Epidemiology and Incidence Interpretation
While there is encouraging global growth in pediatric heart transplants, these numbers remain a stark lottery of geography and age, where a child's survival still too often hinges on being born in the right country and getting sick young enough to be prioritized, yet not so sick that they join the tragic 20% who die waiting.
