Abstract
A novel color-Doppler-directed échocardiographie technique was developed
for the determination of left ventricular (LY) peak filling rate normalized to
the end-diastolic volume (NPFR). To calculate this diastolic filling index, the
mitral valve cross-sectional area (MVA) was measured using color Doppler
inflow column width for guidance, and the LY volumes were determined by
biplane Simpson’s rule. For comparison, NPFR was measured in a similar
fashion by a non-color Doppler échocardiographie (DE) technique with MVA
determined on the gray scale image. Radionuclide angiography (RNA) was
used as a reference standard. Thirty-two patients were considered for this
study. Seven were excluded because of technical (5 cases) or pathophysiological
reasons. The mean NPFR values for color DE, non-color DE and RNA
were 2.14 ± 1.03, 2.83 ± 1.43 and 2.08 ± 1.43 s_1, respectively. There was a
fair correlation demonstrated between the non-color DE method and RNA
(r = 0.60, SEE = 1.18 s_1). On the other hand, an excellent correlation existed
between the color DE method and RNA (r = 0.85, SEE = 0.55 s-1). This
improvement was statistically significant (p < 0.05). In conclusion, the color
DE method for determination of NPFR is more reliable than the non-color
DE method in reproducing RNA results. However, DE techniques are considerably
less applicable than RNA, because 22% of the patients successfully
tested with RNA could not be studied with DE methods.
