aortic causes
Last reviewed 09/2021
Left ventricular ejection murmurs are maximal at the aortic area, lower left sternal edge and apex. Possible causes include:
- aortic stenosis (valvar, subvalvar, supravalvar)
- hypertrophic obstructive cardiomyopathy
- increased stroke volume e.g. ASD
- aortic cusp sclerosis
- bicuspid aortic valve with no obstruction
- coarctation of the aorta - a coarctation murmur, when heard anteriorly, can be confused with an ejection murmur
- post-valvar dilation eg aortic aneurysm, hypertension
An ejection systolic murmur may occur in aortic regurgitation due to increased blood flow.
