Coronary angioplasty AN-jee-o-plas-tee , also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery. Angioplasty is often combined with the permanent placement of a small wire mesh tube called a stent to help prop the artery open and decrease its chance of narrowing again. Some stents are coated with medication to help keep your artery open drug-eluting stents , while others are not bare-metal stents. Angioplasty can improve symptoms of blocked arteries, such as chest pain and shortness of breath.
Coronary Angiography. Stents are usually needed when plaque blocks a blood vessel. A doctor will decide whether or Insertion potential risk stent to atent a stent based on a few factors, such as the size potentlal the artery and where the blockage occurs. Stents can also lead to blood clots because the Insertion potential risk stent and arteries are delicate. Angioplasty is performed in patients with narrowed potdntial blocked blood vessels, which prevent blood from reaching the heart. Our Division of Cardiovascular Sciences oversees much of the research on stents that we fund, helping us to manage and treat ischemic heart disease and other conditions related to atherosclerosis. After your stent placement, you may need prolonged treatment with medications, such as aspirin or clopidogrel Plavix to reduce the chance of blood clots forming on Guilt nifty groups erotic stent.

- Angioplasty and stent placement are common procedures to open arteries in the heart that are clogged.
- A stent is a tiny tube that your doctor can insert into a blocked passageway to keep it open.
A stent is a tiny tube that a doctor places in an artery or duct to help keep it open and restore the flow of bodily fluids in the area.
Stents help relieve blockages and treat narrow or weakened arteries. Doctors may also insert stents in other areas of the body to support blood vessels in the brain or ducts that carry urine and bile. A stent is usually a mesh-like metal tube, although fabric stents are also available. Sometimes, doctors will use dissolvable stents coated in medication as a temporary solution. Plaque is a buildup of cholesterol , fat, and other substances found in the blood.
When this plaque collects in the bloodstream, it sticks to the walls of the arteries. Over time, this buildup narrows the arteries, limiting the amount of fresh blood that can reach the body. A buildup of plaque in the arteries is a cause of coronary heart disease. Over time, people with narrowed arteries may begin to notice warning symptoms, such as chest pain. If people with the condition do not receive treatment, they may be at a higher risk of complications, such as a heart attack or stroke.
If the artery is at risk of collapsing or becoming blocked again, doctors may recommend inserting a stent to keep it open. Doctors put a stent into an artery in a procedure known as a percutaneous coronary intervention PCI , or angioplasty with stent. During PCI, doctors will insert a catheter into the artery. The catheter has a small balloon with a stent around it on one end.
When the catheter reaches the point of the blockage, the doctor will inflate the balloon. When the balloon inflates, the stent expands and locks into place. The doctor will then remove the catheter, leaving the stent in place to hold the artery open. A doctor will decide whether or not to insert a stent based on a few factors, such as the size of the artery and where the blockage occurs.
In some cases, restenosis may occur. Restenosis is when too much tissue grows around the stent. This could narrow or block the artery again. Doctors may recommend forms of radiation therapy or opt to insert a medication-coated stent to slow the growth of the tissue. A stent can cause blood clotting, which may increase the risk of heart attack or stroke. The National Heart, Lung, and Blood Institute state that about 1 to 2 percent of people who have stented arteries develop a blood clot at the site of the stent.
Anti-clotting medications may carry their own risks and can cause irritating side effects, such as rashes. In rare cases, a person's body may reject the stent, or they may have an allergic reaction to the material in the stent. Anyone who has a known reaction to metals should talk to their doctor about alternatives. The surgeon will discuss the procedure with a person in advance, but it can help to know what to expect. A doctor will advise individuals on how they should prepare for a stent procedure.
They will give them information on when to stop eating and drinking, as well as when to start or stop taking medications before the procedure.
Anyone who has any other health conditions, such as diabetes or kidney disease, must tell their doctor. The doctor may then have to consider some additional steps. Doctors may also give the person prescriptions to fill before having the stent inserted, as they will need to start taking the medications as soon as the procedure is complete. According to the National Heart, Lung, and Blood Institute , a stent procedure only takes about an hour and does not require general anesthesia.
The person remains awake during the entire process so can hear any instructions the doctors may have. Doctors will administer medication to help the person relax. They will also numb the area where they insert the catheter. They may, however, feel a bit of pain as the balloon expands and pushes the stent into place. After placing the stent, doctors deflate the balloon and remove the catheter.
They bandage the area where the catheter entered the skin and put pressure on the bandage to help prevent bleeding. This allows hospital staff to monitor the person. During the hospital stay, a nurse will regularly check the person's heart rate and blood pressure. They may also change the dressings or clean the wound.
As the insertion site heals, it will bruise and may develop into a small knot of tissue, which is normal. The area may remain tender for at least a week. During recovery, doctors will prescribe antiplatelet drugs to help prevent blood clots from forming near the stent.
Aspirin is an antiplatelet drug that a person will need to take daily for an indefinite period after having a stent inserted. Doctors may also recommend a drug called a P2Y inhibitor. P2Y inhibitors include clopidogrel, ticagrelor, and prasugrel.
They will also provide the person with special recovery instructions, such as avoiding strenuous work or exercise while the body heals. Some stents are temporary. Doctors may use stents coated in particular medications that help break down plaque or prevent it from building up in the area. These stents will dissolve over time. While a stent may relieve symptoms, such as chest pain, it is not a cure for other underlying issues, such as atherosclerosis and coronary heart disease.
Even with a stent, a person with these conditions may need to take steps to prevent further complications. Doctors will recommend healthy lifestyle changes after inserting a stent to help prevent plaque building up in the body. Stents are often just one part of treatment. Doctors may also prescribe medications for any underlying conditions. If anyone experiences any bothersome side effects, it is best to talk to a doctor. They may recommend alternative medications or change the dose to help relieve side effects.
Doctors commonly insert stents to widen arteries and prevent complications from coronary heart disease and other conditions. While a stent may provide relief, it is only one part of a treatment program. Even with a stent, it is possible for severe complications to occur.

Insertion potential risk stent. Benefits of Angioplasty & Stenting
What is a stent? Uses, risks, and recovery
But what is stent placement, who is it for, and do the risks outweigh the benefits? Patients often receive a stent during or immediately after a procedure called angioplasty.
Angioplasty is performed in patients with narrowed or blocked blood vessels, which prevent blood from reaching the heart. In angioplasty, a small tube called a catheter with a balloon on the end travels through a blood vessel to the artery with the blockage.
Once the catheter reaches its destination, the doctor will inflate the balloon to help send the plaque causing the blockage out against the wall of the artery, allowing blood to flow normally. A stent is a tube that opens the artery and, ideally, keeps it open for the long-term.
They are normally made of a metal mesh material but can be made of fabric. If a stent is used during angioplasty, it is placed around the deflated balloon. When the doctor inflates the balloon, the stent expands to keep the passageway open. The balloon and catheter removed, but the stent remains, becoming part of the once-blocked artery.
In severe blockages, this may be a multistep process, starting with a smaller balloon and then using a larger one. Stent placement in cases of aortic aneurysms are similar, but the stent itself may be different, and the procedure is usually longer.
In these cases, the stent may be made of fabric and have at least one small hook on it. The stent tightly fits on the artery and the hook or hooks catch on to the artery walls. In both scenarios, cells will eventually grow to cover the stent, and the blood vessel will look normal again overtime.
There are two types of stents: drug-eluting stents and bare metal stents. Drug-eluting stents are coated with medicine that is continuously released into the artery long after the stent placement is over, with the goal of hopefully preventing the artery from becoming clogged again.
Bare metal stents do not have any drug coating. Patients with a high risk for bleeding may be better candidates for bare metal stents. Drug-eluting stent patients may be prescribed long-term antiplatelet medication after the procedure. These may include:. In the event that the artery still closes even with a stent, a patient may have to undergo coronary artery bypass surgery CABG.
After the procedure , patients will be prescribed at least one antiplatelet medication, which will help prevent platelets from clumping and forming blood clots, which could otherwise block the artery again. Antiplatelet agents include aspirin and a P2Y 12 inhibitor. Patients with a history of heart attack should be prescribed a P2Y 12 inhibitor for at least a year; longer duration could help reduce the risk of future heart attack.
Patients with high bleeding risk may have received a bare metal stent and could be prescribed a P2Y 12 inhibitor for at least a month.
Patients who received a drug-eluting stent could be on a P2Y 12 inhibitor from six months to one year; high-risk bleeding patients could have shorter courses of treatment, while those who do not have a significant bleeding risk may be treated for longer than a year.
Some research has suggested that the perceived benefits of stents may outweigh the reality. A study published in The American Journal of Cardiology found no difference in mortality rates between patients who underwent angioplasty alone versus revascularization with coronary stents.
The researchers evaluated data from the Duke Database for Cardiovascular Disease on 1, patients who underwent revascularization with angioplasty alone or stent placement between and Assessed outcomes included outcomes of death, myocardial infarction, and repeat target vessel revascularization TVR. Lycopene —the red carotenoid that is abundant in tomatoes —can help lower heartdisease risk, as it prevents LDL cholesterol from oxidizing.
