Angioplasty is an interventional cardiovascular technique used to dilate coronary arteries that are blocked or narrowed due to atherosclerotic plaques. Most angioplasty procedures these days incorporate a metal mesh insert, or stent, into the artery.

Coronary heart disease is the leading cause of death in many countries around the world. In which, mainly coronary atherosclerosis leads to coronary artery occlusion. Therefore, the advantages of coronary angiography, dilation and stenting techniques have solved the problems of coronary artery disease.

When advanced atherosclerotic plaque narrows the coronary artery > 70%, the coronary artery is not able to supply oxygen to the myocardium, especially during exercise, exercise or strenuous work. This causes myocardial ischemia with manifestations of angina, fatigue, shortness of breath...

Coronary artery disease occurs when one or more branches of the coronary arteries are narrowed or blocked, reducing myocardial perfusion. If not detected and treated promptly, the disease can lead to many dangerous complications.
