Recent clinical and technological advances are transforming pediatric cardiology. Developments include improved cardiac magnetic resonance imaging techniques leveraging temporary external pacing, and the integration of genetic analysis with cardiac MRI to better assess prognosis in pediatric nonischemic heart failure. Research also highlights advancements in neonatal intensive care focusing on sedation positioning, fetal autopsy trends, and pulmonary embolism prognosis in children. These innovations are enhancing diagnostic precision and therapeutic strategies in vulnerable pediatric populations.
