Brief Summary

The purpose of the study is to directly compare two methods of evaluating heart function at the time of your angiogram. In both methods contrast dye is injected into the main heart chamber during the angiogram while x-ray images are taken. One method uses an automatic power injector to deliver the normal volume of contrast; the other method uses hand injection of very low volume of contrast into the main heart chamber. It is hypothesized that hand injection will prove to be an accurate method to estimate ejection fraction (EF) at the time of radial coronary angiography when compared directly to Power LV.
