A Window to Life: A Rare Association of a Small, Proximal Aortopulmonary Window With Pulmonary Atresia/Ventricular Septal Defect.

• PA/VSD has always been associated with either a PDA or MAPCAS. • PA/VSD can exist in the absence of a PDA or MAPCAS via a small APW. • PA/VSD with a small APW can be managed successfully with a Blalock-Taussig shunt.

Myopericarditis after messenger RNA Coronavirus Disease 2019 Vaccination in Adolescents 12 to 18 Years of Age.

Objectives: To characterize the clinical course and outcomes of children 12-18 years of age who developed probable myopericarditis after vaccination with the Pfizer-BioNTech (BNT162b2) coronavirus disease 2019 (COVID-19) messenger RNA (mRNA) vaccine.

Study Design: A cross-sectional study of 25 children, aged 12-18 years, diagnosed with probable myopericarditis after COVID-19 mRNA vaccination as per the Centers for Disease Control and Prevention criteria for myopericarditis at 8 US centers between May 10, 2021, and June 20, 2021. We retrospectively collected the following data: demographics, severe acute respiratory syndrome coronavirus 2 virus detection or serologic testing, clinical manifestations, laboratory test results, imaging study results, treatment, and time to resolutions of symptoms.

A multicenter survey on post-transplant lymphoproliferative disorders in pediatric heart transplant recipients: A case for development of consensus guidelines for screening, surveillance, and treatment?

Post-transplant lymphoproliferative disorders (PTLD) are the main malignancy seen after pediatric heart transplant and are a significant cause of morbidity and mortality. Prior to the development of detailed guidelines, we sought to identify trends in screening, diagnosis, and treatment of pediatric PTLD. All Pediatric Heart Transplant Society (PHTS) institutions were surveyed.

Neonatal management of prenatally suspected coarctation of the aorta.

Objectives: (a) To determine the false-positive rate among newborns with prenatally suspected coarctation of the aorta (CoA) within the UCLA Health system, (b) to compare patient and maternal interventions and outcomes between false-positive cases and normal controls, and (c) to determine the timing of clinical presentation of CoA.

Methods: We performed a single-center, retrospective case control study of all fetuses with suspected isolated CoA who underwent both fetal echocardiographic evaluation and subsequent delivery at UCLA between January 1, 2011, and December 31, 2018. Maternal and neonatal medical records were reviewed for demographic and clinical data, for cases of suspected CoA and for controls.

Diagnosis and Treatment of Childhood Meningitis Caused by Streptococcus bovis Group.

Streptococcus bovis is a rare, but important cause of bacterial meningitis in children. Since its discovery in the early 1970s, the pathogen has undergone multiple taxonomic changes producing four distinct subspecies today, the most prevalent of which is S. gallolyticus subsp pasteurianus in infants and children.

Streptococcus gallolyticus subsp. pasteurianus infection in twin infants.

Streptococcus gallolyticus subsp. pasteurianus, previously known as Streptococcus bovis biotype II.2, is an uncommon pathogen in neonates.
