Mitral gradient | definition of mitral gradient by Medical dictionary
the diastolic pressure difference between the left atrium and left ventricle.
the difference in pressure in the left atrium and left ventricle during diastole.
mi·tral gra·di·ent (mī'trăl grā'dē-ĕnt)
During diastole, difference in pressure between left atrium and left ventricle. A normal mitral valve does not impede the flow of blood from left atrium to left ventricle during (ventricular) diastole; pressures in left atrium and left ventricle during diastole are therefore equal.
