Abstract
Congenital heart disease (CHD) is a significant global health issue affecting millions of children. This manuscript provides a detailed examination of the status of CHD surgery in Thailand, encompassing geographical facts, demographic considerations, the burden of CHD, availability of services, organization of delivery, funding mechanisms, training of surgeons, support services, outcome data, and a glimpse into the future of CHD surgery in the country. Above all, the lessons to be learned are critical to helping CHD surgery programs to be lifelong and sustainable.
