In another NBME (NBME Form 26), it was tested that aortic stenosis in older patients (>60 years old) is usually due to calcification and in younger patients, aortic stenosis is usually due to a congenital bicuspid valve.
Recall that it is a Crescendo-decrescendo systolic ejection murmur and has a soft S2 with a possible ejection click. It displays "pulsus parvus et tardus" or a weak pulse with a delayed peak.
