Noninvasive assessment of left ventricular diastolic function: comparative analysis of Doppler echocardiographic and radionuclide angiographic techniques

J Am Coll Cardiol. 1986 Mar;7(3):518-26. doi: 10.1016/s0735-1097(86)80461-2.


This investigation was performed to determine whether variables obtained directly from the Doppler left ventricular diastolic flow velocity profile provide a reliable estimate of diastolic function. Measurements of diastolic flow velocity obtained by Doppler echocardiography were compared with volumetric measurements of left ventricular diastolic filling determined by radionuclide angiography in 12 subjects without cardiac disease and in 25 patients with a variety of cardiac diseases. The two methods were in agreement in distinguishing normal from abnormal diastolic function in 21 (84%) of the 25 patients with cardiac disease, identifying diastolic function as normal in 8 and abnormal in 13 of these patients. Good correlations were observed between certain Doppler variables of left ventricular diastolic flow velocity and radionuclide angiographic variables of left ventricular filling. The time interval from the aortic closing component of the second heart sound to the end of the early diastolic flow velocity peak, assessed with Doppler echocardiography, correlated well with the time interval from end-systole to the end of rapid filling, assessed with radionuclide angiography (r = 0.83). Descent of the Doppler early diastolic flow velocity peak correlated well with the radionuclide angiographic peak filling rate (r = 0.79). The ratio between the heights of the early and late (due to atrial systole) peaks of diastolic flow velocity showed good correlation with the ratio between percent of left ventricular filling during rapid filling and during atrial systole (r = 0.76). These findings demonstrate that the left ventricular diastolic flow velocity profile obtained with Doppler echocardiography compares favorably with radionuclide angiographic variables in the evaluation of left ventricular diastolic function.(ABSTRACT TRUNCATED AT 250 WORDS)
