Coronary angiography is the standard study in the anatomical diagnosis of the coronary arteries and it´s introduced by Mason Sones in 1958, who proposed the technique for the brachial artery requiring experience for the manipulation of a single catheter and needed a surgical training to perform arteriotomia. At the same time, Dr. Melvin Judkins designs preformed catheters, which bear his name, for coronary angiography by using the femoral artery approach simplifying the procedure so it had a rapid adoption, a method that was Extends to the present day [1,2]. Only in the 90 Dr. Campeau looking for alternatives to previous methods for complications such as bleeding, begins with the approach through the radial artery, which has increased in recent years. Many of the interventional cardiologists around the world who use the radial approach prefer the use of the traditional preformed catheters, Judkins being the most used, because the learning curve was performed with this type of catheter as in daily practice. Remember that they were designed for the femoral approach; Pathway different than radial due to its technique of approaching and anatomy of the artery . Coronary angiography through the radial artery has increased its popularity due to patient comfort, early ambulation and decreased risk of bleeding in the Access. So much so, that although before in the catheterization rooms when the nurse prepared the patient for the procedure, she asked "a Femoral or Radial approach? Today when the patient is prepared for coronary angiography, it is almost only question Radial? "[4-6].
