Routine use of fluoroscopic guidance and up-front femoral angiography results in reduced femoral complications in patients undergoing coronary angiographic procedures: an observational study using an Interrupted Time-Series analysis.

Transradial access is increasingly used for coronary angiography and percutaneous coronary intervention, however, femoral access remains necessary for numerous procedures, including complex high-risk interventions, structural procedures, and procedures involving mechanical circulatory support. Optimising the safety of this approach is crucial to minimize costly and potentially life-threatening complications. We initiated a quality improvement project recommending routine fluoroscopic guidance (femoral head), and upfront femoral angiography should be performed to assess for location and immediate complications.
