Q

What is the general parts of a valve?

A

1) Valve Orifice
2) Fibrous Ring
3) Cusps

2
Q

Which valve is between the right ventricle and the pulmonary trunk?

A

Pumonary Valve

3
Q

The pulmonary Valve contains what cusps?

A

1) Anterior
2) Left
3) Right

4
Q

What is the valve that lies between the left ventricle and the aorta?

A

Aortic Valve

5
Q

Which valves are known as the semilunar valves?

A

1) Pulmonary

2) Aortic

6
Q

Which valves will separate the left ventricle and atrium which contains two (anterior and posterior) cusps?

A

Bicuspid/Mitral Valve

7
Q

Which valves is located between the right atrium and ventricle and contains three cusps (anterior posterior and septal)?

A

Tricuspid Valve

8
Q

What are the other names of the mitral and tricuspid valves?

A

Right and Left Atrioventricular Valves

9
Q

What produces the “lub” sound of the power stroke?

A

contraction of the ventricles and closure of the tricuspid and mitral valves

10
Q

What produces the “dub” sound of the power stroke?

A

the closure of the pulmonary and aortic valves

11
Q

Where would one listen for the pulmonary valve on patient evaluation?

A

Of the left 2nd internsoctal space

12
Q

Where is the pulmonary valve located topographically?

A

At the medial end of the left 3rd costal cartilage

13
Q

What is the location of the aortic valve topographically?

A

Behind the left half of the sternum and medial tot eh 3rd intercostal space.

14
Q

Where would you listen to the aortic valve on patient evaluation?

A

Over the right second intercostal space

15
Q

Where is the mitral valve located topographiclly?

A

behind the left half of the sternum and medial to the fourth costal cartilage.

16
Q

where would you listen to the mitral valve when evaluating a patient?

A

Over the left 5th intercostal space at eh midclavicular line

17
Q

Which valve is listened to farthest away from the actual valve?

A

Mitral Valve

18
Q

Why do we nit listen to the valves directly over their actual location?

A

1) Location of bone
2) Orientation of the heart
3) The blood carries sound when it is moved through the heart

19
Q

What is location of the tricuspid valve topographically?

A

Behind the right half of the sternum medial to the 4th intercostal space.

20
Q

Where is the tricuspid valve most audible?

A

Over the left 5th intercostal space at its boarder with teh sternum

21
Q

Which valve is the most frequently diseased?

A

Tricuspid

22
Q

Why is the tricuspid valve the most frequently diseased?

A

Due to the pressure that is generated in the left ventricle and thus it will begin to calcify to adapt to the stress put upon it.

23
Q

What do the pulmonary and aortic valves lack when compared to the mitral and tricuspid valves?

A

Chordae Tendinae and papillary msucles
