Abstract Background: Bidirectional Glenn shunts have long been available as palliative procedures for patients with single ventricle physiology that is, patients unsuitable for biventricular repair. In our country they are performed at an older age than that recommended by the literature. So, we aim to assess post bidirectional Glenn shunt patients to detect the presence of any complications and to evaluate their functional capacity. Methods: This was a descriptive study that included all patients who underwent a bidirectional Glenn shunt and were referred for follow up in Ain shams university hospitals. History taking including NYHA class and physical activity, clinical examination,… More >

Abstract We report a very rare case of successful intracardiac correction in a patient with heterotaxy syndrome. The cardiac malformations included dextrocardia, double outlet right ventricle, pulmonary stenosis, interrupted inferior vena cava, hemiazygos continuation and total anomalous pulmonary venous return. One-stage correction was performed. The atrial procedure consisted of intra- and extraatrial rerouting of the anomalous systemic and pulmonary venous return. The hepatic veins were detached and diverted to the left atrium via an extracardiac conduit. The correction of the double outlet right ventricle was accomplished by intraventricular redirection of the blood flow from the left ventricle to the aorta. The… More >

Abstract Arterial switch operation (ASO) is a complex neonatal operation in which transfer of the coronary arteries origins is the key to success. Coronary events after a successful ASO are not uncommon. We describe a rare case of a child who underwent an ASO in the neonatal period with one coronary (LAD) described as atretic left in place. At age seven, he developed myocardial ischemia due to retrograde flow with a steal phenomenon from the LAD into the pulmonary artery. The patient underwent a late LAD reimplantation. This case underscores that even very small ostia should be translocated at the time… More >

Abstract Background: Left atrial appendage closure (LAAC) with simultaneous interventional occlusion therapy for congenital interatrial communication has become a new focus of patients with nonvalvular atrial fibrillation. Little is known about the results of mid-and long-term results. Objective: The aim of this study was to evaluate the midand long-term safety and effectiveness of simultaneous transcatheter closure of the left atrial appendage (LAA) and congenital interatrial communication closure in atrial fibrillation (AF) patients. Methods: From Jan 2016 to June 2017, 27 patients with AF were treated with simultaneous transcatheter closure of the LAA and atrial septal defect (ASD, n = 22), patent… More >

Abstract The aim of this study was to perform a systematic review and meta-analysis to evaluate the safety and efficacy of ductus arteriosus stent (DAS) compared with surgical systemic-pulmonary artery shunt (SPS) in patients with ductal-dependent pulmonary blood flow. A literature search was conducted in PubMed, Embase, and the Cochrane Library databases from their inception to December 2020. Two reviewers independently screened the articles, evaluated the quality of the articles, and collected the data. Meta-analyses were conducted using fixed and random effects models. We used the I-square (I² ) test to examine heterogeneity and the funnel plot Egger’s test was used… More >

Abstract Objectives: This study aimed to study the characteristics of in-hospital deterioration in patients with congenital heart disease who required rapid response system activation and identify risk factors associated with 1-month mortality. Methods: We retrospectively analysed data from a Japanese rapid response system registry with 35 participating hospitals. We included consecutive patients with congenital heart disease who required rapid response system activation between January 2014 and March 2018. Logistic regression analyses were performed to examine the associations between 1-month mortality and other patient-specific variables. Results: Among 9,607 patients for whom the rapid response system was activated, only 82 (0.9%) had congenital… More >

Abstract The high potentiality of integrating renewable energies, such as photovoltaic, into a modern electrical microgrid system, using DC-to-DC converters, raises some issues associated with controller loop design and system stability. The generalized state space average model (GSSAM) concept was consequently introduced to design a DC-to-DC converter controller in order to evaluate DC-to-DC converter performance and to conduct stability studies. This paper presents a GSSAM for parallel DC-to-DC converters, namely: buck, boost, and buck-boost converters. The rationale of this study is that modern electrical systems, such as DC networks, hybrid microgrids, and electric ships, are formed by parallel DC-to-DC converters with… More >

Abstract Internet of things enables every real world objects to be seamlessly integrated with traditional internet. Heterogeneous objects of real world are enhanced with capability to communicate, computing capabilities and standards to interoperate with existing network and these entities are resource constrained and vulnerable to various security attacks. Huge number of research works are being carried out to analyze various possible attacks and to propose standards for securing communication between devices in internet of things (IoT). In this article, a robust and lightweight authentication scheme for mutual authentication between client and server using constrained application protocol is proposed. Internet of things… More >

Abstract Security has always been a vital research topic since the birth of web application. A great deal of research has been conducted to determine the ways of identifying and classifying security issues or goals However, in the recent years, it has been noticed that high secure web applications have less durability; thus reducing their business continuity. High security features of a web application are worthless unless they provide effective services to the user and meet the standards of commercial viability. Hence, there is a need to bridge the gap between security and durability of the web application. Indeed, security mechanisms… More >

Abstract

In today’s world of connectivity there is a huge amount of data than we could imagine. The number of network users are increasing day by day and there are large number of social networks which keeps the users connected all the time. These social networks give the complete independence to the user to post the data either political, commercial or entertainment value. Some data may be sensitive and have a greater impact on the society as a result. The trustworthiness of data is important when it comes to public social networking sites like facebook and twitter. Due to the large… More >
