Pediheart Podcast #388: The Proteomic Signature Of The Adult Fontan Patient

This week we delve again into the world of adult congenital heart disease and specifically the realm of biomarkers when we review a recent report of the proteomics of the adult Fontan patient. What is proteomics and how can this inform our understanding of the pathophysiology and adaptive pathways of the Fontan circulation? Are there meaningful differences in the patterns of protein expression between the adult Fontan patient and control 2 ventricle subjects? What might account for differences and how can we understand these differences to explain outcomes in the Fontan adult patient? We speak with the first and senior authors of this week's work, Professor Alexander Opotowsky of the University of Cincinnati and Mr. Ismael Assi who is a Sarnoff Fellow and soon to be 4th year medical student at the University of Cincinnati. DOI: 10.1016/j.jacadv.2026.102810
