Abstract Relational databases are still important in modern times due to their many advantages, such as ease of interaction, simplicity and data integrity. In this regard, structured query language (SQL) and technical knowledge about database schemas are the basic building blocks for retrieving information from relational databases. Generally, non-expert users cannot skillfully write technical queries on the target database. To this end, many database natural language interfaces (NLIDB) have been developed to greatly facilitate users. However, each system provides a different interface for new users, so beginners can use different interactive modes to enter keyword-based queries. For users, migrating from one… More >

Abstract Sinus venosus defects include two varieties, superior and inferior sinus venosus defects. The superior sinus venosus defect is characterized by abnormal communication between two closely related venoatrial structures: 1) the normally positioned superior vena cava-right atrium complex and 2) the right pulmonary vein-left atrium complex that is displaced leftward, forward and upward. Inferior sinus venosus defects primarily involve the inferior vena cava-right atrial junction while the right pulmonary vein-left atrial junction can also be affected. Because of the rarity and wide variation of the defects, the morphological characterization of sinus venosus defects is inconsistent among investigators and often inaccurate. Modern… More >

Abstract Objectives: To detail the US multi-institutional experience with the Occlutech^© (Occlutech International AB, Helsingborg, Sweden) atrial flow regulator (AFR) in children and adults with acquired or congenital heart disease. Background: The creation of a long-term atrial communication is desirable in several cardiovascular disease phenotypes, most notably pulmonary arterial hypertension, disorders of increased left ventricular filling and increased cavopulmonary pressures in patients with a Fontan type circulation. Methods: Patients were identified for inclusion from the AFR device manufacturer database. Data was collected using a RedCap database following IRB approval. 8 weeks of follow up data was sought for each patient based… More >

Abstract Background: Reversibility of pulmonary hypertension (PH) is closely related to the treatment options for and prognosis of children with congenital heart disease. Objective: We combined patient-specific clinical features including diagnosis, age and echocardiographic results, and biomarkers of pulmonary vascular dysfunction to explore the noninvasive methods that can be used to accurately evaluate the reversibility of pulmonary hypertension in congenital heart disease (PH-CHD). Methods: Based on the preoperative systolic pulmonary arterial pressure (sPAP), 70 CHD patients were divided into normal, PH-CHD suspected, and confirmed groups. Additionally, biomarkers of circulating endothelial cells (CECs), endothelin-1 (ET-1), and endothelial nitric oxide synthase (eNOS) were… More >

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 >
