Heart: Valves Flashcards
What is the general parts of a valve?
1) Valve Orifice
2) Fibrous Ring
3) Cusps
Which valve is between the right ventricle and the pulmonary trunk?
Pumonary Valve
The pulmonary Valve contains what cusps?
1) Anterior
2) Left
3) Right
What is the valve that lies between the left ventricle and the aorta?
Aortic Valve
Which valves are known as the semilunar valves?
1) Pulmonary
2) Aortic
Which valves will separate the left ventricle and atrium which contains two (anterior and posterior) cusps?
Bicuspid/Mitral Valve
Which valves is located between the right atrium and ventricle and contains three cusps (anterior posterior and septal)?
Tricuspid Valve
What are the other names of the mitral and tricuspid valves?
Right and Left Atrioventricular Valves
What produces the “lub” sound of the power stroke?
contraction of the ventricles and closure of the tricuspid and mitral valves
What produces the “dub” sound of the power stroke?
the closure of the pulmonary and aortic valves
Where would one listen for the pulmonary valve on patient evaluation?
Of the left 2nd internsoctal space
Where is the pulmonary valve located topographically?
At the medial end of the left 3rd costal cartilage
What is the location of the aortic valve topographically?
Behind the left half of the sternum and medial tot eh 3rd intercostal space.
Where would you listen to the aortic valve on patient evaluation?
Over the right second intercostal space
Where is the mitral valve located topographiclly?
behind the left half of the sternum and medial to the fourth costal cartilage.
where would you listen to the mitral valve when evaluating a patient?
Over the left 5th intercostal space at eh midclavicular line
Which valve is listened to farthest away from the actual valve?
Mitral Valve
Why do we nit listen to the valves directly over their actual location?
1) Location of bone
2) Orientation of the heart
3) The blood carries sound when it is moved through the heart
What is location of the tricuspid valve topographically?
Behind the right half of the sternum medial to the 4th intercostal space.
Where is the tricuspid valve most audible?
Over the left 5th intercostal space at its boarder with teh sternum
Which valve is the most frequently diseased?
Tricuspid
Why is the tricuspid valve the most frequently diseased?
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.
What do the pulmonary and aortic valves lack when compared to the mitral and tricuspid valves?
Chordae Tendinae and papillary msucles
