Angioplasty, also known as transluminal coronary angioplasty, is a medical procedure used to open narrowed or blocked heart arteries. It's a type of percutaneous coronary intervention (PCI) procedure.

Angioplasty involves inflating a tiny balloon to enlarge the artery and allow for better blood flow. A wire mesh tube, called a stent, is sometimes left in the artery to help keep it open.

Angioplasty is typically used to treat coronary artery disease, which is caused by a buildup of plaque in the coronary arteries. Plaque is made up of fats, cholesterol, cellular waste products, calcium and other substances. It can narrow the arteries and reduce blood flow to the heart.

When angioplasty is used to treat coronary artery disease, it can improve blood flow to the heart muscle and reduce the risk of a heart attack. It can also help relieve chest pain, often called angina, and improve quality of life.

Angioplasty can also be used to treat other conditions that involve narrowed or blocked blood vessels, such as peripheral artery disease and carotid artery disease.

Angioplasty is a minimally invasive procedure that is done in a hospital or specialized heart center. It typically takes between 30 to 90 minutes and involves inserting a catheter (a thin, flexible tube) into a blood vessel in the groin or arm and guiding it to the narrowed artery.

During the procedure, a small balloon is then inserted through the catheter and inflated to open the blocked artery. Sometimes a stent is placed in the artery to keep it open.

The recovery time after angioplasty depends on the type and severity of the procedure. Generally, most people can go home within 24 hours after the procedure and return to normal activities after a few days.
