Transradial percutaneous intervention is gaining increasing acceptance around the world as a viable alternative to traditional (transfemoral) percutaneous intervention because of the greater patient acceptance, the lack of need for bedrest and the lower incidence of hemorrhagic access complications.Because anticoagulation is used for the diagnostic part of the procedure and because half of all bleeding complications during percutaneous coronary intervention are non-access site bleeding, the optimal anticoagulation regimen during transradial coronary interventionis a matter of considerable interest.
