Present Status of Biplane Cineangiocardiography

Abstract

Biplane cineangiocardiography has been performed with two 9-inch image intensifiers coupled at right angles to each other. The images on the output phosphors of the intensifiers are photographed by synchronized 35 mm motion picture cameras. Over 300 examinations have been undertaken in patients with clinical problems such as left-to-right shunts, right-to-left shunts, aortic valvular and subvalvular disease, mitral valvular disease, endocardial fibroelastosis, and many other congenital and acquired cardiac lesions. Biplane cine studies obviate the problem of chamber overlap, permit precise structure identification in two planes, and afford maximal information with a single dose of contrast agent. The method may now be considered a tested and feasible technique of exploring anatomic and physiologic changes in the cardiovascular system.
