چکیده
normal subjects and iii patients with ilomiregurgitanit heart disease yielded a similar contour. This suggested that in the albseimce of reour-itation the pallameters of the distal (arterial) curve ca.n be predicted fromm the proximlmai ( pulm1nomary artery) culve.

Some theoretical aspects of quantification of mitral valve regurgitation by the indicator-dilution method; sufficient and insufficient experiments.
I curves have been used in the past for the determination of cardiac output," measurement of so-called cardiopulmonary or central blood volume," detection of intracardiac shunts," and, more recently, in an attempt to quantify valvular insufficiency." Despite the extensive literature which has accumulated and which has been recently reviewed by Dow, a complete, theoretical analysis of the indica...
متن کاملAn appraisal of the double indicator-dilution method for the estimation of mitral regurgitation in human subjects.
T HE shape of an indicator-dilution curve is determined by at least 4 variables: cardiac output, the volume between the injection site and the sampling site, the presence of a left-to-right intracardiac shunt, and the presence of valvular regurgitation.1-3 In the absence of an intracardiac shunt and valvular regurgitation, one can predict the downslope of the arterial dilution curve, using the ...

Indicator dilution technique is more widely used during cardiac catheterization for the diagnosis and rough estimate of the size of intracardiac shunts and valvular regurgitation (Korner and Shillingford, 1955; Fox and Wood, 1957; Swan and Wood, 1957; Woodward et al., 1957; Shillingford, 1958; Carter et al., 1959; Carleton et al., 1960; Jose et al., 1960). Evans blue dye (T-1824) has long been ...
متن کاملArterial blood flow patterns in human subjects and their effect on indicator dilution curves from various arterial sites.
Indicator dilution curves obtained from various systemic arterial sampling sites are commonly used for analysis of blood flow, cardiac shunts and valvular regurgitation, and for study of segments of the blood volume. It is generally assumed that the contour of such curves is largely determined by the passage and dilution of the indicator in the central circulation and that changes occurring dur...
