Heart embryology

2. This syndrome often leads to abnormal valve function and mitral regurgitation due to weakening of heart tissues.
6. A common birth defect can occur at this valve, leading to risk of aortic stenosis.
9. This common site of ASDs forms before the ostium primum closes. Foramen ___.
11. This process occurs during Week 3-7 of pregnancy.
12. CHD characterized by overriding aorta, pulmonary stenosis, VSD and RV hypertrophy.
13. If aortic coarctation occurs before the ductus arteriosus, it is termed ___.
14. These structures develop simultaneously with the atrial/ventricular septa to achieve atrio-ventricular separation.

1. Superior portion of the primitive heart tube. ___ arteriosus.
3. Of the arterial arches, this arch does not develop into major vessel.
4. This syndrome occurs when a left-to-right shunt eventually evolves into a right-left shunt due to RV hypertrophy.
5. This type of shunt would likely manifest a blue-ish tint in the lips and tongue.
7. During primitive folding, this structure extends inferior to the primitive atrium. Sinus ___.
8. These cells migrate from the neural tube and undergo transition to initiate aorticopulmonary septation.
10. This arterial arch forms the proximal section of pulmonary arteries and ductus arteriosus.
