Comparing flow and pulmonary artery growth post-patent ductus arteriosus stenting in patients with ductal-dependent pulmonary flow using 4D magnetic resonance imaging.

Aims: The 4D magnetic resonance imaging (4D-flow MRI) provides a qualitative and quantitative assessment of cardiovascular structures and processes. 4D-flow MRI was used to study pulmonary flow in post-patent ductus arteriosus (PDA) stent insertion in duct-dependent pulmonary flow neonates at baseline (PDA stent insertion) and after 6 months, and also, to evaluate the effect of flow dynamics on the growth of pulmonary arteries (PAs).

Methods And Results: This prospective observational study included neonates with ductus arteriosus-dependent pulmonary circulation who underwent ductal stenting between June 2021 and November 2022.

Native Aortic Valve Infective Endocarditis Secondary to Community-Acquired Methicillin-Resistant Staphylococcus aureus: A Case Report and Literature Review.

Infective endocarditis (IE) refers to a microbial infection affecting either a heart valve or endocardium, resulting in tissue damage and the formation of vegetation. Native aortic valve endocarditis in children is rare and is associated with serious complications related to valvular insufficiency and systemic embolizations. As reports about community-acquired methicillin-resistant (MRSA) native aortic valve endocarditis in children are very scarce, we report this case along with a literature review about its complications and management.

Device Closure of Superior Sinus Venosus Atrial Septal Defects: A single centre experience.

Sinus venosus atrial septal defects present a wide variety of anatomical features and are frequently associated with partial anomalous pulmonary venous drainage of one or more right pulmonary veins. Surgical correction used to be the standard treatment. In recent times, transcatheter correction of superior sinus venosus atrial septal defects has come into vogue.

Blalock-Taussig Shunt versus Ductal Stenting as Palliation for Duct-Dependent Pulmonary Circulation.

Objectives: There is limited data published from outside North America and Europe comparing the outcomes of a modified Blalock-Taussig shunt (MBTS) and ductal stenting as the first palliative procedure for infants with duct-dependent pulmonary circulation. This study reports the National Heart Center's, in Muscat, Oman, experience in comparing the outcomes of these 2 interventions.

Methods: This retrospective study included all infants with duct-dependent pulmonary circulation who received either a MBTS or ductal stenting from 2016-2019.

Cause of profound hypoxemia following a bilateral bidirectional Glenn shunt: Clue suggested by agitated saline echo contrast.

Following a bilateral bidirectional Glenn shunt, a child had persistent hypoxemia. Agitated saline contrast injection into the jugular vein during transesophageal echocardiography displayed a rapid appearance of saline particles in the cardiac chambers suggesting the presence of pulmonary arteriovenous malformations. However, the clinical picture was not in agreement and an angiographic contrast injection during an immediate cardiac catheterization revealed the underlying pathology which was immediately corrected surgically.

Identifying Anomalies of Systemic Venous Drainage: Systemic Venous Anomalies; Atrial Morphology.

So as to produce totally anomalous systemic venous connection, all of the systemic venous tributaries, along with the coronary sinus, should be connected with the morphologically left atrium. Previous descriptions of this rare constellation of anomalous connections of the systemic venous tributaries of the heart have been compromised by the inclusion of individuals having isomeric atrial appendages. In these settings, most frequently, the totally, or almost totally, anomalous systemic venous connections are associated with a sinus venosus defect.

Hybrid Subxiphoid Perventricular Approach as an Alternative Access in Neonates and Small Children Undergoing Complex Congenital Heart Interventions.

The hybrid subxiphoid perventricular approach provides direct access through the heart and may alleviate the technical limitations of complex percutaneous interventions particularly in infants with low body weight. We present the outcomes from a tertiary cardiology center using this approach. We performed a retrospective review of all patients less than 15 kg who underwent a hybrid perventricular approach via a small subxiphoid incision.

Chronic Q Fever Endocarditis in an Omani Child: The First Pediatric Case Report from Oman.

Q fever endocarditis is the most common presentation of chronic infection of but it rarely occurs in the pediatric age group. We report the first case of Q fever endocarditis in an Omani child. The affected 11-year-old female lives in the Al Batinah governorate in the north of Oman and was known to have congenital heart disease.

Percutaneous axillary artery approach for ductal stenting in critical right ventricular outflow tract lesions in the neonatal period.

Objectives: We aimed to assess the experience using a percutaneous axillary artery approach for insertion of arterial ductal stents in patients with critical right ventricular outflow tract lesions at two tertiary pediatric cardiology centers.

Background: Patent ductus arteriosus stenting is an accepted palliative alternative to BT shunts for neonates with critical right heart lesions. Access to tortuous ductus' may be challenging via the femoral artery, whereas the carotid artery presents a low risk of stroke.

An overlooked complication of vancomycin induced acute flaccid paralysis in a child with acute leukemia: a case report.

Vancomycin is a glycopeptide antibiotic which is commonly used to treat methicillin-resistant staphylococcal infections. It is commonly used in pediatric oncology wards for children with febrile neutropenia. We report a very rare side effect of vancomycin induced myopathy in a child with acute lymphoblastic leukemia.
