Once the angiogram reveals the exact nature of the problem, decisions can be made on the best form of treatment. Angioplasty usually involves opening the narrowed areas with a tiny balloon and then the insertion of a fine metallic mesh tube called a coronary stent.
Special drug-eluting stents have expanded the range and number of narrowings that can be successfully treated. Regardless, there are some narrowings which will still be best treated using coronary bypass surgery.
Angiography and angioplasty do not require a general anaesthetic. People are admitted to hospital on the day of the procedure and may be discharged in the late afternoon or stay overnight.
