For many years, percutaneous coronary intervention (PCI) was performed almost exclusively via transfemoral (groin) access. Over the years, there has been a significant trend towards transradial (wrist) access. Transradial access (TRA) is considered the standard in many parts of the world but in the United States, adoption has been slower. That said, the percentage of procedures that are performed radially in the US has increased steadily over the last decade, reaching approximately 30% in current practice.
