Congenital Heart Defects
We have had cases in the past that involved surgery for congenital heart defects. The heart anatomy and blood flow with these defects can be very difficult to understand. Here is a University of Kansas Medical Center website I found that lists numerous congenital heart defects. In addition to viewing normal heart diagrams next to diagrams of hearts with congenital abnormalities, you can view chest x-rays, echocardiograms, and electrocardiograms of patients with defects.
