The arterial sheath is introduced through the wrist or groin . The concerned area will be numbed using local anaesthetics such that the patient does not feel any pain or discomfort.

The whole procedure lasts for 15-20 mins.

Once the procedure is over, the arterial sheath is carefully removed and the punctured site is covered. The patient is taken to the recovery area where he/she is monitored for any complication. Once the patient is stable he/she can be discharged after 3/4 hours or shifted to their own room.
