Flashcards in Aortic Stenosis Deck (10)
What is aortic stenosis.
A pressure gradient between the LV and aorta >50mmHg or aortic orifice
What is the heart's response to aortic stenosis. (3)
LV muscle hypertrophy.
Decreased stroke volume.
What is in increased demand in aortic stenosis.
What are the causes of aortic stenosis. (3)
Senile calcification of the valve is the commonest cause.
Congenital(William's syndrome, bicuspid valve).
What are the symptoms of aortic stenosis. (9)
Heart failure (usually after 60).
Systemic emboli if infective endocarditis.
What are the clinical signs of aortic stenosis. (9)
Narrow pulse pressure.
Slow rising pulse.
Heaving, non-displaced apex beat.
Ejection systolic murmur (heard best over the aortic valve in expiration and it may radiate to the carotids).
Soft S2 (normal S1). .
Paradoxical splitting of S2.
4th heart sound.
What is seen on the ECG of a patient with aortic stenosis. (4)
LV hypertrophy and strain.
Poor R wave progression.
LBBB or complete AV blok.
What is the differential for a patient with aortic stenosis. (3)
Ischaemic heart disease.
What is seen on the CXR of a patient with aortic stenosis. (3)
Calcified aortic valve.
Post-stenotic dilatation of ascending aorta.
