Obstruction of a coronary artery causes chest pain and breathing problems. This can lead to heart attack and death in rare cases. This kind of disease is called a cardiovascular disease and is caused by the accumulation of fatty deposits on the surface of the artery walls.
The best way to treat a coronary heart disease is by a PTCA (Percutaneous Coronary Intervention). This surgery is also known by other names, such as: "Coronary Angioplasty", "Transluminal Dilatation" and "Percutaneous Transluminal Coronary Angioplasty".
This operation is sometimes simply referred to as a stent surgery in which a metal device is placed inside the blood vessel. A coronary stent is simply a little tube with a net like structure and a balloon inside it. It is used to release blood flow inside a blocked artery. This operation must be performed by a board certified surgeon.
