81431-9

LOINC code 81431-9 identifies "Regurgitation degree Aortic valve Angiography". Angiography is one method for determining the degree of aortic valve regurgitation. The Sellers grading system, originally published in 1964, is based on the opacification of the left ventricle and is still used today. The Sellers grading system is as follows: 1) + = evidence of a jet of regurgitant contrast material without opacification of the left ventricle; 2) ++ = evidence of a regurgitant jet with faint opacification of the left ventricle; 3) +++ = dense opacification of the left ventricle without a distinct visible jet; and 4) ++++ = left ventricle is opacified more densely than the aorta.

This code measures Regurgitation degree in Aortic valve. It belongs to the CARD.PROC class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
