Apparatus for Serial Angiography

Serial Exercise Radionuclide Angiography

R-wave-synchronous radionuclide angiography provides time-activity curve information that is assumed to be proportional to ventricular volumes. We performed serial 2-minute time-activity curves and simultaneous Fick cardiac outputs before and during graded, maximal, supine exercise in nine normal subjects; each subject exercised without drug intervention, after nitroglycerin and after intraveno...

Rapid serial angiography: further experience.

A brief description of the machine (Fig. 1) was given in the earlier paper on this subject (Curtis, 1949), and this apparatus has been used for all the cases without modification. It was devised by Dr. E. Schuster and it enables exposures to be made at three variable speeds up to 2 frames per second. Intensifying screens are employed, and the images, each 10 in. wide by 8 in. long, are projecte...

Rapid serial angiography; preliminary report.

Serial angiography in cocaine-induced myocardial infarction.

A young man suffered an acute inferior myocardial infarction following clinical use of cocaine as topical anesthesia. Coronary angiography showed occlusion of both the posterior descending and posterolateral arteries which was resistant to intracoronary administration of nitroglycerin and verapamil, a finding consistent with thrombotic occlusion. A subsequent angiogram 3 months later showed no ...
