Angioplasty is a surgical intervention in which the occlusive/hypertrophied vessel or coronary artery of the heart is occluded by a balloon. This form of medical therapy is usually provided after myocardial infarction to restore arterialisation and shorten the course of damage. The surgeon puts a stent inside the lumen so that it stays patent in restoring blood flow. This early coronary angioplasty after myocardial infarction (within 3 months) also reduces future myocardial heart disease.
