 At the conclusion of the procedure, the balloons, wires and catheters are removed and the vessel puncture site is treated either with direct pressure or a vascular closure device.Transradial artery access (TRA) and transfemoral artery access (TFA) are two techniques for percutaneous coronary intervention.TRA is the technique of choice for management of acute coronary syndrome (ACS) as it has significantly lower incidence of bleeding and vascular complications compared with the TFA approach.
