title: Experience with preformed catheters for coronary angiography by the brachial approach.
abstract: Experience with a simplified technique for selective coronary angiography by the brachial cutdown approach using preformed coronary catheters in over 500 cases is described. This technique has facilitated selective catheterization of the coronary arteries in patients where use of the Sones catheter has proven difficult or impossible. Particularly, coronary arteries in patients with a dilated aortic root, high-rising left coronary artery or tortuous subclavian artery are easily catheterized with the preformed catheters described in this report. Shortened procedure time, an acceptable morbidity (1.4%) and mortality (0.2%), and improved coronary opacification by virtue of the ease in selectively entering the coronary ostia make these preformed catheters a useful modification to coronary angiography by the transbrachial approach.
