Your coronary arteries deliver oxygen-rich blood to your heart muscle. Over time, plaque can build up in your coronary arteries and limit blood flow through them. This is known as coronary heart disease (CHD). It can damage your heart muscle and put you at risk of having a heart attack.
Accordig to healthline, a cardiac stent is used to treat narrowed or blocked coronary arteries. It can also be used to improve blood flow immediately following a heart attack. Cardiac stents are expandable coils made of metal mesh.
Your doctor can insert one during a coronary angioplasty, a nonsurgical and minimally invasive procedure. The device is designed to support your artery walls, keep your artery open, and improve blood flow to your heart.
In this article, we are going to be discussing about how a cardiac stent is inserted for people with coronary heart disease. Keep reading and enjoy while you explore new knowledge.
How is a cardiac stent inserted?
Your doctor can insert a cardiac stent under local anesthesia. First, they will make a small incision in your groin, arm, or neck. Then, they will insert a catheter with a stent and balloon on the tip.
They will use special dyes and monitors to guide the catheter through your blood vessels to the narrowed or blocked coronary artery. When they reach the narrowed or blocked area, they will inflate the balloon. This will expand the stent and stretch your artery, allowing for increased blood flow. Finally, your doctor will deflate the balloon, remove the catheter, and leave the stent behind.
During this procedure, a filter will prevent plaque and blood clots from coming loose and floating freely in your bloodstream. Following the procedure, you will need to take medications to help prevent clotting within the stent. As your artery begins to heal, your own tissue will begin to merge with the mesh of the stent, adding strength to your artery.
A particular type of stent, called a drug-eluting stent (DES), is sometimes used. It’s coated with medication to lower your risk of restenosis. Restenosis happens when your artery narrows again.
