Summary: Infective endocarditis is common in patients with corrected congenital heart disease, but rarely found on surgical patches used to close atrial septal defects. However, in the case of mitral valve endocarditis, the situation could be different as it can cause severe mitral insufficiency and seed the surgical patch. It is important to accurately evaluate cardiac structures when a systemic infection is detected in CHD patients, even if the defects have been surgically corrected, as detection and eradication of infectious foci and surgical reintervention are particularly challenging in this subpopulation.

Summary: This study compared the effectiveness of two surgical approaches (2-patch repair and modified single-patch repair) for complete atrioventricular septal defects and evaluated their impact on left atrioventricular valve function. The results showed that MSP provides similar left atrioventricular valve competence to TP in the absence of deep VSD.

Summary: This study evaluated the impact of left-to-right shunt in type II atrial septal defect patients on left and right ventricular volumes, function, and strain using cardiovascular magnetic resonance imaging. The findings showed that the shunt resulted in RV overfilling, LV underfilling, and impaired systolic RV performance associated with longitudinal dysfunction of the interventricular septum.

Summary: In this study, the authors introduced a new implantation technique called the FAST technique, which can efficiently close simple and complex ASDs. This technique overcomes the left disc malalignment to the septum in defects with absent aortic rims and avoids complex implantation maneuvers and the risks of injuring the pulmonary veins.

Summary: This paper investigates the conductivity, dielectric, and microwave properties of SrNbxYxFe12-2xO19 hexaferrites synthesized by the citrate sol-gel method. The study evaluates key parameters related to the electrical and dielectric functions of the hexaferrites, and finds that the co-substitution ratio greatly affects the dielectric parameters but has a minimal influence on conductivity mechanism. Microwave properties and activation energy are also measured and calculated.

Summary: This article investigates the synthesis, structural features, magnetic properties, and microwave properties of hard/soft SrNiZr/CFO nanocomposites. The samples were prepared using a sol-gel auto-combustion approach and their structural characteristics were verified through XRD, SEM, TEM, and HR-TEM techniques. The magnetic measurements showed good exchange coupling between the hard and soft phases at room temperature, but weak coupling at low temperature. The electromagnetic properties and the correlation with the magnetic phase ratio were also analyzed.

Summary: The study explored the photocatalytic degradation of Acid Red 26 using graphitic carbon nitride (g-C3N4) catalyst and UV-A light. Both synthetic and actual municipal wastewater showed high clearance rates, although the degradation was slower in wastewater due to its complex chemical composition. Intermediate products were identified using liquid chromatography-mass spectrometry (LC-MS), and the importance of reactive species (h⁺ and O-2⁻) in the degradation process was demonstrated.
