Angiocardiography

Abstract

Advances in the study of the living human heart have been furthered by angiocardiography and progress in this technique will add much to the understanding of the subject. At present interpretation is often difficult, partly because exposures are made too infrequently and partly because of changes in heart position and chamber size in systole and diastole. Improved radiological technique, particularly means of making the exposures at selected times in the cardiac cycle and simultaneous exposures in the antero-posterior and oblique positions, will ease the difficulties and afford a clearer picture of the anatomy and dynamics of the heart in health and disease. In the fields of thoracic and cardiac surgery, wider use of angiocardiography should decrease the need for exploratory thoracotomy.
