The physicians of the Children’s Heart Network draw upon their many years of experience treating congenital heart disease with their longstanding affiliations with pediatric cardiothoracic surgeons, intensive care physicians and other pediatric specialists, to best meet the needs of congenital heart patients throughout central and south Texas.
