Outcomes of Cardiac Screening in Adolescent Soccer Players.

Background Reports on the incidence and causes of sudden cardiac death among young athletes have relied largely on estimated rates of participation and varied methods of reporting. We sought to investigate the incidence and causes of sudden cardiac death among adolescent soccer players in the United Kingdom. Methods From 1996 through 2016, we screened 11,168 adolescent athletes with a mean (±SD) age of 16.4±1.2 years (95% of whom were male) in the English Football Association (FA) cardiac screening progra...

Sudden Cardiac and Noncardiac Death in Sports: Epidemiology, Causes, Pathogenesis, and Prevention.

Although few doubts remain that physical exercise should be widely promoted for maintenance of health and fitness, the risk of adverse events such as sudden death (especially due to cardiac causes, i.e., sudden cardiac death [SCD]) during exercise remains tangible. The overall risk of sudden death in athletes is relatively low (i.e., usually comprised between 0.1 and 38/100,000 person-years), and globally comparable to that of the general population. However, up to 20% of all sudden death cases are still re...

Current Perspectives on Sudden Cardiac Death in Hemodialysis Patients.

Recent lines of evidence suggest that, as in other countries, sudden cardiac death (SCD) is more common in the Japanese dialysis clinical setting than we previously thought.

A novel familial truncating mutation in the filamin C gene associated with cardiac arrhythmias.

The authors report for the first time a novel mutation in the FLNC gene associated with cardiac arrhythmias in two half-siblings. The FLNC gene on chromosome 7q32 encodes filamin C, which stabilizes the actin network within the cardiomyocyte. The proband is an 8-year-old asymptomatic patient with frequent premature ventricular contractions noted on serial monitoring. Interestingly, the proband and his half-brother harbored a heterozygous 13 base pair deletion that resulted in a frameshift mutation and intro...

Sudden Cardiac Death in Hypertrophic Cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is a heart disease characterized by hypertrophy of the left ventricular myocardium and is most often caused by mutations in sarcomere genes. The structural and functional abnormalities are not explained by flow-limiting coronary artery disease or loading conditions. The disease affects at least 0.2% of the population worldwide and is the most common cause of sudden cardiac death in young people and competitive athletes because of fatal ventricular arrhythmia. In some patien...

Pericardial Cyst: Cause of Sudden Cardiac Death?

Cardiovascular disease is the leading cause of sudden death in the world. The etiology of sudden cardiac death involves a wide range of diseases, but seldom pericardial cysts. A pericardial cyst is an uncommon cyst usually located in the middle mediastinum and rarely in the posterior part. They are usually harmless and asymptomatic. Here, we present a case of a 63-year-old woman who presented with dyspnea and hoarseness, but died suddenly after a CT scan was attempted. The detailed forensic pathologic and h...

Sudden Unexpected Death From Unusually Large Primary Cardiac B-cell Lymphoma.

Primary cardiac lymphomas represent approximately 1% to 2% of primary cardiac neoplasms and 5% of malignant cardiac neoplasms. Here we present a case of sudden unexpected death of a middle-aged male resulting from an unusually large cardiac B-cell lymphoma. The neoplasm infiltrated the myocardium of the right atrium and ventricle and, to a lesser extent, the wall of the left atrium and pulmonary trunk. Extensive infiltration of the heart by the primary cardiac lymphoma, combined with the complete lack of sy...

Strangulation of the heart presenting as sudden cardiac death: A deadly but forgotten complication of epicardial pacing device.

Strangulation of the heart appears to be an exceedingly rare mechanical phenomenon that can develop with epicardial pacing wires in individuals undergoing somatic growth. Over the passage of time, owing to size mismatch between a fixed wire length and dynamically growing heart, the epicardial wire may embed around the heart resulting in the progressive over-pressurizing of involved cardiac structures. Depending on the location of the peak constriction pressures, cardiac strangulation may damagingly affect c...

Post-mortem ICD interrogation in mode of death classification.

The definition of sudden death due to arrhythmia relies on the time interval between onset of symptoms and death. However, not all sudden deaths are due to arrhythmia. In patients with an implantable cardioverter defibrillator (ICD) post-mortem device interrogation may help better distinguish the mode of death compared to a time-based definition alone.

Molecular autopsy in a cohort of infants died suddenly at rest.

Sudden infant death syndrome is the leading cause of death during the first year of life. A large part of cases remains without a conclusive cause of death after complete autopsy. In these situations, cardiac arrhythmia of genetic origin is suspected as the most plausible cause of death. Our aim was to ascertain whether genetic variants associated with sudden cardiac death might be the cause of death in a cohort of infants died suddenly. We analyzed 108 genes associated with sudden cardiac death in 44 post-...

Management of sudden cardiac death in cardiac sarcoidosis using the wearable cardioverter defibrillator.

Patients with cardiac sarcoidosis are at increased risk of ventricular tachycardia/fibrillation.

The Pēpi-Pod study: Overnight video, oximetry and thermal environment while using an in-bed sleep device for sudden unexpected death in infancy prevention.

The aim of this study was to identify the potential risks and benefits of sleeping infants in a Pēpi-Pod distributed to families with high risk of sudden unexpected death in infancy compared to a bassinet.

The nightmare ECG of a spontaneously aborted sudden cardiac death.

We present the case of a spontaneously aborted sudden cardiac death related to an high-rate ventricular tachycardia in an healthy man with bileaflet mitral valve prolapse. An effective treatment of the patient, with complete suppression of ventricular ectopic activity, was achieved only combining medical therapy, ICD and catheter ablation, thus overcoming the limitations of each approach.

Sleep duration and risk of fatal coronary heart disease, sudden cardiac death, cancer death and all-cause mortality.

Sleep duration has been shown to be associated with all-cause mortality, however its relationship with cause-specific fatal events remains uncertain. We examined the relationship between sleep duration and risk of fatal coronary heart disease (CHD), sudden cardiac death, cancer related death and all-cause mortality.

Atrial fibrillation is associated with sudden cardiac death: a systematic review and meta-analysis.

Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD.

Emerging Implications of Genetic Testing in Inherited Primary Arrhythmia Syndromes.

Inherited primary arrhythmia syndromes are genetically determined disorders of cardiac ion channels or ion channel macromolecular complexes usually associated with a higher risk of sudden cardiac death. These conditions have a very broad spectrum of clinical manifestations, ranging from an asymptomatic course to syncope, atrial and ventricular arrhythmias, and conduction disturbances, but may produce sudden infant death syndrome and unexplained sudden cardiac death in apparently healthy individuals. During ...

Effectiveness of drug interventions to prevent sudden cardiac death in patients with heart failure and reduced ejection fraction: an overview of systematic reviews.

To summarise and synthesise the current evidence regarding the effectiveness of drug interventions to prevent sudden cardiac death (SCD) and all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF).

TpTe and TpTe/QT: novel markers to predict sudden cardiac death in ESRD?

Reliable markers to predict sudden cardiac death (SCD) in patients with end stage renal disease (ESRD) remain elusive, but echocardiogram (ECG) parameters may help stratify patients. Given their roles as markers for myocardial dispersion especially in high risk populations such as those with Brugada syndrome, we hypothesized that the Tpeak to Tend (TpTe) interval and TpTe/QT are independent risk factors for SCD in ESRD.

Obstructive Sleep Apnea Increases Sudden Cardiac Death in Incident Hemodialysis Patients.

Mortality in end-stage renal disease (ESRD) occurs predominantly from cardiovascular disease (CVD) and sudden cardiac death (SCD). Obstructive sleep apnea (OSA) is characterized by periodic airflow limitation associated with sleep arousal and oxygen desaturation and is prevalent in patients with ESRD. Whether OSA increases the risk for SCD, cardiovascular and all-cause mortality among hemodialysis patients remains unknown.

Dysautonomy in different death risk groups (rassi score) in patients with chagas heart disease.

It has been difficult to prove that the "catecholamine-induced cardiomyopathy" contributes to the mechanism of sudden cardiac death in Chagas heart disease. Also, it is almost impossible to rule out the possibility that is not involved in the process. More importantly, the vagal-cholinergic pathway in the ventricle plays a direct role in the prevention of the initiation of complex ventricular arrhythmias, including non-sustained ventricular tachycardia, ventricular fibrillation responsible for sudden death.

Postmortem Genetic Testing for Cardiac Ion Channelopathies in Stillbirths.

Although stillbirth is a significant health problem worldwide, the definitive cause of death remains elusive in many cases, despite detailed autopsy. In this study of partly explained and unexplained stillbirths, we used next-generation sequencing to examine an extended panel of 35 candidate genes known to be associated with ion channel disorders and sudden cardiac death.

Change of sensing vector in the subcutaneous ICD during follow-up and after device replacement.

The subcutaneous implantable cardioverter defibrillator (S-ICD) has been established as a valuable alternative to transvenous ICD for prevention of sudden cardiac death. The system automatically chooses the optimal sensing vector. However, during follow-up and especially after device replacement we observed a change of the suggested sensing vector in automatic setup. Therefore, we analyzed frequency and reasons of vector change and its impact on inappropriate shocks (iAS).

Appropriate Classification and Filtering of Electromagnetic Interference by the S-ICD Sensing Algorithm During Surgery.

The subcutaneous implantable cardioverter defibrillator (S-ICD) is a new device used for the prevention of sudden cardiac death. Best practices in the perioperative management of the S-ICD are not established; therefore, clinicians typically deactivate the device during surgery, with reinterrogation and activation postoperatively. This could put the patient at risk for being discharged with the device "off." We present two cases where electromagnetic interference was appropriately detected by the S-ICD and ...

Severe Hypoglycemia-Induced Sudden Death is Mediated by Both Cardiac Arrhythmias and Seizures.

We previously demonstrated that insulin induced severe hypoglycemia associated sudden death is largely mediated by fatal cardiac arrhythmias. In the current study, a pharmacological approach was taken to explore the potential contribution of hypoglycemic seizures and the sympathoadrenergic system in mediating severe hypoglycemia associated sudden death. Adult Sprague Dawley rats were randomized into one of four treatment groups: 1) saline (SAL), 2) anti-arrhythmic (β1 blocker atenolol), 3) anti-seizure (Le...

Early prognostic value of an Algorithm based on spectral Variables of Ventricular fibrillAtion from the EKG of patients with suddEn cardiac death: A multicentre observational study (AWAKE).

Ventricular fibrillation (VF)-related sudden cardiac death (SCD) is a leading cause of mortality and morbidity. Current biological and imaging parameters show significant limitations on predicting cerebral performance at hospital admission. The AWAKE study (NCT03248557) is a multicentre observational study to validate a model based on spectral ECG analysis to early predict cerebral performance and survival in resuscitated comatose survivors.
