Abstract
Opacification of the coronary arteries has been accomplished by direct needle puncture of the ascending portion of the thoracic aorta via a suprasternal approach and injection of highly-concentrated radiopaque medium. Experience with 35 attempts in 31 patients at such coronary opacification is described. The electrocardiographic observations, the reactions, and the complications incident to the study are discussed. Thirteen of the 31 patients had some type of intrapericardial cardiac surgery subsequent to this procedure, and the surgical observations regarding the status of the coronary arteries are compared with the coronary arteriographic findings.
