Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides mechanical circulatory support for patients with advanced cardiogenic shock, facilitating myocardial recovery and limiting multi-organ failure. In patients with severely limited left ventricular ejection, peripheral VA-ECMO can further increase left ventricular and left atrial pressures (LAP). Failure to decompress the left heart under these circumstances can result in pulmonary edema and upper body hypoxemia, that is, myocardial and cerebral ischemia...

Objective: To observe the clinical efficacy and safety of coil embolization of septal branch in the treatment of obstructive hypertrophic cardiomyopathy (HOCM). Methods: Eighteen patients with HOCM hospitalized in our department from September 2014 to October 2016 were enrolled in this study. There were 12 males and 6 females in this cohort and the age of patients ranged from 22 to 64 years old. Left ventricular outflow tract gradient (LVOTG) was derived from echocardiographic apical five-chamber view at pre-operation and at 48 hours and 6 months post operation...

OBJECTIVE: To observe the effect of moxibustion (Moxi) preconditioning with seed-sized moxa cones on myocardial ischemia-reperfusion injury (MI/RI) at different stages, and to analyze the correlation between this effect and the expression of autophagy related protein Beclin 1. METHODS: This study contains two parts: 1) changes of myocardial pathological injury and percentages of myocardial infarcted area at different time-points after modeling and Moxi intervention, and 2) effect of Moxi on contents of serum cardiac troponin T(cTnT) and expression of myocardial Bcl-2, Bax and Beclin 1 proteins...

Wild ruminants, including deer species (cervids) have incorrectly been regarded as refractory to yew (Taxus) intoxication. This assumption has been based upon anecdotal observations of individual deer browsing on yew over time without apparent adverse effect. A single case of yew intoxication was reported in a free-ranging Norwegian moose (Alces alces) in 2008. The current report describes five additional cases of yew toxicosis in moose, seven in roe deer (Capreolus capreolus) and two in reindeer (Rangifer tarandus tarandus), all in Norway...

OBJECTIVES: Heart transplantation (HTX) in mice is used to characterize gene-deficient mice and to test new treatment strategies. The purpose was to establish noninvasive magnetic resonance imaging techniques in mice to monitor pathophysiological changes of the allograft during rejection. MATERIALS AND METHODS: Magnetic resonance imaging was performed at baseline and days 1 and 6 after isogenic (n = 10, C57BL/6) and allogenic (n = 12, C57BL/6 to BALB/c) heterotopic HTX on a 7 T small animal scanner...

BACKGROUND: Takotsubo cardiomyopathy is characterized by the basal hypercontractility and apical ballooning of the left ventriculum and T-wave inversion in the electrocardiogram. It has been suggested that Takotsubo cardiomyopathy might underlie the pathogenesis of persistent cardiac dysfunction; however, few reports are present demonstrating the advent of Takotsubo cardiomyopathy in patients with idiopathic cardiomyopathy. CASE PRESENTATION: A 64-year-old women was admitted due to dyspnea on effort and lower extremity edema...

The patient was a 32-year-old man with a previous history of bronchial asthma. He was admitted with chief complaints of dyspnea and skin rash associated with itching of the palms and soles of the feet, which began 2 weeks earlier. Because of the presence of cardiac failure and increase in the peripheral blood eosinophil count, eosinophilic myocarditis (EM) was suspected. His blood pressure gradually decreased and the patient went into cardiogenic shock. Therefore, endomyocardial biopsy was performed and was immediately followed by corticosteroid therapy and intra-aortic balloon pump (IABP) placement...

OBJECTIVES: To observe and analyze the performance of forensic science in the cases of suxa- methonium chloride poisoning, and to improve the identification of suxamethonium chloride poisoning. METHODS: Fifty-four cases of suxamethonium chloride poisoning were collected. The rules of determination of suxamethonium chloride poisoning were observed by the retrospective analysis of pathological and toxicological changes as well as case features. RESULTS: The pathological features of suxamethonium chloride poisoning were similar to the general changes of sudden death, which mainly included acute pulmonary congestion and edema, and partly showed myocardial disarray and fracture...

REVIEW
Dante A Suffredini, Xizhong Cui, Wanying Xu, Yan Li, Peter Q Eichacker
Shock with B. anthracis infection is particularly resistant to conventional cardiovascular support and its mortality rate appears higher than with more common bacterial pathogens. As opposed to many bacteria that lack exotoxins directly depressing hemodynamic function, lethal and edema toxin (LT and ET respectively) both cause shock and likely contribute to the high lethality rate with B. anthracis. Selective inhibition of the toxins is protective in infection models, and administration of either toxin alone in animals produces hypotension with accompanying organ injury and lethality...

OBJECTIVES: Perturbed hemodynamic function complicates severe malaria. The Fluid Expansion as Supportive Therapy trial demonstrated that fluid resuscitation, involving children with severe malaria, was associated with increased mortality, primarily due to cardiovascular collapse, suggesting that myocardial dysfunction may have a role. The aim of this study was to characterize cardiac function in children with severe malaria. DESIGN: A prospective observational study with clinical, laboratory, and echocardiographic data collected at presentation (T0) and 24 hours (T1) in children with severe malaria...

Background: Diabetic patients may be more susceptible to myocardial injury after coronary interventions. Thus, the aim of this study was to assess the release of cardiac biomarkers, CK-MB and troponin, and the findings of new late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) in patients with type 2 diabetes mellitus after elective revascularization procedures for multivessel coronary artery disease (CAD). Methods: Patients with multivessel CAD and preserved systolic ventricular function underwent either elective percutaneous coronary intervention (PCI), off-pump or on-pump bypass surgery (CABG)...

Organophosphorus (OP) pesticide poisoning is a major clinical and public health problem in a developing country like India. Cardiac injury is a strong predictor of death in these patients. Cardiac complications usually described include cardiac arrest, pulmonary edema, and arrhythmia. Rarely, myocardial infarction has also been reported. The possible mechanisms for myocardial injury include sympathetic/parasympathetic overactivity, hypoxemia, acidosis, dyselectrolytemia, and direct cardiotoxicity. We describe herein one case of OP poisoning, recently admitted in our emergency department and which was complicated by acute onset atrial fibrillation which reverted to sinus rhythm following detoxification of OP compound...

Adrenergic myocarditis is an uncommon presentation of pheochromocytoma and extremely rare cause of de novo acute heart failure (AHF). We present a case of a 31-year-old Caucasian woman with a history of hypertension and recurrent occipital headaches who was admitted to the emergency department due to severe de novo AHF presenting as pulmonary edema and cardiogenic shock. During the hospital admission the patient experienced asystolic cardiac arrest and was successfully resuscitated, intubated, and mechanically ventilated...

BACKGROUND: Early risk stratification after primary percutaneous coronary intervention (PPCI) for ST-segment-elevation myocardial infarction is currently challenging. Identification of a low-risk group may improve triage of patients to alternative clinical pathways and support early hospital discharge. Our aim was to assess whether the index of microcirculatory resistance (IMR) at the time of PPCI can identify patients at low risk of early major cardiac complications and to compare its performance against guideline-recommended risk scores...
