Takayasu arteritis is an uncommon inflammatory disease with usually a good prognosis. However, sometimes, the evolution can be fatal essentially by a coronary arteries involvement. We present a case of a 19-year-old woman who died suddenly from cardiogenic shock complicating an unknown Takayasu arteritis.At the autopsy, the aorta showed a significant thickening of the wall. The coronary arteries were slightly thickened and did not show any occlusion. Microscopic examination of the aorta showed an abundant granulomatous and a lymphoplasmacytic infiltrate...

Sudden cardiac death (SCD) is the leading cause of death. The current paradigm in SCD requires the presence of an abnormal myocardial substrate and an internal or external transient factor that triggers cardiac arrest. Based on prior mechanistic evidence, we hypothesized that an unusually cold weather event (a cold spell) could act as an external factor triggering SCD. We tested potential effect modification of prior diagnoses and select pharmacological agents disrupting pathological pathways between cold exposure and death...

OBJECTIVE: Among primary prevention patients with heart failure receiving cardiac resynchronisation therapy (CRT), the impact of additional implantable cardioverter defibrillator (ICD) treatment on outcomes and its interaction with sex remains uncertain. We aim to assess whether the addition of the ICD functionality to CRT devices offers a more pronounced survival benefit in men compared with women, as previous research has suggested. METHODS: Observational multicentre cohort study of 5307 consecutive patients with ischaemic or non-ischaemic dilated cardiomyopathy and no history of sustained ventricular arrhythmias having CRT implantation with (cardiac resynchronisation therapy defibrillator (CRT-D), n=4037) or without (cardiac resynchronisation therapy pacemaker (CRT-P), n=1270) defibrillator functionality...

BACKGROUND: Cardiovascular autonomic neuropathy (CAN) increases morbidity and mortality in diabetes through association with a high risk of cardiac arrhythmias and sudden death, possibly related to silent myocardial ischemia. During the sub-clinical stage, CAN can be detected through reduction in heart rate variability (HRV). The aim of our study was to estimate if the time and frequency-domain analysis can be valuable for detecting CAN in young patients with type 1 diabetes mellitus (T1DM)...

Hypertrophic cardiomyopathy (HCM) is a common heart disease with a prevalence of 1 in 500 in the general population. Several mutations in genes encoding cardiac proteins have been found in HCM patients, but these changes do not predict occurrence or prognosis and the molecular mechanisms underlying HCM remain largely elusive. Here we show that cardiac expression of vacuolar protein sorting 34 (Vps34) is reduced in a subset of HCM patients. In a mouse model, muscle-specific loss of Vps34 led to HCM-like manifestations and sudden death...

BACKGROUND: Optimal timing of implantation of an implantable cardioverter/defibrillator (ICD) after newly diagnosed heart failure is unclear given that late reverse remodelling may occur. We aimed to analyze left ventricular ejection fraction (LVEF) after diagnosis of an LVEF ≤35% during optimization of heart failure drug therapy. METHODS AND RESULTS: One hundred fifty-six patients with newly diagnosed LVEF ≤35% receiving a wearable cardioverter/defibrillator (WCD) were analyzed...

Pre-participation screening is vital to exclude inherited cardiac conditions which have the potential to cause sudden cardiac death in seemingly healthy athletes. Recent research has questioned traditional theories of load-induced, dichotomous cardiac adaptation. We therefore considered whether a "one-size-fits-all" approach to screening can account for inter-individual differences brought about by sporting discipline, training volume, ethnicity, body size, sex and age.

BACKGROUND: Asymmetric (ADMA) and symmetric dimethylarginine (SDMA) are putative uremic toxins that may exert toxicity by a number of mechanisms, including impaired nitric oxide synthesis and generation of reactive oxygen species. The study goal was to determine the association between these metabolites and cardiovascular outcomes in hemodialysis patients. STUDY DESIGN: Post hoc analysis of the Hemodialysis (HEMO) Study. SETTING & PARTICIPANTS: 1,276 prevalent hemodialysis patients with available samples 3 to 6 months after randomization...

A 10-year-old well and asymptomatic female was referred for screening of acute right ventricular dilatation (ARVD) as she had an elder brother diagnosed with ARVD whom died of sudden cardiac death. Electrocardiography (ECG), transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (CMR) were performed. Results of these investigations were suggestive of ARVD. Despite being a rare cardiac disease and largely unrecognised in children and young adult population, ARVD is an important cause of ventricular arrhythmias in this group of patients and is one of the causes of sudden cardiac death (SCD) in this population...

REVIEW
Josef Finsterer, Claudia Stöllberger, Jeffrey A Towbin
Left ventricular hypertrabeculation (LVHT) or noncompaction is a myocardial abnormality of unknown aetiology, frequently associated with monogenic disorders, particularly neuromuscular disorders, or with chromosomal defects. LVHT is diagnosed usually by echocardiography by the presence of a bilayered myocardium consisting of a thick, spongy, noncompacted endocardial layer and a thin, compacted, epicardial layer. The pathogenesis of LVHT is unsolved, and the diagnostic criteria, prognosis, and optimal treatment of patients with LVHT are under debate...

INTRODUCTION: Atrioventricular node (AVN) contusion usually results in cardiogenic shock and arrhythmia and is a rare but fatal condition. The condition is difficult to diagnose and easily overlooked because it develops rapidly and is asymptomatic. We here report 3 cases that demonstrate blunt chest impact and hemorrhages of the posterior atrioventricular junction, eventually result in death. CLINICAL FINDINGS: Autopsy and histological examination were performed on all cases...
