GM1 MED.B.010 Cardiovascular system ED Decision 2019/002/R MITRAL VALVE DISEASE (a) Minor regurgitation should have evidence of no thickened leaflets or flail chordae and left atrial internal diameter of less than or equal to 4.0 cm. (b) The following may indicate severe regurgitation: (1) LV internal diameter (diastole) > 6.0 cm; or (2) LV internal diameter (systole) > 4.1 cm; or (3) Left atrial internal diameter > 4.5 cm. (c) Doppler indices, such as width of jet, backwards extension and whether there is flow reversal in the pulmonary veins may be helpful in assessing severity of regurgitation.
