Chronic aortic regurgitation: integrated severity

Version 2026.10.1

Counts the specific criteria for mild (6) and severe (7) (≥4 each), then quantifies intermediate cases (RVol, RF, EROA; Grade I–IV) only with valid measurements. Contradictory, unreliable or insufficient data give an indeterminate or incomplete result.

Applicability

Native valve with chronic AR. Prosthetic and repaired valves, and acute regurgitation, are outside the algorithm.
AR is graded by integrating specific signs and measurements; no single parameter produces a grade. Poor image quality or discordant parameters give an indeterminate result.
Quantitative parameters are used only when valid for the study (holodiastolic timing, jet geometry, no shunt or second regurgitant valve for stroke-volume methods, hemispheric PISA).

State whether the valve is native and the regurgitation chronic.
