In the United States, more than one million cardiac catheterization procedures are performed each year for diagnostic and therapeutic purposes.

▪ Right heart catheterizations allow for direct measurement of right-sided cardiac and pulmonary hemodynamics while left heart catheterizations provide a diagnostic and therapeutic role in those with coronary artery disease.

▪ In 1989, Lucien Campeau proposed the use of a smaller caliber catheter to access the small radial artery as a way to reduce the rates of bleeding complications.

▪ Advantages of utilizing the transradial artery (TRA) approach over the transfemoral artery (TFA) approach include: – Improved patient quality-of life metrics. – Reduced major bleeding and access site complications. – Lower total hospital costs.

▪ Access-site complications including radial artery occlusion and arteriovenous fistula (AVF) formation from TRA are rare and usually of minimal clinical impact.

▪ AVF may present with pain and edema at the puncture site, a pulsatile thrill, and/or visible dilated superficial veins.
