BSA — m²
Integrated, stepwise grading of AS severity (incl. discordant AVA and gradient)
AdvancedVersion 2026.10.1
Steps from morphology and gradient through AVA, measurement review, flow status and EF to the low-flow, low-gradient subgroups. Discordance is resolved by sequence, not by majority vote.
Quick reference:↑ Aortic stenosis
Applicability
- Native aortic valve stenosis. Prosthetic valves follow the prosthetic-valve document.
- Blood pressure should be recorded; evaluate ideally when BP is normal, since hypertension alters velocity and gradient.
- Step 0 — morphologyDoes 2D imaging show stenotic aortic valve disease (calcific thickening with reduced motion, doming, or commissural fusion)?Stenotic morphology on 2D — Thickened calcified cusps with reduced motion, doming congenital valve, or fused rheumatic commissuresValve morphology not recorded.
