A retrospective analysis of almost 2.8 million PCIs carried out in the U.S. between 2007 and 2012 found radial access procedures increased significantly over the time period. By the third quarter of 2012, 16.1% of procedures used transradial access. Transradial PCI resulted in better success rates and fewer complications than traditional transfemoral procedures, according to the study, but it tended to be offered to lower-risk patients. "The patients at highest risk for access site bleeding and vascular complications after PCI are those who stand to gain the most from the radial approach," wrote SCAI fellows Dr. Sunil Rao, also a study author, and Dr. Mitch Krucoff in an American Heart Association editorial.
