Research Progress of Sudden Cardiac Death in Forensic Medicine.

Sudden death (SD) is a special kind of death owing to disease, which severely threatening the lives of community population. As the most common type of SD, sudden cardiac death (SCD) has always been a crucial content of identification and research in forensic pathology. This article reviews the research progress from the aspects of epidemiology, morphology, molecular pathology and virtual anatomy of SCD in forensic medicine, so as to provide a reference for the morphological identification, determin...

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...

Incomplete Penetrance and Variable Expressivity: Hallmarks in Channelopathies Associated with Sudden Cardiac Death.

Sudden cardiac death is defined as an unexpected decease of cardiac origin. In individuals under 35 years old, most of these deaths are due to familial arrhythmogenic syndromes of genetic origin, also known as channelopathies. These familial cardiac syndromes commonly follow an autosomal dominant pattern of inheritance. Diagnosis, however, can be difficult, mainly due to incomplete penetrance and variable expressivity, which are hallmarks in these syndromes. The clinical manifestation of these diseases can ...

Risk of sudden cardiac death in relation to season-specific cold spells: a case-crossover study in Finland.

To test a priori hypothesis of an association between season-specific cold spells and sudden cardiac death (SCD).

Repolarization abnormalities unmasked with exercise in sudden cardiac death survivors with structurally normal hearts.

Models of cardiac arrhythmogenesis predict that non-uniformity in repolarization and/or depolarization promotes ventricular fibrillation and is modulated by autonomic tone, but this is difficult to evaluate in patients. We hypothesize that such spatial heterogeneities would be detected by non-invasive ECG imaging (ECGi) in sudden cardiac death (SCD) survivors with structurally normal hearts under physiological stress.

Aborted sudden cardiac death in a patient with implantable loop recorder.

We discuss a 46-year-old man with history of hypertension and inferior wall myocardial infarction and mild left ventricular dysfunction who presented with aborted sudden cardiac death due to episodes of ventricular tachyarrhythmia detected by a Reveal-LINQ which had been implanted one year prior to presentation.

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.

Sudden cardiac death and pump failure death prediction in chronic heart failure by combining ECG and clinical markers in an integrated risk model.

Sudden cardiac death (SCD) and pump failure death (PFD) are common endpoints in chronic heart failure (CHF) patients, but prevention strategies are different. Currently used tools to specifically predict these endpoints are limited. We developed risk models to specifically assess SCD and PFD risk in CHF by combining ECG markers and clinical variables.

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.

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.

Tpeak-Tend interval during therapeutic hypothermia can predict upcoming ventricular fibrillation in subjects with aborted arrhythmic sudden cardiac death: 3-years follow-up results.

Prolonged Tpeak-Tend interval has been shown to be markers of arrhythmogenesis in various cardiac disorders. However, its dynamicity is one of the obstacles to predict fatal ventricular arrhythmia. This study investigated whether Tpeak-Tend interval during therapeutic hypothermia (TH) is associated with ventricular fibrillation (VF) inducibility and clinical arrhythmia in subjects with aborted arrhythmic sudden cardiac death (SCD).

Association between mitochondrial DNA copy number and sudden cardiac death: findings from the Atherosclerosis Risk in Communities study (ARIC).

Sudden cardiac death (SCD) is a major public health burden. Mitochondrial dysfunction has been implicated in a wide range of cardiovascular diseases including cardiomyopathy, heart failure, and arrhythmias, but it is unknown if it also contributes to SCD risk. We sought to examine the prospective association between mtDNA copy number (mtDNA-CN), a surrogate marker of mitochondrial function, and SCD risk.

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 ...

Sudden Cardiac Arrest during Participation in Competitive Sports.

The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes.

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.

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...

Signalling the risk of sudden cardiac death: the ECG and beyond.

Non-ischaemic cardiomyopathy, sudden death and implantable defibrillators: a review and meta-analysis.

The recent Danish Study to Assess the Efficacy of ICDs in Patients with Non-ischemic Systolic Heart Failure on Mortality (DANISH) trial suggested that implantable cardioverter defibrillators (ICDs) do not reduce overall mortality in patients with non-ischaemic cardiomyopathy (NICM), despite reducing sudden cardiac death. We performed an updated meta-analysis to examine the impact of ICD therapy on mortality in NICM patients.

Cardiac sarcoidosis: diagnostics, treatment and follow-up.

Sarcoidosis is a generalised granulomatous disorder of unknown aetiology. Cardiac involvement may affect conduction system, myocardium, valvular apparatus and pericardium. Clinical spectrum ranges from asymptomatic involvement to sudden cardiac death. Patients with biopsy-proven extracardiac sarcoidosis should be screened for cardiac involvement (standard ECG, 24-hour Holter ECG, echocardiography) and in case of any abnormalities found on these tests, more advanced diagnostic methods should be used. Steroid...

Novel Pharmacotherapy in Hypertrophic Cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is an inherited disease characterized by unexplained left ventricular hypertrophy. Although it is estimated to affect 1 out of 500 people, the HCM gene carrier prevalence is much more common, probably as high as 1 in 200 people. Most affected individuals have a normal life expectancy, while some patients may develop sudden cardiac death or end-stage heart failure. Despite significant developments in the treatment of HCM with surgical, interventional, and device-based proced...
