Selective coronary angiography using a percutaneous femoral technique.

Successful use, in 650 patients over a period of two years, of a percutaneous femoral technique of selective coronary angiography is described. This technique is carried out with the use of mouldable, manually preshaped polyethylene catheters. Preparation of the material and the different steps of the technique are discussed. Excellent flexibility and plastic memory of this catheter material allow easy, rapid and consistent percutaneous insertion and removal of catheters and intubation of the coronary arteries.
