Abstract

Intravenous digital ventriculography before and after pacing was compared with equilibrium gated nuclear ventriculography at rest and after exercise. Specifically, the relative abilities of the 2 techniques to detect resting and stress-related wall motion abnormalities were tested. Twelve normal patients and 28 patients with coronary artery disease (CAD) were tested. Neither technique produced a new wall motion abnormality in a patient with normal coronary arteries. Six patients with CAD had a history of a myocardial infarction (MI); an abnormality at rest was present in all 6 by both techniques. Of the 22 patients with CAD and a normal baseline ventriculogram, a wall motion abnormality developed in 18 during digital ventriculography with pacing; a wall motion abnormality developed in 15 with exercise nuclear ventriculography. Wall motion abnormalities by nuclear ventriculography (performed in the left anterior oblique projection) tended to be apical; digital ventriculography (performed in the right anterior oblique projection) more often produced an abnormality of the anterior or inferior wall, which could be predictive of coronary anatomy. Thus, the 2 techniques are substantially equivalent for the detection of wall motion abnormalities in CAD. © 1984.
