Abstract
The method of choice for coronary arteriography is believed to be selective individual catheterization of each main coronary artery with cinefluorographic filming according to the Sones technique. This study is believed indicated in patients in whom there is a real question as to whether coronary disease is present, and those who have disabling angina and are therefore potential surgical candidates. There are few contraindications for patients who are not bedridden. Standard cinefluorographic equipment was used. Although catheterization of the coronary arteries was sometimes difficult and time consuming, several maneuvers were found helpful in the problem cases. Satisfactory opacification of the coronary artery was obtained in 98 of the last IOO cases. The incidence was considerably lower in the first 50. There have been no deaths and no myocardial infarctions that could be even remotely attributed to the arteriography. There were 2 cases of ventricular fibrillation which were successfully treated. The radial pulse was lost in 3 of the first 31 patients and in none of the next 119.
