The role of the transradial approach for complex coronary interventions in patients with acute coronary syndrome

Abstract

Despite advances in antithrombotic and antiplatelet therapy, bleeding complications remain an important cause of morbidity and mortality in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). A significant proportion of such bleedings are related to the access site, and adoption of transradial access (TRA) may reduce these complications. In patients with ST-segment elevation myocardial infarction (STEMI), TRA reduced cardiac mortality in comparison with the femoral approach (TFA). High-risk patients such as women, obese patients and elderly subjects who are at increased risk for vascular complications and bleeding, might particularly benefit from the TRA. However, specific radial expertise providing procedural time and a success rate comparable to those with the TFA are strongly recommended before using this technique in the emergency setting.
