Which murmur grade is typically described for aortic stenosis in this material?

• A. Grades 4-6
• B. Grades 1-2
• C. Grade 3 only
• D. All grades equally

Answer: (A)

Aortic stenosis tends to produce a loud, harsh systolic murmur because the blood jet rushed through a narrowed valve creates strong turbulence. In this material the description aligns with the upper end of the grading scale, typically grades 4 through 6. These grades reflect a loud murmur, often with a palpable thrill (grade 4) and, at the higher end, very loud sounds that may be heard with only part of the stethoscope on the chest (grades 5–6). So, the characteristic description you’d expect for AS in this material is a loud, high-grade murmur. Mild murmurs (lower grades) and even mid-range grades can occur, but AS is most commonly portrayed as high-grade due to the significant turbulence across the stenotic valve.
