Opening editorial for the BMC Anesthesiology collection: recent advances in anesthesia for congenital cardiac diseases.

Congenital cardiac anesthesia has evolved substantially over recent decades, contributing to improving outcomes and survival for patients with congenital heart disease (CHD). BMC Anesthesiology has initiated a new Collection, Recent Advances in Anesthesia for Congenital Cardiac Diseases, to highlight emerging research and encourage large-scale studies addressing knowledge gaps, implementation barriers, and future opportunities in the field.
