What is twin-to-twin transfusion syndrome?
Twin-to-twin transfusion syndrome (TTTS) is rare and results from disproportionate blood supply between two (or more) identical fetuses that share a single placenta. One twin, the donor twin gives away more blood than it receives and has a risk of malnourishment and organ failure. The recipient twin receives too much blood and risks overworking the heart and other cardiac complications.
