Cardiac tamponade results from compression of the heart and great vessels. Mediastinal hematoma has been reported in association with cardiac tamponade in multiple settings, including nonaortic mediastinal hemorrhage from cervical spine fractures, aortic and carotid aneurysmal rupture, mediastinal penetrating trauma, and cardiac penetrating trauma. A few cases of blunt trauma to the anterior chest wall resulting in tamponade formation have been reported. We present a patient with an anterior mediastinal hematoma resulting from blunt chest trauma that caused extrapericardial cardiac tamponade due to bleeding from a branch of the left internal mammary artery after a motor vehicle collision.

INTRODUCTION
Non-typhoidal Salmonella (NTS) is mostly restricted to gastroenteritis; however, we report a case of Salmonella pericarditis complicated by tamponade and spontaneous ventricular wall rupture.
CASE PRESENTATION
A 67-year-old male presents to the Emergency Department with complaints of fevers, chills and body aches. A chest radiograph displayed an infiltrate and an electrocardiogram suggested acute pericarditis. An echocardiogram revealed a small pericardial effusion without tamponade. Broad-spectrum antibiotics were initiated until Salmonella was discovered in blood cultures. The hospital course was complicated by sudden decompensation, and a repeat echocardiogram displayed a large effusion with constrictive physiology. During a pericardial window, the tissue was noted to have a thickened appearance with a complex effusion. The following day, the patient developed increased chest tube drainage, hypotension and acidosis, requiring an emergent sternotomy. The right ventricle was friable and had spontaneously ruptured. After ventricular repair and pericardiectomy, the tissue was sent for cultures and pathology. The specimen revealed Salmonella enteriditis. Treatment with ceftriaxone and ciprofloxacin was initiated. On postoperative day four, the patient was successfully extubated. Repeat blood cultures were negative.
DISCUSSION
In our review of literature, only 19 cases of NTS pericarditis have been reported. Prior to our case, salmonellosis resulting in ventricular rupture has been reported once. Early diagnosis and treatment is crucial in minimizing morbidity and mortality. Clinical suspicion based on electrocardiogram and hemodynamic assessment is critical in suspecting pericardial effusion in a patient with nonspecific symptoms and Salmonella bacteremia. The key to recovery involves aggressive treatment, including pericardiectomy and antibiotic treatment.

The changes in cardiac function that occur after pericardiocentesis are unclear. An understanding of the effect of pericardiocentesis on right ventricular (RV) and left ventricular (LV) function is clinically important. This study was performed to assess RV and LV function with echocardiography before and after pericardiocentesis. In total, 19 consecutive patients who underwent pericardiocentesis for more than moderate pericardial effusion were prospectively enrolled from August 2015 to October 2017. Comprehensive transthoracic echocardiography was performed before, immediately after (within 3 h), and 1 day after pericardiocentesis to investigate the changes in RV and LV function. The mean age of all patients was 72.6 ± 12.2 years. No pericardiocentesis-related complications occurred during the procedure, but one patient died of right heart failure 8 h after pericardiocentesis. After pericardiocentesis, RV inflow and outflow diameters increased (p < 0.05 versus values before pericardiocentesis), and the parameters of RV function (tricuspid annular plane systolic excursion, tricuspid lateral annular systolic velocity, fractional area change, and RV free wall longitudinal strain) significantly decreased (p < 0.001 versus values before pericardiocentesis). These abnormal values or RV dysfunction remained 1 day after pericardiocentesis (p > 0.05 versus values immediately after pericardiocentesis). Conversely, no parameters of LV function changed after pericardiocentesis. Of 19 patients, 13 patients showed RV dysfunction immediately after pericardiocentesis and 6 patients did not. RV free wall longitudinal strain before pericardiocentesis in patients with post-procedural RV dysfunction was reduced compared to those without post-procedural RV dysfunction ( - 18.9 ± 3.6 versus - 28.4 ± 6.3%; p = 0.005). The area under the curve values for prediction of post-procedural RV dysfunction was 0.910 for RV free wall longitudinal strain. The occurrence of RV dysfunction after pericardiocentesis should be given more attention, and pre-procedural RV free wall longitudinal strain may be a predictor of post-procedural RV dysfunction.

Review
The arrhythmogenic substrate in patients with Chagas cardiomyopathy, arrhythmogenic dysplasia, postmyocarditis nonischemic dilative cardiomyopathy as well as after extensive posterior or anterior wall myocardial infarction is predominantly located epicardially. This can necessitate epicardial access for an effective, substrate-based catheter ablation of the ventricular tachycardia (VT). Anterior percutaneous epicardial puncture represents the standard approach for epicardial VT ablation. The most important anatomical particularities that must be taken into account when performing an epicardial puncture or epicardial VT ablation are epicardial coronary arteries, left phrenic nerve and epicardial fat. The typical anatomic characteristics of the epicardial structures and resulting considerations for epicardial access are discussed here in detail.

An efficient animal model is fundamental for studies on the underlying mechanisms of constrictive pericarditis (CP). A novel CP rat model was established by pericardial injection composing of lipopolysaccharides (LPS) and talcum powder without thoracotomy. Pathological changes were confirmed by histological staining. E-flow Doppler of mitral valve, tissue Doppler E' in the medial mitral annular (E' ) and the lateral mitral annular (E' ) were measured to assess ventricular filling function. Circumferential, longitudinal, and radial strains (SC, SL and SR) and the respective strain rates (SrC, SrL and SrR) were analyzed in interventricular septum (IVS) and left ventricular free wall (LVFW). Rat cardiac fibroblasts (CFs) were treated with LPS. The activation of transforming growth factor β1 (TGF-β1) was confirmed by Q-PCR and western blot assays. Thickening of pericardium and fibrosis in pericardium and subepicardial myocardium were showed in the model group. Diastolic dysfunction in the CP group was indicated by decreased E' and E' /E' , increased E/E' , decreased E of SrC and SrL, increased A and decreased E/A of SrC, SrL and SrR. Systolic dysfunction was indicated by decreased SC and SL in CP rats. The levels of TGF-β1, p-Smad2/3, α-smooth muscle actin (α-SMA), and collagen-I/III (COL-I/III) were increased in the CP group. The increased TGF-β1 that induced by LPS activated and phosphorylated Smad2/3 resulting in the secretion of α-SMA and COL-I/III. This model is of vital importance in studying the pathogenesis of CP.

Review
Inflammation plays a crucial role in the development and destabilization of atherosclerotic plaques in coronary vessels. Adipose tissue is considered to act in paracrine manner, which modulates a number of physiological and pathophysiological processes. Perivascular adipose tissue has developed specific properties that distinguish it from the fat in other locations. Interestingly, its activity depends on several metabolic conditions associated with insulin resistance and weight gain. Particularly in obesity perivascular fat seems to change its character from a protective to a detrimental one. The present review analyzes literature in terms of the pathophysiology of atherosclerosis, with particular emphasis on inflammatory processes. Additionally, the authors summarize data about confirmed paracrine activity of visceral adipose tissue and especially about pericoronary fat influence on the vascular wall. The contribution of adiponectin, leptin and resistin is addressed. Experimental and clinical data supporting the thesis of outside-to-inside signaling in the pericoronary milieu are further outlined. Clinical implications of epicardial and pericoronary adipose tissue activity are also evaluated. The role of pericoronary adipose tissue in obesity-related atherosclerosis is highlighted. In conclusion, the authors discuss potential therapeutical implications of these novel phenomena, including adipokine imbalance in pericoronary adipose tissue in the setting of obesity, the influence of lifestyle and diet modification, pharmaceutical interventions and the growing role of microRNAs in adipogenesis, insulin resistance and obesity. Key teaching points: • adipose tissue as a source of inflammatory mediators • changes in the vascular wall as a result of outside-to-inside signaling • anatomy, physiology, and clinical implications of epicardial and pericoronary adipose tissue activity • adipokines and their role in obesity-related atherosclerosis • therapeutic perspectives and future directions.

BACKGROUND
Mulibrey nanism (MUL) is a rare condition with profound growth delay. Congestive heart failure is a major determinant of prognosis. The aim was to delineate pericardial constriction and myocardial functional abnormalities in a pediatric MUL sample.
METHODS
A total of 23 MUL patients and 23 individually sex- and age-matched healthy control subjects were prospectively assessed in a cross-sectional study with echocardiography.
RESULTS
Clinical signs of heart failure were present in 7 MUL patients, with severe congestive heart failure in 2. Significant diastolic dysfunction, mainly related to constriction, was found in MUL patients without pericardiectomy (N = 18)-septal bounce, pronounced hepatic vein atrial reversal and right heart inflow-outflow variations, and decreased inferior vena cava collapse during respiration. The appearance of the pericardium was not different from that of control subjects. Longitudinal diastolic myocardial velocities were similar to those in control subjects, suggesting an absence of significant myocardial restriction. Right ventricular free wall longitudinal systolic strain and bilateral longitudinal myocardial systolic velocities were decreased in MUL patients, indicating mild biventricular systolic dysfunction. Myocardial motion abnormalities and persistent congestive heart failure were common (in 3 of 6) in MUL patients with a history of pericardiectomy. Cardiac dimensions were similar between MUL patients and control subjects when adjusting for body size, except for smaller biventricular volumes.
CONCLUSIONS
MUL disease presents with significant constriction-related diastolic dysfunction and mild bilateral systolic dysfunction. Constriction-restriction assessments during follow-up could be of benefit in decision-making regarding pericardiectomy in MUL disease. Myocardial abnormalities were prevalent among MUL patients who had undergone pericardiectomy and are consistent with progression of myocardial disease in a significant proportion of patients.

COPD often coexists with HFpEF, but its impact on cardiovascular structure and function in HFpEF is incompletely understood. We aimed to compare cardiovascular phenotypes in patients with Chronic Obstructive Pulmonary Disease (COPD), Heart Failure with Preserved Ejection Fraction (HFpEF), or both. We studied 159 subjects with COPD alone (n = 48), HFpEF alone (n = 79) and HFpEF + COPD (n = 32). We used MRI and arterial tonometry to assess cardiac structure and function, thoracic aortic stiffness, and measures of body composition. Relative to participants with COPD only, those with HFpEF with or without COPD exhibited a greater prevalence of female sex and obesity, whereas those with HFpEF + COPD were more often African-American. Compared to the other groups, participants with HFpEF and COPD demonstrated a more concentric LV geometry (LV wall-cavity ratio 1.2, 95%CI: 1.1-1.3; p = 0.003), a greater LV mass (67.4, 95%CI: 60.7-74.2; p = 0.03, and LV extracellular volume (49.4, 95%CI: 40.9-57.9; p = 0.002). Patients with comorbid HFpEF + COPD also exhibited greater thoracic aortic stiffness assessed by pulse-wave velocity (11.3, 95% CI: 8.7-14.0 m/s; p = 0.004) and pulsatile load imposed by the ascending aorta as measured by aortic characteristic impedance (139 dsc; 95%CI=111-166; p = 0.005). Participants with HFpEF, with or without COPD, exhibited greater abdominal and pericardial fat, without difference in thoracic skeletal muscle size. In conclusion, individuals with co-morbid HFpEF and COPD have a greater degree of systemic large artery stiffening, LV remodeling, and LV fibrosis than those with either condition alone.

Epithelial cardiac progenitor cells of the second heart field (SHF) contribute to growth of the vertebrate heart tube by progressive addition of cells from the dorsal pericardial wall to the cardiac poles. Perturbation of SHF development, including defects in apicobasal or planar polarity, results in shortening of the heart tube and a spectrum of congenital heart defects. Here, we provide detailed protocols for fixed section and wholemount immunofluorescence and live imaging approaches to studying the epithelial properties of cardiac progenitors in the dorsal pericardial wall during mouse heart development. Whole-embryo culture and electroporation methods are also presented, allowing for pharmacological and genetic perturbation of SHF development, as well as image analysis approaches to quantify cell features across the progenitor cell epithelium. These protocols are broadly applicable to the study of epithelia in the early embryo.

A 30-year-old man presented with swelling in the lower left ear. Close examination led to a diagnosis of parotid gland cancer, T4N0M0 Stage IVA, so total resection of the left parotid gland and left neck dissection were performed. Pathological examination led to a diagnosis of high-grade malignant-type mucoepidermoid, and chemoradiotherapy was performed as postoperative treatment. Fourteen days after completion of chemoradiotherapy, the patient was admitted to the hospital with headache and lack of appetite. Echocardiography showed a pericardial effusion and complete collapse of the right ventricle; cardiac tamponade was diagnosed, and pericardiocentesis was performed. The pericardial effusion was bloody, and a metastatic lesion was suspected, but cytological examination showed class IIIa. On day 33 of the illness, respiratory distress and hypotension were observed. A clot was seen covering the lower wall of the heart, and dilatation of the lower wall was significantly impaired. Pericardiotomy was performed on day 36. Pathological examination diagnosed cardiac metastasis of mucoepidermoid carcinoma of the parotid gland. Although only 4 cases of parotid cancer have been reported as primary lesions of metastatic heart tumors, this case represents the world's first description of isolated parenchymal metastasis of mucoepidermoid carcinoma of the parotid gland diagnosed by pericardial biopsy.
