The only disadvantages of radial is the significant Physician’s learning curve to master the technique. The complex coronary intervention which will require 7f or larger guidecatheter support is a relative contraindication for radial approach at present. However, there is significant development of hardwires like sheath less guide catheters. At present complex coronary interventions like bifurcation stenting and use of larger rotablator burrs are a reality for radial approach.

In radial approach, the radial artery is cannulated at the wrist This approach has several advantages. Local complications like entrysite hematoma and need for blood transfusion is totally eliminated, The hemostatic time is less and the patient can be mobilized early after the procedure and will be discharged early. This will reduce the cost of procedure. The radial approach has tremendous patient comfort as they may be ambulated early after the procedure.
