Angiocardiography

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...

Clinical value of angiocardiography.

Filling of the heart chambers and great vessels with contrast substance reveals their anatomical structure, and permits differentiation of vascular from non-vascular mediastinal lesions. The method, contrast substance used, and procedure, have been described. Angiocardiography has revealed that our knowledge of the position of the heart chambers and the border-forming structures of the cardiac ...
