Blunt thoracic aortic injury (TAI) occurs most frequently as a sequelae of high impact deceleration such as high velocity road traffic accidents and falls from height. The burden of mortality and morbidity is high, however advances in pre-hospital care, diagnostic imaging and endovascular therapies have improved outcomes in this group of patients. Emergent treatment depends on accurate, early diagnosis by the radiologist. It is therefore of paramount importance that radiologists are familiar with both the direct (intimal flap, pseudoaneurysm, aortic contour irregularity and contrast extravasation) and indirect (periaortic haematoma) imaging findings of TAI...

Background: Right sided tears or rupture are the most common injury to the heart after blunt chest trauma. The majority of these injuries are to the thin walled atrium. Reports of localized right atrial appendage rupture are rare. The classical features of Beck's triad are unreliable in the trauma bay. With the advent of EFAST (Focused assessment with sonography for trauma extended to thorax), Beck's triad should be considered but not used as the primary clinical tool for diagnosis of cardiac tamponade [1]...

Blunt cardiac injury (BCI) with free wall rupture carries a high risk of pre-hospital death. Cardiopulmonary bypass (CPB) has been utilized as a bridge to repair of cardiac lesions in select patients. We present an interesting case of emergency department repair of right atrial rupture with cardiopulmonary bypass.

AIM: Previous studies have proved that activation of aldehyde dehydrogenase two (ALDH2) can attenuate oxidative stress through clearance of cytotoxic aldehydes, and can protect against cardiac, cerebral and lung ischemia/reperfusion (I/R) injuries. In this study, we investigated the effects of the ALDH2 activator Alda-1 on hepatic I/R injury. METHODS: Partial warm ischemia was performed in the left and middle hepatic lobes of Sprague-Dawley rats for 1 h, followed by 6 h of reperfusion...

Literature discussing cardiac injuries in children is limited. Systematic search of PubMed identified 21 studies enrolling 1,062 pediatric patients who experienced cardiac trauma in the United States during the period 1961 to 2012. The predominant type of injury was blunt cardiac contusion affecting 59.7% (n = 634/1,062) of the study population. Motor vehicle crashes (53.5%, n = 391/731) were the leading cause of blunt cardiac trauma, while gunshot wounds (50%, n = 150/300) accounted for most penetrating injuries...

The commonest cause of blunt cardiac injuries is from traffic accidents followed by violent falls, sport activities, accidents or a fight but rupture of the heart is rare and lethal. The precise incidence of cardiac injury after a blunt chest trauma is unknown as rates vary greatly in the literature from between 7% and 76% of cases. Autopsy studies have shown that the right ventricle is the most frequently ruptured, followed by the left ventricle, right atrium, intraventricular septum, left atrium and interatrial septum with decreasing frequency...

BACKGROUND: Viral myocarditis is a widespread cardiac disease associated with inflammation and myocardial injury and is predominantly caused by coxsackievirus B3 (CVB3) infection in humans as well as in mice. CVB3-induced myocarditis shows sexually dimorphic sensitivity and is more prevalent in male mice. Our previous studies showed that natural killer (NK) cells played an indispensable role in CVB3-induced myocarditis, and female mice exhibited less pathological cardiac interferon gamma (IFN-γ)+ NK cell infiltration than did male mice...

Oxidative stress and inflammation play key roles in the development of diabetic cardiomyopathy (DCM). Dimethyl fumarate (DMF), an FDA approved medicine for relapsing multiple sclerosis, has manifested its antioxidant and anti-inflammatory function mostly in the central nervous system. In this study, we investigated whether DMF could attenuate the development of DCM. Type 1 diabetes mouse model was established using multiple low-dose streptozotocin, and the diabetic mice were treated with DMF (10 mg/kg body weight) for 3 months...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is increasingly used as a noninvasive clamp of the aorta after diverse posttraumatic injuries. Balloon inflation in zone 3 (from the lower renal artery to the aortic bifurcation) can be performed to stop ongoing bleeding after severe pelvic trauma with life-threatening hemorrhage. The aim of our study was to describe our 20-year experience with REBOA in terms of efficacy and safety in patients with a suspicion of severe pelvic trauma and extreme hemorrhagic shock...

Background: Cytochrome c is an intermembrane mitochondrial protein that is released to the bloodstream following mitochondrial injury. Methods and results: We developed an electrochemiluminescence immunoassay to measure cytochrome c in human and rat plasma, which showed high sensitivity with broad dynamic range (2-1200 ng/mL in humans and 5-500 ng/mL in rat) and high assay reproducibility (inter-assay coefficient <6% in humans and <10% in rat). In patients after blunt trauma, plasma cytochrome c directly correlated with injury severity...

The purpose of this study was to define the relationship between cardiac depression and morphological and immunological alterations in cardiac tissue after multiple trauma. However, the mechanistic basis of depressed cardiac function after trauma is still elusive. In a porcine polytrauma model including blunt chest trauma, liver laceration, femur fracture and haemorrhage serial trans-thoracic echocardiography was performed and correlated with cellular cardiac injury as well as with the occurrence of extracellular histones in serum...

Myocardial contusion and aortic injury are well-known cardiac complications of blunt chest trauma, but valvular injury is rare. Traumatic valve injuries most commonly involve the aortic valve, with isolated mitral valve injury being quite rare. We report a case of acute severe mitral regurgitation due to ruptured chordae tendineae requiring surgical repair following a motor vehicle accident.

The incidence of blunt chest trauma (BCT) is greater than 15% of all trauma admissions to the emergency departments worldwide and is the second leading cause of death after head injury in motor vehicle accidents. The mortality due to BCT is inhomogeneously described ranging from 9% to 60%. BCT is commonly caused by a sudden high-speed deceleration trauma to the anterior chest, leading to a compression of the thorax. All thoracic structures might be injured as a result of the trauma. Complex cardiac arrhythmia, heart murmurs, hypotension, angina-like chest pain, respiratory insufficiency or distention of the jugular veins may indicate potential cardiac injury...
