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

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.
