The most common cause of aortic stenosis in adults is a degenerative process associated
with many of the risk factors underlying atherosclerosis. Aortic stenosis may cause
a heart murmur.
Recommendation parameters for aortic stenosis include the severity of the diagnosis
and the presence of signs or symptoms.
Certification/Recertification — Aortic Stenosis
Minimum — 3 months if post surgery
NOTE: If more than one waiting period applies (because of multiple
cardiac conditions or other comorbid diseases), examine the driver for certification
after the completion of the longest waiting period.
Maximum certification period — 1 year
Recommend to certify if:
The driver has:
- Mild aortic stenosis that is asymptomatic.
- Moderate aortic stenosis that is asymptomatic and the driver has
no disqualifying findings and/or conditions.
- Severe aortic stenosis that has been surgically repaired and meets
all aortic valve repair
Recommend not to certify if:
The driver has moderate aortic stenosis with one or more of the following:
- Heart failure.
- Atrial fibrillation.
- Left ventricular dysfunction with ejection fraction less than 50%.
The driver has severe aortic stenosis regardless of symptoms or left ventricular
- 5 years if mild aortic stenosis.
- 1 to 2 years if moderate aortic stenosis.
The driver should have an annual medical examination.
