Structural alterations in the cirrhotic heart may contribute to electromechanical abnormalities, represented by QT prolongation. The aim of this study was to investigate the changes in QTc according to the operative stage during pediatric LT and to identify which baseline echocardiographic parameters were associated with intraoperative QTc prolongation. Data were evaluated from 39 children undergoing LT for chronic liver disease (median age 9 months). In 19 patients (48.7%), baseline QTc was prolonged ≥440 ms (462 ± 19 ms)...

Speckle tracking echocardiography (STE) is increasingly used during functional assessments. However, reproducibility and dependence on echocardiographic image quality for speckle tracking stress echocardiography in pediatric patients have not been studied to date. 127 consecutive normotensive children without structural heart disease (mean age 13.4 ± 3.0 years, 50.4% female) underwent a stepwise semisupine cycle ergometric protocol. Left ventricular (LV) myocardial peak strain and strain rate were assessed at rest and during exercise...

Transient loss of consciousness represents one of the most frequent reasons for patients to present in the emergency room. Already at the very beginning, the diagnostic work-up is faced with fundamental questions: (1) Was it really a loss of consciousness? (2) Which department (neurology, cardiology, or others) should check the patient? (3) Is an in-hospital diagnostic work-up required? These questions can be answered from a meticulous patient history which needs to be adjusted to the individual case but also has to systematically go through a list of questions...

Transforming growth factor β1 (TGF-β1) and salvianolic acid B (Sal-B) are key signaling factors for stem cell differentiation into cardiomyocytes (CMs). The present study compared the biological effect of TGF-β1 and Sal-B, alone or in combination, on bone marrow mesenchymal stromal cells (BMSCs) that differentiate into myocardial-like cells in a simulated myocardial microenvironment in vitro . BMSCs were isolated from bones of limbs of 10 male Sprague Dawley rats and cultured. The 2nd-generation BMSCs were co-incubated with TGF-β1 and Sal-B, alone or in combination, for 72 h...

BACKGROUND: Previously proposed algorithms to predict the ventricular tachycardia (VT) exit site have been based on diverse left ventricle (LV) models, but none of them identify the precise region of origin on electroanatomical mapping (EAM). Moreover, no ECG algorithm has been tested to predict the region of origin of scar-related VTs in non-ischemic patients. OBJECTIVE: To validate a simple electrocardiographic algorithm to identify the segment of origin (SgO) VT relative to the 17-segment American Heart Association (AHA) model in patients with structural heart disease (SHD)...

Aortopulmonary window (APW) is rare a congenital heart disease accounting for 0.1%-0.2% of all congenital heart defects. The 35% of the APW has been associated with wide variety of other structural heart diseases such as ventricular septal defect, persistent ductus arteriosus, arch anomalies and coronary artery anomalies. To the best of our knowledge, only six cases of APW with pulmonary atresia with ventricular septal defect has been described in the literature. It resembles the type 1 truncus arteriosus, and differentiation from this condition is important prior to surgical correction...

Friedreich's ataxia (FA) is caused by reduced levels of frataxin, a highly conserved mitochondrial protein. There is currently no effective treatment for this disease, characterized by progressive neurodegeneration and cardiomyopathy, the latter being the most common cause of death in patients. We previously developed a Drosophila melanogaster cardiac model of FA, in which the fly frataxin is inactivated specifically in the heart, leading to heart dilatation and impaired systolic function. Methylene Blue (MB) was highly efficient to prevent these cardiac dysfunctions...

Background: Outflow tract (OFT) septation defects are a common cause of congenital heart disease. Numerous studies have focused on the septation mechanism of the OFT, but have reported inconsistent conclusions. This study, therefore, aimed to investigate the septation of the aortic sac and the OFT in the early embryonic human heart. Methods: Serial sections of 27 human embryonic hearts from Carnegie stage (CS) 10 to CS19 were immunohistochemically stained with antibodies against α-smooth muscle actin (α-SMA) and myosin heavy chain...

Severe tricuspid regurgitation (TR) is a complex condition of the right ventricle (RV) and tricuspid valve apparatus and is frequently associated with symptomatic heart failure and a significant morbidity and mortality. In these patients, left heart pathologies lead to chronic pressure overload of the RV, eventually causing progressive RV dilatation and functional TR. Therefore, TR cannot be considered as isolated heart valve disease pathology but has to be understood and treated as one component of a complex structural RV pathology and is frequently also a marker of an advanced stage of cardiac disease...

Although the strongly causal associations were between fine particulate matter (PM2.5 ) and cardiovascular disease, the toxic effect and potential mechanism of PM2.5 on heart was poorly understood. Thus, the aim of this study was to evaluate the cardiac toxicity of PM2.5 exposure on human cardiomyocytes (AC16). The cell viability was decreased while the LDH release was increased in a dose-dependent way after AC16 exposed to PM2.5 . The reactive oxygen species (ROS) generation and production of malondialdehyde (MDA) were increased followed by the decreasing in superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px)...

The lysosomal cysteine protease Cathepsin K is elevated in humans and animal models of heart failure. Our recent studies show that whole-body deletion of Cathepsin K protects mice against cardiac dysfunction. Whether this is attributable to a direct effect on cardiomyocytes or is a consequence of the global metabolic alterations associated with Cathepsin K deletion is unknown. To determine the role of Cathepsin K in cardiomyocytes, we developed a cardiomyocyte-specific Cathepsin K-deficient mouse model and tested the hypothesis that ablation of Cathepsin K in cardiomyocytes would ameliorate the cardiotoxic side-effects of the anticancer drug doxorubicin...
