Interventional/invasive cardiology is concerned with surgery of the heart chambers and coronary arteries of the heart. Interventional/invasive cardiology is a special area of catheterization. A catheter (a thin plastic tube) is inserted into the vascular system (artery or vein) and advanced with the aid of imaging procedures as far as the heart chamber or artery to be treated.
This procedure serves primarily to widen narrowed coronary arteries, as for example in myocardial infarctions or angina, to widen the arteries of the lower extremities or the renal arteries. A mesh tube (stent) is also often used. Interventional/invasive cardiology is also used to treat certain heart rhythm disorders or to widen constrictions in the area of the heart valves.
