Though stenosis of the trunk and branches of the pulmonary artery has long been reported at necropsy (Maugars, 1802; Fiirst, 1878; Schwalbe, 1909; Oppenheimer, 1938), the disorder was thought to be extremely rare. During the past decade, however, it has been recognized more often due to the introduction of cardiac catheterization and selective angiocardiography (Moller, 1953; Coles and Walker, ...

This report presents a patient with a persistent left superior vena cava demonstrated by radionuclide angiocardiography. The appearance is characteristic.

The present report deals with the findings from a total of 116 children or young adults with a right aortic arch. In all these cases the aortic arch was specifically studied at necropsy or could be located from angiocardiography. The diagnosis of the associated congenital cardiovascular lesions was established by cardiac catheterization, angiocardiography, operation, or post-mortem examination....

Six consecutive patients studied by angiocardiography or aortography ranging in age from 12 to 68 years were checked by a direct-writer type of electrocardiograph during the procedure. The clinical entities consisted of pulmonary stenosis, coarctation of the aorta, aneurysm of the ascending aorta, ventricular septal defect (2 cases), and atrial septal defect associated with complete transpositi...

The minute has given way to the second as an expression of radiographic exposure duration. It is predicted that the millisecond will be the term of the future. Arterial blood velocity exceeds 50 cm. per second. In cardiovascular radiography, especially angiocardiography, maximum detail cannot be achieved unless the x-ray exposure is short enough to "stop" rapid movement. Practical experience in...

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 ...

SELECTIVE angiocardiography as a practical means of delineating anatomic details of cardiac malformations has been advanced by the development of contrast agents with greater radiopacity, lower viscosity, and less apparent toxicity. The severe immediate reactions of collapse, so common with older media, are rarely seen today; many patients, however, still have vomiting, intense headache, and ot...

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...

Cardiac catheterization and angiocardiography studies are reported in two patients with syphilitic aortic aneurysms, both of which compromised the pulmonary circulation. In the first instance the right main pulmonary artery was compressed and pulmonary hypertension proximal to the compression resulted. In the second patient the aneurysm ruptured into the pulmonary artery producing an aortic-pul...
