Bilateral Ductus Arteriosus With Anomalous Origin of the Right Pulmonary Artery and Coarctation of the Aorta.

We present a full-term neonate with a postnatal diagnosis with a left aortic arch, bilateral ducti, and discontinuous branch pulmonary arteries with right pulmonary artery arising from right duct. Upon left ductal constriction, the patient experienced coarctation of the aorta, illustrating the importance of careful and serial interrogation of rare cardiac anatomy.

Swimming With Sharks: Left Main Coronary Obstruction Following Transcatheter Aortic Valve Implantation.

Delayed coronary obstruction (DCO) occurs when there is obstruction of the coronary ostia following a transcatheter aortic valvular implantation (TAVI). It is an uncommon but serious complication that often leads to death, usually presents as severe hypotension after TAVI, and should be suspected if migration of the valve occurs. We report the case of a 70-year-old female patient with severe aortic stenosis who underwent TAVI using a 26-mm CoreValve Evolut Pro (Medtronic, Dublin, Ireland).

Disparities in surgical outcomes of neonates with congenital heart disease across regions, centers, and populations.

Objective: To summarize existing literature on neonatal disparities in congenital heart disease surgical outcomes and identify potential policies to address these disparities.

Finding: Disparities in outcomes for neonatal congenital heart surgery were largely published under four domains: race/ethnicity, insurance type, neighborhood/socioeconomic status, and cardiac center characteristics. While existing research identifies associations between these domains and mortality, more nuanced analyses are emerging to understand the mediators between these domains and other non-mortality outcomes, as well as potential interventions and policies to reduce disparities.

Computational Modeling of the Interaction of Silver Clusters with Carbohydrates.

Silver nanoparticles are recognized for their numerous physical, biological, and pharmaceutical applications. In the present study, the interaction of silver clusters with monosaccharide molecules is examined to identify which molecule works better as a reducing agent in the application of a green synthesis approach. Geometry optimization of clusters containing one, three, and five silver atoms is performed along with the optimization of α-d-glucose, α-d-ribose, d-erythrose, and glyceraldehyde using density functional theory.
