BACKGROUND: The development of athlete-specific electrocardiogram (ECG) interpretation standards, along with recent rates of sudden cardiac death (SCD) in athletes being higher than previously estimated, has heightened the debate in the sports medicine community regarding cardiovascular screening of the college athlete, including whether certain high-risk subsets, such as male basketball athletes, should undergo more intensive screening. HYPOTHESIS: ECG and/or echocardiography screening in National Collegiate Athletic Association Autonomous 5 Division I (A5DI) schools will be more common than previous reports, and there will be more frequent use of noninvasive cardiac screening for men's basketball players than the general athlete population...

The article is based on the case analysis of a sudden and unexpected intraoperative death of a 51-year-old female patient with hypertrophic cardiomyopathy, who was undergoing a non-cardiac operation in a non-cardiosurgery clinic, from acute precipitation of left ventricular outflow tract obstruction provoked by surgery and anesthesia. It emphasizes the importance of raising non-cardiac anesthesiologists' awareness of the issue and having clear standards of pre-operative evaluation and perioperative management of patients with hypertrophic cardiomyopathy in order to avoid fatal medical errors...

Mutations leading to disorders within ion (mainly potassium and sodium) channels, have different degrees of expression in the brain and in the heart, which can cause simultaneous occurrence of disorders in both organs. This is manifested by the occurrence of epileptic seizures and cardiac electrical disturbances, further exacerbated by stimulation of autonomic structures within the central nervous system. In all patients with unclear paroxysmal disorders, and in those with unexplained sudden cardiac death, consideration should be given to the possibility of occurrence of genetically determined disorders in the ion channels...

Long QT syndrome (LQT) represents a heterogeneous family of cardiac electrophysiologic disorders characterized by QT prolongation and T-wave abnormalities on the electrocardiogram. It is commonly associated with syncope, however, sudden cardiac death can occur due to torsades de pointes. LQT is a clinical diagnosis and should be suspected in individuals on the basis of clinical presentation, family history and electrocardiogram characteristics. Management is focused on the prevention of syncope and ultimately sudden death...

Cardiovascular imaging has radically changed the management of patients with arrhythmogenic cardiomyopathies. This article focuses on the role of echocardiography and MRI in the diagnosis of these structural diseases. Cardiomyopathies with hypertrophic pattern (hypertrophic cardiomyopathy, restrictive cardiomyopathies, amyloidosis, Anderson-Fabry disease, and sarcoidosis), cardiomyopathies with dilated pattern, inflammatory cardiac diseases, and right ventricular arrhythmogenic cardiomyopathy are analyzed. Finally, anatomic predictors of arrhythmias and sudden cardiac death are discussed...

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 histologic examination revealed a pericardial cyst located in the posterior mediastinum...

Sudden cardiac death (SCD) is the non-traumatic death, due to loss of heart function that occurs suddenly and unexpectedly within 6 hours of a previously normal state of health. It is related to intense competitive sports promoting ventricular tachycardia (VT)/ventricular fibrillation (VF) in the presence of underlying abnormal substrate. A serial evaluation of cardiac physiologic changes taking place during training will allow the better understanding of athlete's heart and will facilitate its discrimination from other gray-zone cardiomyopathies...

BACKGROUND: Ventricular tachycardia or fibrillation (VT/VF) is a major cause of sudden cardiac death after acute myocardial infarction (AMI). This study aims to investigate the clinical characteristics and outcomes of VT/VF, to identify the variables associated with VT/VF, and to construct a new scoring system. METHODS: Patients with relatively preserved left ventricular ejection fraction (LVEF) (≥40%) included in the Korea Acute Myocardial Infarction Registry-National Institutes of Health registry were enrolled in this study...

Marine n-3 PUFA may improve autonomic dysfunction by an increase in heart rate variability (HRV) and may reduce the risk of malignant ventricular arrhythmias. Only a few smaller studies have examined such effects in patients on chronic dialysis, who often have autonomic dysfunction and a high risk of sudden cardiac death, which accounts for almost 30 % of all deaths. This cross-sectional study investigated the association between the plasma phospholipid content of n-3 PUFA and 24-h HRV or ventricular arrhythmias in patients on chronic dialysis...

The populations of Asian countries are expected to age rapidly in the near future, with a dramatic increase in the number of heart failure (HF) patients also anticipated. The need for palliative and end-of-life care for elderly patients with advanced HF is currently recognized in aging societies. However, palliative care and active treatment for HF are not mutually exclusive, and palliative care should be provided to reduce suffering occurring at any stage of symptomatic HF after the point of diagnosis. HF patients are at high risk of sudden cardiac death from the early stages of the disease onwards...

Recent clinical studies have revealed a new hypertrophic cardiomyopathy-associated mutation (F87L) in the central region of human cardiac troponin T (TnT). However, despite its implication in several incidences of sudden cardiac death in young and old adults, whether F87L is associated with cardiac contractile dysfunction is unknown. Because the central region of TnT is important for modulating the muscle length-mediated recruitment of new force-bearing cross-bridges (XBs), we hypothesize that the F87L mutation causes molecular changes that are linked to the length-dependent activation of cardiac myofilaments...

BACKGROUND AND OBJECTIVES: Cardiac tamponade is potentially fatal medical condition, which rarely occurs as a complication of lung lobectomy. We present the first case of cardiac tamponade to develop in a Post-Anesthesia Care Unit following a lung lobectomy. CASE REPORT: A 54-year-old man with pulmonary squamous cell carcinoma underwent an apparently uncomplicated lung lobectomy. His hemodynamics was unremarkable throughout the surgery and initially in the Post-Anesthesia Care Unit...

BACKGROUND: Culprit coronary atherosclerotic plaques (APs) from young sudden cardiac death (SCD) victims are mostly non-atheromatous, i.e., consisting of proliferative smooth muscle cells (SMCs). Coronary vasospasm has been advocated to explain plaque instability in the absence of thrombosis. Our aim was to characterize the SMC phenotype in the intima and media of coronary arteries from young SCD victims. METHODS AND RESULTS: A total of 38 coronary artery segments were studied: (a) 18 APs from young (≤40 years old) SCD patients, (b) 9 APs from old (>40 years old) SCD patients, (c) 11 non-atherosclerotic coronary arteries from young patients (≤40 years old)...

Excessive death of cardiac myocytes leads to multiple cardiac diseases, including myocardial infarction, arrhythmia, heart failure and sudden cardiac death. For the last several decades, most work on cell death has focused on apoptosis, which is generally considered as the only form of regulated cell death, whereas necrosis has been regarded to be an unregulated process. Recent findings reveal that necrosis also occurs in a regulated manner and that it is closely related to the physiology and pathophysiology of multiple organs, including the heart...

BACKGROUND: Right ventricular systolic dysfunction (RVD) often coexists with various cardiopulmonary diseases. However, the association between RVD and risk of sudden cardiac death (SCD) has not been well studied. This study examined the risk of SCD associated with RVD in patients with heterogeneous underlying cardiac diseases. METHODS: The Mayo Clinic cardiac care unit database included 5463 consecutive patients with complete echocardiographic evaluation to assess right ventricular systolic function and RVD severity...

RATIONALE: Infantile-onset hypertrophic cardiomyopathy (HCMP) should be considered a largely genetic condition, although its onset is most often triggered by infection. Very long chain acyl-CoA dehydrogenase (VLCAD) deficiency is a rare autosomal recessive inborn error of mitochondrial fatty acid β-oxidation that often causes severe cardiomyopathy and/or sudden death during the neonatal period. PATIENT CONCERNS: Herein, we report an infant with VLCAD deficiency who presented with severe cardiac manifestations, including massive pericardial effusion and HCMP...
