UNLABELLED: Electrical storm (ES) refers to a life-threatening condition characterised by three or more episodes of ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate implantable cardioverter defibrillator (ICD) shocks in 24 hours. We report a case of a 58-year-old man who suffered recurrent episodes of sustained VT despite appropriate defibrillation and antiarrhythmic drug therapy. On stepwise evaluation, arrhythmogenic right ventricular cardiomyopathy (ARVC) was considered the most likely substrate for his dysrhythmia...

OBJECTIVES: Contrary to advanced cardiac life support guidelines that recommend immediate defibrillation for shockable in-hospital cardiac arrest (IHCA), epinephrine administration before first defibrillation is common and associated with lower survival at a "patient-level." Whether this practice varies across hospitals and its association with "hospital-level" IHCA survival remains unknown. The purpose of this study was to determine hospital variation in rates of epinephrine administration before defibrillation for shockable IHCA and its association with IHCA survival...

INTRODUCTION: Tricuspid regurgitation is associated with significant morbidity and mortality, and occurs at a higher rate in patients with cardiovascular implantable electronic devices. Percutaneous strategies for managing tricuspid regurgitation are evolving, including the development of bicaval valve implantation which has been successfully used in patients with pacing leads. METHODS AND RESULTS: We present the first documented case of lead failure following TricValve® implantation, a dedicated self-expanding system for bicaval valve implantation, and the first successful lead revision procedure in this setting...

BACKGROUND: Early ventricular tachycardia/fibrillation (VT/VF) in patients with ST-elevation myocardial infarction (STEMI) has higher morbidity and mortality. This study examines gender-differentiated risk factors and underlying mechanisms for early onset VT/VF in STEMI. METHODS: We analyzed data from 2,964 consecutive STEMI patients between January 1, 2008 and December 31, 2021. Early VT/VF was defined as occurrence of spontaneous VT/VF of ≥30 s or requirement of immediate cardioversion/defibrillation within the first 48 h after symptoms...

BACKGROUND: During pulseless electrical activity (PEA) the cardiac mechanical and electrical functions are dissociated, a phenomenon occurring in 25-42% of in-hospital cardiac arrest (IHCA) cases. Accurate evaluation of the likelihood of a PEA patient transitioning to return of spontaneous circulation (ROSC) may be vital for the successful resuscitation. THE AIM: We sought to develop a model to automatically discriminate between PEA rhythms with favorable and unfavorable evolution to ROSC...

BACKGROUND: Dilated cardiomyopathy (DCM) caused by Lamin A/C gene (LMNA) mutation is complicated with atrioventricular conduction disturbances, malignant ventricular arrhythmias and progressive severe heart failure. OBJECTIVE: We hypothesized that early cardiac resynchronization therapy (CRT) implantation in LMNA mutation carriers with an established indication for pacemaker or implantable cardioverter defibrillator (ICD), may preserve ejection fraction, and delay disease progression to end stage heart failure...

AIM: We aimed to describe trends in the incidence and outcomes of refractory ventricular fibrillation (RVF) compared to non-refractory ventricular fibrillation (non-RVF) in out-of-hospital cardiac arrest (OHCA). METHODS: Between 2010 and 2019, we included all OHCA cases involving adults ≥ 16 years old with an initial shockable rhythm and who received an attempted resuscitation by Emergency Medical Services (EMS) or a bystander shock prior to EMS arrival in Victoria, Australia...

BACKGROUND: Current cohorts of idiopathic ventricular fibrillation (IVF) patients primarily include adult-onset patients. Underlying causes of a sudden cardiac arrest vary with age, therefore underlying causes and disease course may differ for adolescent-onset versus adult-onset patients. OBJECTIVE: To compare adolescent-onset with adult-onset patients with an initially unexplained cause for VF. METHODS: This study includes 39 patients with an index event ≤19 years (adolescent-onset) and 417 adult-onset patients from the Dutch Idiopathic VF registry...

BACKGROUND: Atrial high-rate episodes (AHRE) are frequent in patients with cardiac implantable electronic devices. A decrease in device-detected P-wave amplitude may be an indicator of periods of increased risk of AHRE. OBJECTIVE: To assess the association between P-wave amplitude and AHRE incidence. METHODS: Remote monitoring data from 2,579 patients with no history of atrial fibrillation (23% pacemakers, 77% implantable cardioverter-defibrillators [ICDs] of which 40% providing cardiac resynchronization therapy [CRT]) were used to calculate the mean P-wave amplitude during 1 month after implantation...

PURPOSE OF REVIEW: Tricuspid regurgitation is a commonly encountered valvular pathology in patients with trans-tricuspid pacing or implantable cardioverter-defibrillator leads. Transcatheter tricuspid valve interventions are increasingly performed in patients at high surgical risk. Implantation of these valves can lead to the "jailing" of a trans-tricuspid lead. This practice carries both short- and long-term risks of lead failure and subsequent infection without the ability to perform traditional transvenous lead extraction...

A 40-year-old man, newly diagnosed with cardiac sarcoidosis (CS) presented with symptomatic ventricular tachycardia three days after starting steroid-based immunosuppressive therapy (IT). There was no clear guideline indication for implantable cardioverter-defibrillator (ICD) before the initiation of IT. Shortly after ICD implantation and the initiation of anti-arrhythmic drugs, recurring ventricular arrhythmias required titration of the anti-arrhythmic drug therapy. One-year follow-up assessment showed no significant arrhythmias and complete PET scan FDG uptake suppression...

Obesity condition causes morphological and functional alterations involving the cardiovascular system. These can represent the substrates for different cardiovascular diseases, such as atrial fibrillation, coronary artery disease, sudden cardiac death, and heart failure (HF) with both preserved ejection fraction (EF) and reduced EF. Different pathogenetic mechanisms may help to explain the association between obesity and HF including left ventricular remodelling and epicardial fat accumulation, endothelial dysfunction, and coronary microvascular dysfunction...

BACKGROUND: Many patients with mild to moderately reduced left ventricular ejection fraction (LVEF) that require permanent pacemaker (PPM) implantation do not have a concurrent indication for implantable cardioverter-defibrillator (ICD) therapy. However, the risk of ventricular tachycardia/fibrillation (VT/VF) in this population is unknown. OBJECTIVE: To describe the risk of VT/VF following PPM implantation in patients with mild to moderately reduced LVEF. METHODS: Retrospective analysis was performed on 243 patients with LVEF between 35-49% who underwent PPM placement, and did not meet indications for an ICD...

Magnetic resonance imaging (MRI) is now an indispensable diagnostic tool in medicine due to its outstanding contrast resolution and absence of radiation exposure, enabling detailed tissue characterization and three-dimensional anatomical representation. This is especially important when evaluating individuals with congenital heart disease (CHD) who frequently require cardiac implantable electrical devices (CIEDs). While MRI safety issues have previously limited its use in patients with CIEDs, new advances have called these limitations into question...

BACKGROUND: Despite modern techniques for ablation of ventricular tachycardia (VT), the procedure faces challenges such as deep intramural substrates or inaccessibility of the pericardial space. We aim to present a case of successful surgical treatment of a patient with drug-refractory VT, an apical aneurysm, large left ventricular (LV) thrombus, and recurrent implantable cardioverter defibrillator (ICD) shocks following failed epicardial catheter ablation.

Inappropriate shocks from an Intracardiac defibrillator are associated with increased mortality and may be caused by external electromagnetic interference. This case illustrates that water is an excellent conductor of electricity and that determined investigation may reveal the cause of inappropriate shocks.
