisfaction with the currently existing techniques...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare cardiovascular disease that predisposes to ventricular arrhythmias potentially leading to sudden cardiac death (SCD). ARVC varies considerably with multiple clinical presentations, ranging from no symptoms to cardiac arrhythmias to SCD. ARVC prevalence is not well known, but the estimated prevalence in the general population is 1:5000. Diagnosis of ARVC can be made by using the Revised European Society of Cardiology criteria for ARVC that includes ventricular structural and functional changes, ECG abnormalities, arrhythmias, family and genetic factors...

Mostly Streptococcus bovis ( S. bovis ) bacteremia and endocarditis (60%) has been found to be associated with underlying colorectal cancer (CRC). Enterococcus faecalis ( E. faecalis ) bacteremia and endocarditis has no identifiable source in most of the cases. E. faecalis is part of normal gut flora that can translocate through the intestine and cause the systemic infection. With any intestinal lesion or tumor, the barrier is breached and the gut flora like E. faecalis can translocate and cause infection. A 55-years-old male known to have non-ischemic cardiomyopathy with implantation of automated implantable cardioverter defibrillator (AICD) and atrial fibrillation presented with weight loss, fever and back pain...

BACKGROUND: Postmortem interrogations of cardiac implantable electronic devices (CIEDs), recommended at autopsy in suspected cases of sudden cardiac death, are rarely performed, and data on systematic postmortem CIED analysis in the forensic pathology are missing. The aim of the study was to determine whether nonselective postmortem CIED interrogations and data analysis are useful to the forensic pathologist to determine the cause, mechanism, and time of death and to detect potential CIED-related safety issues...

OBJECTIVES: Just-in-time training (JITT) is a method of simulation-based training where the training occurs within the clinical environment in a concise manner. Just-in-time training has shown effects at the learner, patient, and system-wide levels. We evaluated a JITT curriculum for the procedures of intraosseous (IO) needle placement and defibrillator use in a pediatric emergency department (ED) by comparing the trainees' comfort level in performing those procedures independently (Kirkpatrick level 2a) and trainees' knowledge of the procedures/equipment (Kirkpatrick level 2b) before and after the JITT...
