Congenital Heart Disease Studies

Congenital heart disease encompasses structural defects of the heart present at birth, affecting roughly 1 in 100 live births and ranging from minor septal anomalies to complex malformations requiring surgery in the first days of life. Epidemiological research tracks how patients fare across the entire lifespan—from fetal detection and early cardiac intervention through to adult life with repaired or palliated anatomy—measuring outcomes such as mortality, ventricular function, and neurodevelopmental trajectories that can be altered by both the disease itself and the physiological stress of surgery. Advances in cardiac surgery and procedures like pulmonary valve replacement have dramatically improved survival, meaning the adult congenital heart disease population is now larger than ever, raising new questions about long-term cardiac decline, the burden of reintervention, and how best to stratify mortality risk in aging patients. Active research continues to refine understanding of which fetal and neonatal factors predict later outcomes, and how complex palliative pathways such as the Fontan procedure shape cognitive, cardiovascular, and quality-of-life endpoints across decades.
