Radial access for cardiac catheterization was first described by Radner in 1948,1 but it was not until 1989 that Campeau published the first series of 100 patients who underwent coronary angiography by a radial approach,2 while in 1993 Kiemeneij and Laarman reported the first three cases in which stents were placed by this route.3 At that time there was little confidence in the radial approach, due to the high failure rate and frequent need for crossover to femoral access, and so the femoral approach continued to be preferred in most centers. One of the main reasons for the poor results of radial access was the inappropriate way in which operators accustomed to the femoral approach handled radial puncture and catheterization. Another important factor was the lack of material such as puncture needles, hydrophilic introducers and diagnostic and interventional catheters designed specifically for radial access, which only came on to the market some years later.4 In the last 10 years there has been a considerable increase in the volume of percutaneous interventions using the transradial route, and it is now the first choice for coronary angiography and percutaneous coronary interventions in Europe and in many other countries. In Portugal, radial access went from 4.1% of procedures in 2004 to 57.9% in 2013,5 and according to the National Registry of Interventional Cardiology (RNCI) the figure was 75.5% in 2016.6
