Is there any pain involved in a percutaneous transluminal coronary angioplasty?

A little: There is some discomfort in the location where the catheter is inserted (groin, arm, or wrist), but the skin is locally anesthetized to minimize this. There is discomfort when the dilating balloon is inflated, but you are sedated to minimize this and it's always <60 seconds. Otherwise, it doesn't hurt. Most people who have been through it will tell you it's really not bad.

Sedation helps!: There is some pain like a small needle stick and burning sensation when local anesthesia is injected around the artery. There may be some chest pain for the few seconds when the balloon is inflated. There may be momentary pinching type pain when artery is closed or some discomfort when pressure is applied on the artery. Some people with arthritis have back or joint pain from lying on the table.
