Cine-Angiocardiography

Right and Left Heart Biplane Cine-angiocardiography.

Technological progress in the design and construction of image intensifiers has been so rapid since their introduction by Teves (1955) and Feddema (1955) that they are already in daily use for many types of radiological examination. Though much of the pioneer work in this field was angiocardiographic (Lind, Wegelius, and Lichtenstein, 1954; Lind, Wegelius, and Boesen, 1955; Lind, Rocha, and Weg...

Left ventricular cine-angiocardiography in endocardial cushion defect.

Endocardial cushion defects are complex mal-formations with a wide clinical spectrum. The abnormalities range from a small defect of the atrial septum in the position of the ostium primum, with an abnormal cleft mitral valve, to more extensive abnormalities which include tricuspid incompetence and defects of the ventricular septum. In the most severe form a common atrioventricular canal occurs....

Interventricular septal defect shown by left ventricular cine-angiocardiography.

This study was prompted by the need felt by our surgical colleagues for more accurate localization of the defect in the interventricujlar septum, as a high proportion of children undergoing operation for closure of these defects was noted to have large or multiple defects. Defects in the interventricular septum occur both in the membranous and muscular parts of the septum, and they may be singl...

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...
