What is a Cardiac Stent and when is it used?

A cardiac stent is a small, metal mesh tube that is used to treat coronary artery disease (CAD), a type of heart disease that occurs when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to a build-up of plaque.

During a procedure called percutaneous coronary intervention (PCI), a healthcare provider will insert a thin, flexible tube called a catheter into a blood vessel, usually in the groin, arm, or neck. The catheter is then guided through the blood vessel to the area of the blockage in the coronary artery.

Once the catheter is in place, a balloon attached to the catheter is inflated, pressing the plaque against the walls of the artery and widening the artery. The balloon is then deflated and removed.

A cardiac stent is then placed in the artery to help keep it open. The stent is made of metal mesh and expands to fit the size of the artery. It is usually coated with a medication that helps prevent the artery from becoming blocked again.

Cardiac stents are typically used to treat CAD that cannot be treated with lifestyle changes and medications alone. They are generally safe and effective, but like any medical procedure, they can have risks and complications. It is important to follow any instructions provided by your healthcare provider and to inform them of any problems or concerns.
