[Determination of global and regional ventricular ejection fraction by a fully digitalized technic. Results of digital subtraction angiocardiography following peripheral venous contrast injection compared to cineventriculography, 2-dimensional echocardiography and radionuclide ventriculography].
Subtraction angiocardiography (DSAK) with a fully digitalised system (DR 960) provides a well defined demonstration of the left ventricle after peripheral venous contrast injection. Cardiac volume and ejection fractions were calculated by a dedicated software programme and the findings correlated with cine ventriculography (CA) (r = 0.91), biplane echo cardiography (2 DE) (r = 0.77) and radionucleid ventriculography (RNV) (r = 0.85); the method can be used even with reduced cardiac output (EF less than or equal to 15%). Densitometric measurements of the EF on phantoms correspond with morphometric findings, but its clinical application is at present not possible because of the frequent appearance of artefacts. Analysis of regional disturbances of ventricular wall movements shows very good correlation between DSAK and CA and these appear more accurate than 2 DE. DSAK is a valuable, rapid and reproducible method with few side effects for cardiological diagnosis.
