Recent studies demonstrated potential effects of stem cells on cardiac function in heart failure. However, influences of the technique of application remained undetermined. In the present study, the pericardial sac was used as depot for fluorescent-labeled mesenchymal stem cells in rats. To evaluate influences of inflammation on cell homing, a sterile pericarditis was induced by talc. It is shown that intrapericardial stem cells application is sufficient to provide myocardial penetration. The extent of homing was amplified by inflammation in a talc-induced pericarditis...

Drosophila imaginal disc growth factor 2 (IDGF2) is a member of chitinase-like protein family (CLPs) able to induce the proliferation of imaginal disc cells in vitro. In this study we characterized physiological concentrations and expression of IDGF2 in vivo as well as its impact on the viability and transcriptional profile of Drosophila cells in vitro. We show that IDGF2 is independent of insulin and protects cells from death caused by serum deprivation, toxicity of xenobiotics or high concentrations of extracellular adenosine (Ado) and deoxyadenosine (dAdo)...

INTRODUCTION: The heart and the kidneys are tightly interlinked with each other. So, primary disorder of one of these organs often results in the secondary dysfunction of other. Such interactions play a vital role in the pathogenesis of a clinical entity called cardio-renal syndrome (CRS). CRS type 4 refers to the development of cardiac failure in the patients with CKD. OBJECTIVES: To study the prevalence of various cardiac diseases in the patients with CKD and risk factors for it...

BACKGROUND: Pericoronary epicardial adipose tissue (cEAT) serves as a metabolic and paracrine organ that contributes to inflammation and is associated with macrovascular coronary artery disease (CAD) development. Although there is a strong correlation in humans between cEAT volume and CAD severity, there remains a paucity of experimental data demonstrating a causal link of cEAT to CAD. The current study tested the hypothesis that surgical resection of cEAT attenuates inflammation and CAD progression...

We report the case of a 74-year-old woman admitted to the emergency unit for resting dyspnea. Clinical presentation, cardiac MRI and echocardiography were consistent with cardiac tamponade requiring emergency pericardiocentesis. Cytologic examination of the pericardial fluid revealed the presence of CD68(pos) CD1a(neg) S100(neg) foamy histiocytes (Fig. 1). Additional investigations complied with the diagnosis of Erdheim-Chester histiocytosis. Treatment with αIFN was initiated but the patient developed severe neutropenia that contraindicated further administration...

Light-chain-related amyloidosis is a systemic disease characterized by continuous accumulation of insoluble fibrillar proteins in different organs. Cardiac involvement is frequent in this condition. However, atypical presentations and unusual amyloid deposits localization may be encountered making the diagnosis challenging. We present here a case of a light-chain-related pericardial amyloidosis without evidence of myocardial involvement and emphasize the difficulty and importance of amyloidosis typing before starting treatment...

We present the case of a type AB thymoma in a 69-year-old man with previous coronary artery bypass grafting (CABG) in whom angiography revealed a left internal mammary artery graft supplying blood flow to a thymic neoplasm, which simultaneously occluded the graft. This required a redo sternotomy, lysis of pericardial adhesions, complete thymectomy, and redo one vessel off-pump CABG. This case seeks to sensitize physicians to the possibility of coronary adverse events in patients with a previous CABG in the setting of management of mediastinal neoplasms, and it presents the novel findings on cardiac imaging associated with this case...

BACKGROUND: In patients with nonvalvular atrial fibrillation (NVAF), embolic stroke is thought to be associated with left atrial appendage (LAA) thrombi. The WATCHMAN LAA Occlusion Device has been shown to be noninferior to conventional oral anticoagulation with warfarin for stroke prevention in patients with NVAF. This study aimed to evaluate the procedural feasibility, safety and 12-month outcomes of the WATCHMAN LAA Occlusion Device in NVAF patients with high risk for stroke in China...

A 63-year-old man with a history of remote inferior myocardial infarction and coronary artery bypass grafting (CABG) underwent catheter ablation of ventricular tachycardia (VT). Epicardial catheter ablation of the VT was successful at the crux of the heart despite limited mapping within the pericardial space due to pericardial adhesion. Percutaneous subxiphoidal pericardial approach is usually impossible in patients with a history of open heart surgery due to pericardial adhesions. This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG...

PURPOSE: The aim of this study was to assess the performances of unenhanced post-mortem computed tomography (CT) to detect thoracic injuries in violent death. MATERIALS AND METHODS: Retrospectively, we conducted a review of unenhanced CT scans of 67 victims of violent deaths with thoracic injuries and compared CT findings with the results of clinical autopsy. Our gold standard was a comparison of CT scans with autopsy discussed in a monthly forensic radiology multidisciplinary team meeting (MDTM)...

REVIEW
Douglas R Johnston
Disease of the pericardium represents a relatively rare indication for cardiac surgery, and there exist no widely accepted guidelines for surgical management. As such, the surgical approach to the pericardium has relied largely on institutional experience with a slow evolution based on published studies. In particular, management of pericardial constriction has varied widely from surgeon to surgeon and institution to institution, in large part due to a perception of inherent high risk to the procedure. This review covers the current practice of surgery for disease of the pericardium, with particular focus on the evolution of indications for pericardiectomy, new applications in inflammatory or relapsing pericarditis, and the progressive refinement in surgical technique and operative planning which have led to significantly improved outcomes in experienced centers...

Constrictive pericarditis is characterized by thick pericardial fibrosis and frequent calcification that progressively impairs diastolic filling of the heart. The diagnosis of constrictive pericarditis has been challenging even though multiple diagnostic modalities have been developed. The diagnosis of constructive pericarditis is especially difficult in localized constrictive pericarditis which is extremely rare. We report a case of localized constrictive pericarditis with a 3D multislice cardiac computed tomography (CT) finding of the constrictive band causing strangulation and hourglass shaping of the right ventricle...

BACKGROUND: Acute dyspnea is a common symptom in the emergency department (ED). Standard approach to dyspnea often relies on radiologic and laboratoristic results, causing excessive delay before adequate therapy is started; an integrated point-of-care ultrasonography (PoCUS) approach can shorten the time needed to formulate a diagnosis maintaining an acceptable safety profile. METHODS: Consecutive adult patients presenting with dyspnea and admitted after ED evaluation were prospectively enrolled...

Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review...

BACKGROUND: Utidelone, a genetically engineered epothilone analogue, has shown promise as a potential treatment for breast cancer in phase 1 and 2 trials. The aim of this phase 3 trial was to compare the efficacy and safety of utidelone plus capecitabine versus capecitabine alone in patients with metastatic breast cancer. METHODS: We did a multicentre, open-label, superiority, phase 3, randomised controlled trial in 26 hospitals in China. Eligible participants were female patients with metastatic breast cancer refractory to anthracycline and taxane chemotherapy regimens...
