Coronary angiography by means of the percutaneous transbrachial approach.

A simplified method of coronary angiography was performed by means of the percutaneous transbrachial approach with a 5-F catheter designed for selective cannulation of the right and left coronary arteries. On 70 serial coronary angiograms, visualization of the coronary arteries was sufficient in all cases with no major complication. The preformed catheter required only simple manipulation. This method was easy, safe, and rapid in the investigation of coronary artery disease.
