A 69 year old male, an ex-smoker, was admitted with ongoing chest pain of 11 hours duration. Past medical history included treated hypertension and gastro-oesophageal reflux disease. He delayed seeking medical attention as he assumed the pain to be due to indigestion and kept taking antacids without much symptomatic relief. Clinical examination on arrival was unremarkable. Admission 12 lead electrocardiogram (ECG) was diagnostic of a recent anterolateral myocardial infarction (MI) (Figure 1a). Bedside trans-thoracic echocardiogram (TTE) confirmed an established anterolateral MI (Video 1, Figure 1b)...

Takotsubo cardiomyopathy is characterized by apical ballooning of the left ventricle (LV) in the absence of relevant coronary artery stenosis, which typically occurs in elderly women after emotional stress. Catecholamine cardiotoxicity, metabolic disturbance, and coronary microvascular impairment have previously been proposed as underlying pathophysiologic mechanisms of takotsubo cardiomyopathy, whereas myocardial stunning resulting from epicardial coronary artery vasospasm is not generally accepted as a cause of takotsubo cardiomyopathy...

BACKGROUND: Takostsubo (stress) cardiomyopathy (TC) is a clinical syndrome featuring transient left ventricular dysfunction and wall-motion abnormalities, usually following emotional or physical stress. The diagnosis of TC depends on fulfillment of multiple clinical criteria. Although the pathogenesis has not been firmly established, myocardial cathecholamine toxicity is thought to represent a primary mechanism. The vast majority of patients with TC survive. However, a rare cause of death in TC is myocardial rupture...

BACKGROUND: Acute thoracic aortic dissections and ruptures, the main life-threatening complications of the corresponding aneurysms, are an important cause of sudden cardiac death. Despite the usefulness of the molecular diagnosis of these conditions in the clinical setting, the corresponding forensic field remains largely unexplored. The main goal of this study was to explore and validate a new massive parallel sequencing candidate gene​ assay as a diagnostic tool for acute thoracic aortic dissection autopsy cases...

Echinococcosis is a cosmopolitan zoonotic parasitic disease caused by infection with the larval stage of tapeworms from the Echinococcus genus, most commonly Echinococcus granulosus. According to WHO, more than 1 million people are affected by hydatid disease at any time.1 About 10% of the annual cases are not officially diagnosed.2 In humans, the disease is characterized by development of three-layered cysts. The cysts develop primarily in the liver and the lungs, but can also affect any other organ due to the spreading of the oncospheres...

Kounis syndrome is defined as the coincidental occurrence of an acute coronary syndrome with hypersensitivity reactions following an allergic event. The three reported variants of Kounis syndrome are vasospastic allergic angina, allergic myocardial infarction and stent thrombosis with occluding thrombus. The syndrome is caused by various inflammatory mediators. The pathophysiological characteristics of Kounis syndrome involve coronary artery spasm and/or atheromatous plaque erosion or rupture during an allergic reaction...

Primary cardiac and pericardial tumors are rare entities with an autopsy frequency of 0.001-0.03%. Metastases to the heart and pericardium are much more common than primary tumors. Malignant pericardial mesotheliomas account for up to 50% of primary pericardial tumors. We report the case of a 75-year-old woman with hypertension, dyslipidemia and atrial fibrillation who went to the emergency department due to nonspecific thoracic discomfort of over six hours duration associated with syncope. Physical examination revealed a low-amplitude arrhythmic pulse, no heart murmurs and no signs of pulmonary congestion...

A Ben Khalfallah, H Ben Slima
Cardiac echinococcosis is rare. Its spontaneous course is serious because of the risk of rupture. Its clinical manifestations are variable, often latent and misleading. The diagnosis is sometimes referred to by chest radiography. It is much facilitated by non-invasive imaging techniques in particular transesophageal and transthoracic echocardiography, CT scan and magnetic resonance imaging. The latter through a morphological and topographical analysis accurate diagnosis of hydatid cyst and its relationship to cardiac muscle and surrounding tissue...

Aims: Monocytes/macrophages response plays a key role in post-infarction inflammation that contributes greatly to post-infarction ventricular remodelling and cardiac rupture. Therapeutic targeting of the GABAA receptor, which is enriched in monocytes/macrophages but not expressed in the myocardium, may be possible after myocardial infarction (MI). Methods and results: After MI was induced by ligation of the coronary artery, C57BL/6 mice were intraperitoneally administered with one specific agonist or antagonist of the GABAA receptor (topiramate or bicuculline), in the setting of presence or depletion of monocytes/macrophages...

Cardiac pseudoaneurysm is a contained rupture of the myocardium limited by pericardial adhesions or the epicardial wall. Cardiac pseudoaneurysm may cause sudden death with a mortality of 30-45% in the first year, mostly resulting from rupture. Coronal and axial T2-weighted magnetic resonance images of a 65-year-old male patient admitted with dyspnoea, coughing and chest pain, present for the last 10 days, revealed a large pseudoaneursym of the left ventricle. Coronary bypass and left ventricular restoration operation was performed...

We describe the case of a 23-year-old white female, 10-12 weeks pregnant, with a history of intravenous drug use and a recently diagnosed pneumonia, who was found deceased in her bed after a night of sleep. Although postmortem serum toxicology tested positive for alprazolam, tetrahydrocannabinol, and morphine, the ultimate cause of death was determined to be cardiac tamponade secondary to an isolated abscess in the ascending aorta. The patient had several risk factors for aortic rupture and cardiac tamponade including intravenous drug use, pneumonia, and pregnancy...
