Percutaneous preformed single catheter coronary arteriography and its complications--10,000 cases

The single preformed catheter has offered an alternative to the conventional approaches to study of the coronary circulation and ventriculography. It has the advantages of being introduced percutaneouly without multiple changes for routine study or for provocative drug testing such as for spasm with Ergonovine maleate or muscular bridges with nitroglycerine. It requires no arteriotomy and has been associated with a low complication rate.
