Abstract

30 patients with a previous myocardial infarction who had undergone diagnostic conventional left ventriculography and coronary arteriography had left ventriculography also performed by digital subtraction angiography after intravenous injection of contrast medium; the mean interval between the two investigations was 2.3 days. The conventional and the digital subtracted left ventricular images were computer-processed; global ejection fraction (obtained by the volumes calculated with the Dodge method) and segmental wall motion (from a quantitative analysis performed according to the Stanford method) were compared. We found a close correlation for the ejection fraction obtained by the two techniques (r = 0.89, p less than 0.01); absolute values proved to be slightly higher in the digital subtraction angiography. Segmental wall motion was significantly correlated too (p less than 0.05 for all the segments of the ventricular silhouette but for the one corresponding to the base of the heart). Digital intravenous angiography provides an accurate and less invasive method to evaluate left ventricular function.
