Stent implantation in the coronary arteries is a medical procedure performed during cardiac catheterization to open narrowed or blocked coronary arteries. A small, wire mesh-like stent is inserted into the affected artery via a catheter and expanded there to keep the vessel open and improve blood flow to the heart muscle.

A stent is a small tube made of metal or plastic mesh that is used to keep a narrowed or blocked coronary artery open. Stents are implanted to improve blood flow to the heart, reduce chest pain, and minimize the risk of a heart attack, especially in patients with coronary artery disease.
Before a stent implantation, patients usually receive specific instructions that include fasting before the procedure, pausing certain medications, and planning for a recovery period after the surgery. It is important to follow all instructions from your cardiologist and clarify any questions before the procedure.
Stent implantation is performed using a catheter, which is usually inserted into an artery in the leg or arm. The catheter is navigated through the vascular system to the coronary arteries, where the stent is placed at the desired location and expanded to keep the vessel open.
The risks of stent implantation include bleeding at the catheter entry site, infections, allergic reactions to the contrast agent, heart rhythm disturbances, and in rare cases, blood clots can form in the stent, which can lead to re-blockage of the vessel. The risks can be minimized by careful preparation and follow-up care.
After the implantation of a stent, patients are usually kept in the hospital for a short time for monitoring. It is important to follow the instructions for taking blood thinners exactly to prevent the formation of blood clots. Most patients report a significant improvement in their symptoms, such as chest pain, and a follow-up examination is recommended to monitor the function of the stent.
