Transradial percutaneous coronary intervention in acute myocardial infarction

Although transradial coronary intervention is widely applied for percutaneous procedures, its safety in the setting of ST-segment elevation myocardial infarction (STEMI) is controversial. The benefit of transradial approach in terms of reducing access site complications is well documented. However, higher rate of procedural failure and longer procedural times reported by some authors raise concerns regarding its applicability in STEMI. Our aim was to review the safety and efficacy of transradial coronary intervention versus transfemoral intervention in acute ST-elevation myocardial infarction. This review focuses on key aspects of safety and efficacy: adverse ischemic and bleeding events, reperfusion times and radiation exposure.
