160 Section 3 Cardiovascular Disease Figure 16.30 Semi‐quantitative assessment of mitral insufficiency

VetBooks.ir (a) using the color flow Doppler mapping method in two dogs
suffering from degenerative mitral valve disease of various grades
(left parasternal apical four‐chamber views). In (a), the color flow
jet of mitral insufficiency (arrow) involves less than 20% of the left
atrial chamber, which is consistent with mild valvular regurgitation.
Conversely, in (b), the color flow aliased turbulent jet of mitral
insufficiency (arrow) fills 100% of the left atrial chamber, which is
consistent with severe valvular regurgitation. LA, left atrium; LV, left
ventricle; RA, right atrium; PV, pulmonary vein.
