As the conventional histopathologic examination of thymic carcinoma (TC) is nonspecific, immunohistochemical studies along with correlative radiographic investigations are needed for its correct diagnosis. TC commonly occurs in the late 5th to early 6th decades of life but is extremely rare in childhood. It may be incidentally detected from chest radiographs taken as routine or for other reasons. However, most patients present with symptoms such as chest pain, cough, shortness of breath, dysphagia and hoarseness, which are directly attributable to the mediastinal mass...

Cardiac troponin T (cTnT) serves as a structural protein of myocardial fiber, and participates in heart excitation-contraction coupling process. Here, we generated tnnt2a (cTnT-coding gene) deletion mutant zebrafish via CRISPR/Cas9 technique, and performed phenotypic analysis of the identified tnnt2a mutants. We observed that there was no significant difference between heterozygous mutant and wild type zebrafish, and the homozygous mutants displayed significant malformations in heart, including cardiac arrest, atrium and ventricle enlargement, pericardium effusion, and the individuals usually died before 7 day post fertilization (dpf)...

A 28-year-old Filipino male was admitted due to high-grade fevers and dyspnea on a background of chronic cough and weight loss. Due to clinical and echocardiographic signs of cardiac tamponade, emergency pericardiocentesis was performed on his first hospital day. Five days after, chest radiographs showed new pockets of radiolucency within the cardiac shadow, indicative of pneumopericardium. On repeat echo, air microbubbles admixed with loculated effusion were visualized in the anterior pericardial space. Constrictive physiology was also supported by a thickened pericardium, septal bounce, exaggerated respiratory variation in AV valve inflow, and IVC plethora...

Intrathoracic fat volume, more specifically, epicardial fat volume, is an emerging imaging biomarker of adverse cardiovascular events. The purpose of this work is to show the feasibility and reproducibility of intrathoracic fat volume measurement applied to contrast-enhanced multidetector computed tomography images. A retrospective cohort study of 62 subjects free of cardiovascular disease (55% females, age = 49 ± 11 years) conducted from 2008 to 2011 formed the study group. Intrathoracic fat volume was defined as all fat voxels measuring -50 to -250 Hounsfield Unit within the intrathoracic cavity from the level of the pulmonary artery bifurcation to the heart apex...

Penetrating thoracic injuries are rare in Germany and common in urban regions. 10 percent of the patients in Emergency Departments suffer from blunt thoracic trauma. Mechanism of trauma can predict the severity of the injuries. Very fast life-threatening injuries with hemodynamic problems like tension pneumothorax or cardiac tamponade have to be diagnosed. Prehospital emergency physicians need skills in ultrasound for diagnosis and in invasive therapy like chest tube or pericardium drainage tube. The application of an algorithm in exploration of a thoracic trauma seems to be useful...

Inferior vena caval (IVC) filters are used as a mechanical option for the treatment of venous thromboembolism (VTE) when standard anticoagulation therapy is either contraindicated or VTE recurs despite adequate anticoagulation. Filters are not without risk, however. Reported complications include filter migration and fracture of filter components, leading to IVC rupture and penetration into pericaval tissues (notably kidney, heart, pericardium, thoracic cavity, liver, bowel and aorta). Here we describe an extreme case of multiple organ penetration by a standard Celect caval filter...

Echocardiography revealed 2 aneurysms in the mitral valve with mitral regurgitation and aortic regurgitation,in a 42-years-old man. He had had infective endocarditis due to Streptococcus 9 months before. A prolapse in the right coronary cusp without vegetation and 2 aneurysms in the anterior mitral leaflet were found intraoperatively. Aortic valve was replaced, and then mitral aneurysms were resected and repaired using his own pericardium. There has been almost no regurgitation or recurrence of infection over 3 years...

A 6-year-old boy (weight 15.5 kg) underwent pulmonary valve plasty using autologous pericardium. He received a diagnosis of aortic coarctation and ventricular septal defect. Total correction was performed at the age of 18 days ( weight 2.2 kg). Intraoperatively, to confirm the position of the ventricular septum defect, we needed to incise from the main pulmonary artery to right ventricle through a commissure part of pulmonary valve. Although he exhibited stable hemodynamics, pulmonary valve regurgitation progressed...

BACKGROUND Sutureless aortic valves were introduced to facilitate minimally invasive aortic valve surgery. Since sutureless aortic valves are a feasible procedure, we evaluated if any benefits could be identified in severe high-risk patients with active infective endocarditis of the aortic valve. MATERIAL AND METHODS Between April 2014 and April 2015, a total of 42 patients received a sutureless Perceval® aortic valve (Sorin Biomedica Cardio Srl, Saluggia, Italy) for different indications. Nine of these patients (median age 71 years, range 47-83 years) suffered from active infective endocarditis, including four patients with prosthetic aortic valve endocarditis...

High level, acute exposures to individual polycyclic aromatic hydrocarbons (PAHs) and complex PAH mixtures result in cardiac abnormalities in developing fish embryos. While acute PAH exposures can be developmentally lethal, little is known about the later life consequences of early life, lower level PAH exposures in survivors. A population of PAH-adapted Fundulus heteroclitus from the PAH-contaminated Superfund site, Atlantic Wood Industries (AW), Elizabeth River, Portsmouth, VA, USA is highly resistant to acute PAH cardiac teratogenicity...

PURPOSE: The details of the mediastinal fascia have been scarcely described and the bronchopericardial membrane is the only known structure that is present between the bronchi and the pericardium. However, the anatomical description of this structure is unclear. This study aimed to investigate the fascial structures between the bronchi and the pericardium based on surgical findings. METHODS: The connective tissues in the mid-mediastinum were observed surgically when lung lobectomy, including mediastinal lymph node dissection for lung cancer, was performed at our institute from April 2011 to March 2016...

INTRODUCTION: Considering that the number of malignant diseases in patients over 65 years of age is increasing, it often occurs that patients who carry a cardiac implanted electronic device must undergo radiotherapy. Ionizing radiation can disturb the function of the implantable cardioverter-defibrillator (ICD). As a result of this, an update of the DEGRO/DKG guidelines for radiotherapy of this patient group has been published. METHODS: We report the case of a patient with an ICD and T‑lymphoblastic lymphoma with cardiac involvement, who received i...

The aim of this paper is to report an exceptional case of multiple internal exostoses of the ribs in a young patient affected by multiple hereditary exostoses (MHE) coming to our observation for chest pain as the only symptom of an intra-thoracic localization. A 16 years old patient with familiar history of MHE came to our observation complaining a left-sided chest pain. This pain had increased in the last months with no correlation to a traumatic event. The computed tomography (CT) scan revealed the presence of three exostoses located on the left third, fourth and sixth ribs, all protruding into the thoracic cavity, directly in contact with visceral pleura...

We introduce assistive techniques for proximal anastomosis in off-pump minimally invasive coronary artery bypass grafting (MICS CABG) to overcome difficult access to the ascending aorta in MICS CABG. An 8-cm left thoracotomy is made in the fifth intercostal space. ThoraTrak retractor (Medtronic Inc, Minneapolis, MN USA) is used to open the thoracotomy and is pulled to the cephalad and rightward direction toward to the ascending aorta. The pericardium is opened from the ascending aorta to the left ventricular apex and to the inferior vena cava...

Malignant pleural mesothelioma (MPM) is a tumor of mesodermal origin that arises from the serosa of the pleura, peritoneum, pericardium or tunica vaginalis. MPM is well known to have a poor prognosis with a median survival time of 12 months. Accurate diagnosis, staging and restaging of MPM are crucial with [18F] flurodeoxy-D-glucose positron emission tomography (FDG PET/CT) playing an increasingly important role. Here we report a case of MPM with unusual contiguous soft tissue spread of the tumor along the dermal and fascial planes characterized by PET/CT...
