Description
Summary:In an attempt to learn more about the physiologic changes in the cardiovascular system during angiocardiography and the nature of mixing of radio-opaque dyes with blood, radiopotassium and Diodrast I dilution curves were obtained before and during angiocardiography. Studies in patients without vulvuar disease and with mitral valvular disease indicated an increased cardiac output during angiocardiography, but the increases were not statistically greater than those following control injections. No difference in indicator-dilution patterns of potassium and Diodrast was demonstrable, suggesting identical circulatory mixing pattterns.
