Abstract:
Pulsed wave Doppler echocardiograpdy was performed in eighteen cases with chronic mitral regurgitation(CMR)and 21 normal individuals td detect the quantitative changes of the mitral diastolic flow spectrum.The results showed that the pseudonormalization of mitral flow spectrum in CMR was actually caused by impaired left ventricle(LV)active relaxation and decreased LV compliance:It thus masked the LV diastolic dysfunction in CMR.E-wave pressure gradiant(E-PG),A-wave pressure gradiant(A-PG),isovolumic relaxation time(IVRT),E deceleration time(E-DT)and LV filling time(LVFT)in CMR group were significantly different in from those in normal group(P<0.01).Therefore it is essential to integrate these parameters as the indexes to evaluate the LV diastolic dysfunction in CMR.
