    #456 - [Journal Club] - 🫀 From The Heart - Do These Newborns Have Diastolic Dysfunction, or Just Different Physiology?

    Send us Fan Mail In this prospective study, Adrianne and Nim dig into an area with almost no normative pediatric data: right ventricular diastolic function. Comparing 57 infants with RV pressure overload after intervention for pulmonic stenosis or tetralogy of Fallot to 134 healthy controls, the authors found a consistent pattern, reduced beat-to-beat variability, a higher atrial contribution to filling, and an E/A ratio inversion that was nearly universal in the CHD group versus about half of controls. It's one of the first real attempts to define what a right-sided diastolic pattern actually looks like in this population. But without a comparison against cardiac catheterization, the hosts agree the findings are hypothesis-generating at best, a starting point for a multi-parametric approach, not a reason to skip an invasive workup. ---- Echocardiographic Markers of Right Ventricle Diastolic Dysfunction in Neonates and Infants with Congenital Heart Disease.

    #456 - [Journal Club] - 🫀 From The Heart - Why Does a Sicker Mom Sometimes Mean a Stronger Neonatal Heart?

    Send us Fan Mail In this small prospective pilot study, Adrianne and Nim explore a domain rarely discussed on rounds, how a mother's cardiovascular function in preeclampsia shapes her newborn's circulatory transition. Using maternal echo and neonatal electrical cardiometry across 13 mother-baby dyads, the authors found an inverse relationship: the worse the mother's cardiac function, the higher the neonate's cardiac output, though vascular tone barely budged. It's a compelling hypothesis about placental strain and fetal adaptation. But Nim pushes back hard on the methodology, pairing this paper with a companion study showing electrical cardiometry consistently overestimates cardiac output in neonates, and questioning why daily echoes were performed on these babies but the results never reported. ---- Linking maternal and neonatal circulation in preeclampsia. Piani F, Annesi L, Degli Esposti D, Vincenzi S, De Crescenzo S, Della Gatta AN, Simonazzi G, Corvaglia L, Martini S.Am J Physiol Heart Circ Physiol. 2026 Mar 1;330(3):H708-H716. doi: 10.1152/ajpheart.00945.2025.

    #456 - [Journal Club] - 🫀 From The Heart - Why Is CHD Mortality Rising Again After 15 Years of Progress?

    Send us Fan Mail In this retrospective national study, Adrianne and Nim look at 25 years of congenital heart disease mortality in the US using CDC WONDER data. Infant mortality remains staggeringly high (54 per 100,000), and after years of steady decline, it has been climbing again since 2014. Disparities run throughout: higher deaths among males, non-Hispanic Black and American Indian/Alaska Native populations, and in rural, Midwestern regions, pointing more to gaps in access and resources than to disease biology. The conversation also flags a growing, under-discussed problem, an aging adult congenital population outpacing the pediatric one for the first time, with too few specialists trained to care for them. ---- National Trends and Disparities in Congenital Heart Disease Mortality in the United States, 1999-2024.Raja S, Albrahim MMS, Aldhafeeri BF, Omar AA, Alqadeeb BA, Alhuways MM, Bangaryd AA, Alqahtany MG, Alfaraj AB, Almughyir RS, AlRasheed ST, Alfaifi M.  Pediatr Cardiol. 2026 Jan 13. doi: 10.1007/s00246-025-04156-1.

    #456 - [Journal Club] - 🫀 From The Heart - Should an Abnormal Brain MRI Change the Decision to Operate in Critical CHD?

    Send us Fan Mail In this systematic review and meta-analysis, Nim and Adrianne dig into just how common brain injury really is in neonates with critical congenital heart disease. Pooling 31 studies spanning two decades, the authors found that nearly 70% of these babies show some form of ischemic brain injury, split roughly between pre-operative and post-operative timing. Counter to what most clinicians would predict, kids who went to surgery earlier (days 4-6) had higher rates of white matter injury than those who waited longer. MRI remained the most sensitive tool for picking up these lesions, well ahead of ultrasound or CT. But the data stops well short of proving these findings predict long-term outcomes, and Nim pushes back on the idea that an abnormal scan alone should steer decisions about whether to operate. ---- Prevalence of Ischemic Brain Injury in Neonates With Congenital Heart Disease: A Systematic Review and Meta-Analysis. Kim C, Chetan D, Kazazian V, Alzamil J, Chau V, Seed M, Miller SP, Selvanathan T.Neurology. 2026 Feb 10;106(3):e214569. doi: 10.1212/WNL.0000000000214569.

    #454 - PEEP, Tidal Volume, and Physiology, How Far Has Resuscitation Science Traveled? (ft Dr. Charles Roehr)

    Send us Fan Mail How far has delivery room ventilation really come? In this special episode, recorded in collaboration with the Neonatal Resuscitation Symposium, Ben sits down with Dr. Charles Roehr, professor of neonatology and perinatal medicine at the University of Bristol, clinical trialist at the University of Oxford, and member of ILCOR. Together they trace the evolution of respiratory support at birth, from the era of fixed inflation breaths to today's focus on physiologic stability and gentle cardiopulmonary transition. Dr. Roehr reflects on a quarter century of resuscitation science, the enduring challenge of human factors in the delivery room, and where the field may be heading, from better intrapartum monitoring to increasingly specialized resuscitation teams. Dr. Roehr will be delivering a keynote, "Optimizing Effective Ventilation Strategies in the Delivery Room," at the Neonatal Resuscitation Symposium, taking place September 10 to 11 at Indiana University in Indianapolis.

    #453 - [Neo News] - 📌 Are You Still Assuming Every Newborn Got Vitamin K?

    Send us Fan Mail Vitamin K refusal has crossed 5%. That's one in twenty babies, and the curve is bending the wrong way. Ben and Eli work through a new Pediatrics case review that opens with a warning shot, that hemorrhagic presentation in an infant should no longer be a diagnostic mystery, alongside a JAMA letter tracking refusal from 2.9% in 2017 to 5.2% in 2024. Eighty-one times the risk. Intracranial hemorrhage in most late-onset cases. Twenty percent mortality. They talk about the halo effect on other refusals, the ICD code you should be using, and why this conversation belongs in the obstetrics office, not the nursery. ---- Vitamin K Deficiency Bleeding After Refusal: A Sentinel Event in a Misinformation Era.
