Tiny Heart Case Studies

Why did the Doctor recommend Lucas be born via Caesarean section?

• The baby had an elevated heart rate during contractions which meant it was under stress

• The baby's oxygen levels were too low due to a decreased heart rate

• The baby had an elevated heart rate which meant it was getting too much oxygen

• The mothers heart rate at rest was much higher than during contractions which meant the baby was under stress

Why was the newborn's phalanges colored blue?

• His breathing rate was fast and still not getting enough oxygen

• His breathing rate was low, so he was not getting enough oxygen

• His heart was too large for his body

• His heart was beating too slow and giving him too much oxygen

Compare Lucas' vital signs to normal babies.

• His heart rate is high, but his blood pressure is low

• His heart rate and blood pressure are both low

• His heart rate and blood pressure are both high

• His heart rate is high but his blood pressure is normal

How did the doctors treat Lucas when he was in the ICU as an infant?

• small tubes were inserted into his heart valve that slowly inflated to open the valves

• A cadaver's heart valve was used to replace Lucas' old heart valve

• A prosthetic valve was used to replace Lucas' old heart valve

• A small piece of rubber was placed in Lucas' heart valve to prevent it from leaking

What is one "negative" about using a balloon angioplasty to treat Lucas?

• Eventually the balloon will lose elasticity and no longer work. Therefore, it is not a permanent solution

• The valves will eventually re-close. Therefore, it is not a permanent solution

• It is highly dangerous to perform on children, because they have smaller hearts than adults

• The procedure can only be done one time

Why do pulmonary valves last longer than aortic valves?

• Their connective tissue is thicker which means they are stronger

• They are tricuspid valves where aortic valves are monocuspid

• They are under less physical strain than aortic valves

• They are closer to the lungs, so they are more oxygen rich
