A hole in the heart sounds incredibly scary, however the prognosis is good. "The outlook for children who have atrial septal defects (ASDs) or ventricular septal defects (VSDs) [a hole in the heart] is excellent," according to the UCSF Department of Pediatric Cardiothoracic Surgery. "Advances in treatment allow most children who have these heart defects to live normal, active, and productive lives with no decrease in lifespan."

While we still don't know what causes these defects, Schroeder is definitely not alone in facing the difficult news; in fact 2,118 babies in the United States are born with an Atrial Septal Defect each year, per the CDC. The news doesn't seem to have detracted at all from Schroeder's excitement to be a mom, which she has expressed many times over recent years (via Us Weekly). Luckily, she has plenty of support in the form of her two former costars, Lala Kent and Brittany Cartwright, who also are also currently pregnant (via Instagram).
