  9. Which anomaly will cause an enlarged right atrium plus an apically displaced tricuspid valve?
    Ebstein anomaly
  10. What is UHL Anomaly?
    A total absence of right ventricular myocardium resulting in apposition (things being side by side) of the endocardium & epicardium.

    1%
  16. What is situs solitus?
    Normal body configuration
  17. When the fetal heart is in the right thorax & the abdominal organs are not arranged properly, what is the name of this?
    Situs ambigus
