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.

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.

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.

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.

What if communication were treated as a procedure, something we train for and get feedback on, just like an intubation?  In this episode of Neo News, Eli Cahan talks with Dr. Jessica Fry of Northwestern University and Lurie Children's Hospital about her NeoReviews piece, "Recognizing Communication as a Procedural Skill in Neonatology." Dr. Fry shares the personal loss that shaped her career, the ethical stakes of getting family communication right, and how trauma-informed care can guide something as simple as how we address parents on rounds. They discuss the critical first 48 hours after admission and how simulation-based training can build real skill over time. A candid look at a skill every NICU provider uses daily, and how we can all get better at it.
