Complications of Selective Angiocardiography

Radiology, 1960
With the rapid development of surgical procedures for the treatment of congenital and acquired cardiovascular defects, the need for more precise radiographic methods for the anatomical demonstration of the cardiovascular system has become increasingly apparent.

Hemodynamic Effects of Angiocardiography

Investigative Radiology, 1966
Hemodynamic alterations following angiocardiography were studied during 136 injections of sodium iothalamate in 80 adults. The average dose was 0.5 ml/kg. Systemic blood pressure uniformly fell, beginning 13 sec after left heart injection and returning to the control level after 60 sec.

A Thresholding for Radionuclide Angiocardiography

Investigative Radiology, 1981
A thresholding algorithm for nuclear angiocardiographic studies is presented. The algorithm is free of operator intervention. The threshold is defined on the basis of the distribution of picture elements with decreasing count rates during systole. The application is valid for first-pass and equilibrium ECG gated studies.

EVALUATION OF ANGIOCARDIOGRAPHY

Journal of the American Medical Association, 1943
This report summarizes the examination of 100 persons by the Robb-Steinberg method.1The patient material comprises the groups included in the accompanying table. Many of the patients suffered from other ailments, such as hemiplegia due to hypertensive cardiovascular disease, diabetes mellitus, nephritis and the like.

Angiocardiography in Constrictive Pericarditis

Chest, 1974
The conventional x-ray film examinations and the angiocardiographic features of 13 cases of constrictive pericarditis are analyzed and compared with those in five cases of pericardial effusion and four cases of congestive cardiomyopathy. The conventional x-ray film examination can contribute to the diagnosis of constrictive pericarditis if the ...

Angiocardiography in pulmonary disease

The American Journal of Surgery, 1955
I N 1938 a practical method of visualizing the chambers of the heart, the pulmonary circulation and the great blood vessels during life (nomcalled angiocardiography) was introduced.lJ This was followed by detaiIed descriptions of the opacified CardiovascuIar structures in health and disease, so that in the ensuing sixteen years the importance of ...

A Syringe Heater for Angiocardiography

Radiology, 1961
Rapid development of effective surgical methods for correcting congenital and acquired cardiovascular lesions has created a need for precise roentgen demonstration of the cardiac chambers. Increasing experience with angiocardiographic technics has shown the diagnostic advantages of the selective injection of contrast medium through accurately ...

Quantitative radionuclide angiocardiography

Cardiovascular and Interventional Radiology, 1987
Quantitation of cardiac pump function using radionuclide angiocardiography provides objective information for the management of patients with heart disease. Left and right ventricular ejection fraction, stroke volume ratio, ejection rate, diastolic function, ventricular volume, parametric imaging, amplitude and phase analysis, and shunt quantification ...

Note on an Apparatus for Angiocardiography

The British Journal of Radiology, 1948
The increasing use of contrast media for the demonstration of cardiac abnormalities has created new problems in radiology. It is usually necessary to take ten or more films at one second intervals. Many special devices have been developed to solve this problem, and the apparatus to be described has the merit of being comparatively simple to construct ...
