Transradial Cardiac catheterization is an endovascular process performed through the radial artery, and used to detect, diagnose and treat arterial disease. It has a huge impact on decreasing complications and it is considered a viable alternative to the transfemoral approach. Also known as transradial access, transradial approach or transradial angioplasty, the process has gained popularity due to the technological advances in the sheath and catheter design.
