  • Connecting stalk and become continuous with vessels in chorion
  • Somites and their derivatives

Question 14

Question
All of the following statements are true regarding atrial septal defects (ASDs) except:
Answer
  • They are more common in females than males.
  • The most common type of ASD is patent foramen ovale.
  • Endocardial cushion defects are often isolated and rarely associated with genetic conditions.
  • The most common ASD is well tolerated through childhood and may not present with symptoms until the 30s (pulmonary hypertension).
