The subcutaneous implantable cardioverter-defibrillator (S-ICD®, Boston Scientific, Marlborough, MA, USA, previously Cameron Health, San Clemente, CA, USA) represents an important milestone in ICD therapy for prevention of sudden cardiac death (SCD). Since the introduction of the S‑ICD in 2010, the device has undergone further development. Based on the unique feature of an entirely extracardiac implantation, the S‑ICD is able to reduce the common perioperative and long-term complications of the usual endovascular implanted ICD systems...

OBJECTIVES: This study sought to examine the use of the subcutaneous implantable cardioverter-defibrillator (S-ICD) in teenagers and young adults. BACKGROUND: The S-ICD is an important advance in device therapy for the prevention of sudden cardiac death. Although guidelines recommend S-ICD use, long-term data are still limited, especially in subgroups. Therefore, this study analyzed teenagers and young adults <26 years of age with S-ICD in our large single-center S-ICD registry...

Sudden cardiac death (SCD) in an apparently healthy individual is a tragedy. It is important to identify the cause of death and to prevent SCD in potentially at-risk family members. Inherited primary arrhythmia disorders are associated with exercise-related SCD. Despite the well-known benefits of exercise, exercise restriction has been a historical mainstay of therapy for these conditions. However, since familiarity with inherited arrhythmia conditions has increased and patients are often children and young adults, it is necessary to reassess the treatment guidelines regarding exercise constraints...

Sudden cardiac death (SCD) is a major cause of mortality presenting a significant unmet clinical need. Patients at risk of SCD are implanted with implantable cardioverter-defibrillators (ICDs) according to international guidelines based on clinical trial evidence. Implantable cardioverter-defibrillators are not inexpensive and not without problem in terms of inappropriate shocks and infection risk. Also, only a minority of patients implanted with the ICD ever use the device during its battery lifetime highlighting the fact that methods used for SCD risk stratification are inadequate...

Multiple marketing withdrawals due to proarrhythmic concerns occurred in the United States, Canada, and the United Kingdom in the late 1980s to early 2000s. This primer reviews the clinical implications of a drug's identified proarrhythmic liability, the issues associated with these safety-related withdrawals, and the actions taken by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) and by regulatory agencies in terms of changing drug development practices and introducing new nonclinical and clinical tests to asses proarrhythmic liability...

BACKGROUND: Guidelines recommend the use of implanted cardioverter-defibrillators in patients with Brugada syndrome and induced ventricular tachyarrhythmias, but there is no evidence supporting it. OBJECTIVES: This prospective registry study was designed to explore clinical and electrophysiological predictors of malignant ventricular tachyarrhythmia inducibility in Brugada syndrome. METHODS: A total of 191 consecutive selected patients with (group 1; n = 88) and without (group 2; n = 103) Brugada syndrome-related symptoms were prospectively enrolled in the registry...

Over last fifty years, intravenous (iv) phenytoin (PHT) loading dose has been the treatment of choice for patients with benzodiazepine-resistant convulsive status epilepticus and several guidelines recommended this treatment regimen with simultaneous iv diazepam. Clinical studies have never shown a better efficacy of PHT over other antiepileptic drugs. In addition, iv PHT loading dose is a complex and time-consuming procedure which may expose patients to several risks, such as local cutaneous reactions (purple glove syndrome), severe hypotension and cardiac arrhythmias up to ventricular fibrillation and death, and increased risk of severe allergic reactions...

BACKGROUND: International guidelines recommend clinical assessment of the surviving first-degree relatives of sudden cardiac death (SCD) victims to identify a probable cause of death and protect surviving relatives. Only few studies have reported the outcome of clinical management and follow-up of relatives to SCD victims. METHODS: We performed a retrospective cohort study of the clinical and genetic assessment of surviving relatives of SCD victims referred to the Clinic of Inherited Cardiac Diseases at Aarhus University Hospital, Denmark, between 1995 and 2016...

Background: Drug induced long QT syndrome is quite common in daily clinical practice but its impact is unknown. Methods: PubMed and EMBASE databases (until May 2, 2017) were searched to identify studies reporting drug induced long QT syndrome and followed the PRISMA guidelines. The main outcomes measured in these studies were QTc prolongation, ventricular arrhythmias, torsade de pointes (TdP) and death. Results: Out of 176 non-duplicate reports, 36 studies satisfied inclusion criteria and provided data on patients exposed to drugs that can potentially cause long QT...

Background: Patients with acute myocardial infarction (AMI) and bundle-branch block have poor prognoses. The new European Society of Cardiology guideline suggests a primary percutaneous coronary intervention strategy when persistent ischemic symptoms occur in patients with persistent ischemic symptoms and right bundle-branch block (RBBB), but the level of evidence is not high. In fact, the presence of RBBB may lead to the misdiagnosis of transmural ischemia and mask the early diagnosis of ST-elevation myocardial infarction...

Endocrine disorders are associated with various tachyarrhythmias, including atrial fibrillation (AF), ventricular tachycardia (VT), ventricular fibrillation (VF), and bradyarrhythmias. Along with underlying arrhythmia substrate, electrolyte disturbances, glucose, and hormone levels, accompanying endocrine disorders contribute to development of arrhythmia. Arrhythmias may be life-threatening, facilitate cardiogenic shock development and increase mortality. The knowledge on the incidence of tachy- and bradyarrhythmias, clinical and prognostic significance as well as their management is limited; it is represented in observational studies and mostly in case reports on management of challenging cases...

: Implantable cardioverter defibrillators (ICDs) have proven to be the most effective preventive therapy of sudden cardiac death (SCD). Based on current guidelines, the indication for prophylactic ICD therapy is primarily based on a left ventricular ejection fraction (LVEF) less than 35%. However, patients with low LVEF may never have an arrhythmic event while patients with normal to moderately reduced LVEF, who are traditionally felt to be at lower risk, can experience SCD. Therefore, LVEF alone is not an ideal risk stratification parameter to determine ICD therapy...

Sudden cardiac death (SCD), mainly caused by ventricular arrhythmias, is one of the leading causes of mortality in adult congenital heart disease (ACHD) patients. An implantable cardioverter defibrillator (ICD) may prevent SCD, but risk stratification remains challenging. In this review, we will address the current guideline recommendations for ICD implantation in ACHD patients, as well as review a recent study in which the discriminative ability for SCD of these guidelines is evaluated. In this study, the guideline recommendations were applied to patients who died of SCD and living controls...

PURPOSE OF REVIEW: Variant angina, which is characterized by recurrent chest pain and transient ECG changes along with angiographic evidence of coronary artery spasm, generally has a favorable prognosis. However, episodes of ischemia caused by vasospasm may lead to potentially life-threatening ventricular arrhythmias and cardiac arrest, even in patients with no history of prior cardiac disease. This review describes the epidemiology, pathogenesis, clinical spectrum, and management of variant angina, as well as outcomes in patients who present with aborted sudden cardiac death (ASCD)...

We assessed whether male gender was associated with a higher risk of cardiac iron accumulation and fibrosis, heart dysfunction and complications in a large, multicentre cohort of thalassaemia major (TM) patients, in order to optimize the timing in cardiac follow-up. We considered 1711 TM patients (899 females, 31·09 ± 9·08 years), enrolled in the Myocardial Iron Overload in Thalassaemia Network. Clinical/instrumental data are recorded from birth to the first Cardiovascular Magnetic Resonance Imaging scan...

Background Challenging clinical practice guidelines that recommend serum potassium concentration between 4.0-5.0 mEq/L or ≥4.5 mEq/L in patients with acute myocardial infarction, recent studies found increased mortality risks in patients with a serum potassium concentration of ≥4.5 mEq/L. Studies investigating consequences of hypokalemia after acute myocardial infarction revealed conflicting results. Therefore, the aim of this systematic review and meta-analysis was to combine evidence from previous studies on the association of serum potassium concentration with both short and long-term mortality as well as the occurrence of ventricular arrhythmias...

: Cardiac resynchronization therapy (CRT) is an established treatment in patients with symptomatic drug-refractory heart failure and broad QRS complex on the surface ECG. Despite the presence of either mechanical dyssynchrony or viable myocardium at the site where delivering left ventricular pacing being necessary conditions for a successful CRT, their direct assessment by techniques of cardiovascular imaging, though feasible, is not recommended in clinical practice by the current guidelines. Indeed, even though there is growing body of data providing evidence of the additional value of an image-based approach as compared with routine approach in improving response to CRT, these results should be confirmed in prospective and large multicentre trials before their impact on CRT guidelines is considered...

Cardiac sarcoidosis has long been an evasive diagnosis with a spectrum of clinical presentations that extend from asymptomatic to ventricular arrhythmias and sudden cardiac death. The diagnosis has traditionally relied on histology which suffers from the low sensitivity of endomyocardial biopsy due to the patchy nature of the disease in addition to its invasive nature. Due to significant advancements in imaging, it is now possible to accurately identify cardiac sarcoidosis using non-invasive imaging modalities even without histological confirmation...

Sudden cardiac death (SCD) accounts for ∼50% of mortality after myocardial infarction (MI). Most SCDs result from ventricular tachyarrhythmias, and the tachycardias that precipitate cardiac arrest result from multiple mechanisms. As a result, it is highly unlikely that any single test will identify all patients at risk for SCD. Current guidelines for use of implantable cardioverter-defibrillators (ICDs) to prevent SCD are based primarily on measurement of left ventricular ejection fraction (LVEF). Although reduced LVEF is associated with increased total cardiac mortality after MI, the focus of current guidelines on LVEF omits ∼50% of patients who die suddenly...

Idiopathic ventricular tachycardia: Frequent monomorphic premature ventricular contractions or non-sustained ventricular tachycardia without underlying structural heart disease is not a rare condition and may cause significant symptoms. A subgroup of patients develops IVT-associated cardiomyopathy. Current ESC guidelines recommend primary catheter ablation in symptomatic patients with right ventricular outflow tract IVT. Catheter ablation is also recommended in symptomatic patients with a left ventricular outflow tract (or other rare) origin, if antiarrhythmic drugs are ineffective or not desired...
