Abstract:
The transradial approach is the most frequent access used in France for coronarography and percutaneous coronary intervention. This access permits a reduction of local complications in comparison with femoral access. There are very few real contraindications of transradial approach. The use of Allen's test before coronarography remains controversial in the transradial catheterization community. It remains a standard practice in some institutions, however many centers have stopped using Allen's test considering that there is no evidence supporting its use.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
