ANAEESTHESIA FOR ANGIOCARDIOGRAPHY

Multiple Injections for Angiocardiography.

In the past the value of angiocardiography has been limited by the practice of giving only one injection of contrast medium, so that selective angiocardiography tends to be restricted to the end of cardiac catheterization. Moreover, the use of biplane film changers permits only views strictly at right angles to one another. The newer contrast media are tolerated better than those formerly avail...

Ventricular performance after angiocardiography.

Ventricular performance was assessed before and after angiocardiography in 22 patients with normal left ventricle, mitral stenosis, aortic stenosis, and myocardial disease. The increased circulating blood volume known to occur after angiocardiography is a determinant of the increased ventricular pre-load. The after-load is unchanged. Patients with normal left ventricle and some patients with va...

Contrast agents in angiocardiography.

The electrocardiogram during angiocardiography.

It is often said that angiocardiography carries little risk, and series of more than a thousand injections without a death are on record (Sussman, 1948; Horger et al., 1951). During recent years, however, more than thirty deaths have been reported-the majority in children with cyanotic congenital heart disease. The exact cause of these deaths has still to be discovered. When Mr. R. C. Brock beg...

Equilibrium radionuclide angiocardiography.

Planar equilibrium radionuclide angiography (ERNA) is used to determine global and regional measures of ventricular function (primarily left ventricular [LV] function) at rest and/or during exercise stress or pharmacologic intervention. These measures of ventricular function may include evaluations of ventricular wall motion, ejection fraction (EF), and other parameters of systolic and diastoli...
