Prenatal diagnosis is possible with ultrasonography. Complications associated with the presence of an acardiac twin include sequelae from the twin-to-twin transfusion syndrome, polyhydramnios, dystocia, ruptured uterus and congestive heart failure in the normal twin. In utero fetal therapy is possible in some instances.
