[Correspondence] Radial versus femoral access for cardiac catheterisation

The study by Marco Valgimigli and colleagues1 purports to add to the existing body of evidence that radial percutaneous coronary intervention is superior to procedures undertaken through the femoral artery, with less major bleeding, and lower all-cause mortality.1–3 However, closer analysis suggests that the benefit might not be driven by better outcomes in patients receiving radial access, but by poor outcomes after femoral access in centres that do these procedures infrequently.
