With more than 26 decades of collective experience shaped by a firm dedication to always improve the care of patients with congenital heart disease (CHD), Boston Children's Department of Cardiac Surgery never hesitates to take on the most difficult and rare cases as well as the most common ones. Whether it's for complex conditions such as single-ventricle defects and heart anatomies, pulmonary vein stenosis, and aortic valve disease, or for more common conditions such as complete atrioventricular (AV) canal defect, tetralogy of Fallot, and septal defects - we achieve favorable outcomes while treating more than four times as many patients than most pediatric heart centers in North America.
