1

What is hypoplasic left heart syndrome

Congenital birth defect that affects normal blood flow through the heart

2

What occurs in hypoplastic left heart syndrome

left side of fetal heart doesn't form properly during pregnancy

3

What is affected in hypoplastic left heart syndrome

left ventricle
mitral valve
aortic valve
ascending aorta
atrial septal defect present

4

Causes of hypoplastic left heart syndrome

Causes among babies are unknown, however, could be related to genetics or a combination of genes and other risk factors

5

In addition to genes what are some examples of risk factors that may cause hypoplastic left heart syndrome

Things the mother comes in contact with
surrounding environment
maternal food, drink, medication

6

Signs and symptoms of hypoplasic left heart syndrome (8)

bluish or poor skin color
cold hands and feet
lethargy
poor pulse
poor feeding
pounding heart
rapid breathing
shortness of breath

7

When is hypoplastic left heart syndrome found

before birth via ultrasound
first few hours of life to a few days after birth

8

Treatments for hypoplastic left heart syndrome

medication to strengthen heart muscle, lower blood pressure, and remove extra fluid
high-calorie formula because infants fatigue while feeding
surgery to increase blood flow and bypass poorly functioning side of heart
right ventricle becomes main pumping chamber after surgery

9

Prognosis for hypoplastic left heart syndrome

if left untreated it is fatal
surgeries do not cure syndrome but help restore heart function
can have lifelong complications
need regular follow up visits with cardiologist
if requires heart transplant, have to take medicine for rest of life to prevent rejection (immuno suppressives)

10

Another name for the Right atrium/ventricular valve

Tricuspid valve

11

Another name for the left atrium/ventricular valve

Mitral valve (bicuspid)

12

Review the anatomy of the heart

okay

13

T/F: the right and left sides of the heart operate as separate pumps

F

14

Flow of blood through the heart

Vena cava
Right atrium
tricuspid valve
Right ventricle
Pulmonary semilunar valve
Pulmonary artery
lungs
pulmenary veins
Left atrium
bicuspid valve
left ventricle
aortic semilunar valve
aorta

15

Two characteristics of blood in the aorta

O2 rich
nutrient rich

16

4 areas that stethoscopes are placed to listen to particular valves of the heart (clockwise starting at the top left)

Aortic area
pulmonic area
bicuspid (mitral) area
tricuspid area

17

Heart contractions are know as

systole

18

Heart relaxactions are known as

diastole

19

This is ventricular systole

contraction of the ventricle

20

This is atrial systole

contraction of the atrium

21

Systole when used without clarification describes this

ventricular systole

22

Duration of systole and diastole

0.3
0.5

23

Cardiac cycle characteristics (3)

less than 1 second normally
contraction faster than relaxation
atrial contraction followed by ventricular contraction

24

Normal heart rate

72 beats per minute

25

Cardiac cycle (start to finish)

Atria contracting
Blood flows into ventricles
Ventricles contract
Blood flows into atria

26

Review how pressure changes in the ventricle correlate to volume changes in the ventricle (podcast, approximately 4 min. in)

okay

27

This is used to measure pressures associated with the heart and is measured at this location on the body

blood pressure
biceps

28

This type of blood flow creates sound

turbulent

29

This type of blood flow does not create sound

Laminar

30

Starting blood pressure cuff pressure

140 mmHg
