Percutaneous Trans-luminal Coronary Angioplasty
A PTCA or angioplasty is a treatment for angina. A coronary angiogram is performed to confirm the presence of coronary artery disease or a narrowing in the heart arteries. A narrowing can reduce the blood flow to the heart causing angina.
The main stay of therapy for coronary artery disease is medical therapy. In some cases there is a pattern of narrowing that is amenable to PTCA. The procedure is performed in a similar fashion to an angiogram. A fine wire is passed through the narrowing and over this wire a special balloon can be passed that is inflated to open up the artery. In most cases a stent is also delivered which is a fine metal scaffolding that acts to prevent the narrowing returning.
These procedures are undertaken by Cardiologists who specialise in this field of work.
