  • She also allowed parts of herself to circulate through the doctor's body along with his unoxygenated blood.

    Charlotte's Nexus

  • Transposition of the aorta and pulmonary artery, which results in the heart's recirculating unoxygenated blood out to the body, used to be fatal about 90 percent of the time, but now has a 90 percent survival rate after surgery.
