The transradial approach for coronary angiography was introduced twenty years ago. Since then, considerable advancements have been made in this technique that proved to be effective in many interventional procedures and in several, even high-risk patient subsets (acute coronary syndromes, elderly, fully anticoagulated and obese patients). The main advantage of transradial approach over transfemoral approach is represented by the striking reduction in the rate of access-related vascular complications and bleedings. In recent years, bleeding prevention has become an issue of paramount importance, since recent large trials and registries clearly showed that bleedings are associated with major adverse events at follow up. Nevertheless, the prevalence of transradial approach for coronary procedures worldwide is still quite low and nowadays, in the United States, the favourite strategy for bleeding prevention is mostly based on the adoption of new antithrombotic drugs (such as bivalirudin and fondaparinux) rather than on the selection of an alternative, safer vascular access route. In this review we deal with several clinical and technical issues about transradial approach, including: 1) patient selection; 2) cath lab set-up, access technique and dedicated hardware; 3) reaching the coronary ostia: how to deal with anomalous anatomy; 4) selection and manipulation of catheters; 5) haemostasis and post-procedural issues. |
