What is Coronary Angioplasty?

The term Angioplasty means using a balloon to stretch open a narrowed or blocked artery. However, most modern angioplasty procedures also involve inserting a short wire-mesh tube, called a stent, into the artery during the procedure. The stent is left in place permanently to allow blood to flow more freely.
Coronary Angioplasty is sometimes known as percutaneous transluminal coronary angioplasty (PTCA). The combination of coronary angioplasty with stenting is usually referred to as percutaneous coronary intervention (PCI). A catheter is a thin, flexible tube which is inserted into a coronary artery. The balloon at the tip of the catheter is blown up at the narrowed section of artery to force it wider. A small tube (a stent) is left in place to keep the artery widened.

When a coronary angioplasty is used?

Like all organs in the body, the heart needs a constant supply of blood. This is supplied by blood vessels called the coronary arteries.In older people, these arteries can become narrowed and hardened (known as atherosclerosis), which can cause coronary heart disease.If the flow of blood to the heart becomes restricted, it can lead to chest pain known as angina, which is usually triggered by physical activity or stress.While angina can often be treated with medication, a coronary angioplasty may be required to restore the blood supply to the heart in severe cases where medication is ineffective.Coronary angioplasties are also often used as an emergency treatment after a heart attack.

What are the benefits of a coronary angioplasty?

In most cases, the blood flow through the coronary arteries improves after an angioplasty. Many people find that any symptoms they had significantly better and they’re able to do more than they could before the procedure.If you’ve had a heart attack, an angioplasty can increase your chances surviving more than clot-busting medication (thrombolysis) can and the procedure can also reduce your chances of having another heart attack in the future.

How a coronary angioplasty is performed?

A coronary angioplasty is performed using local anesthetic, which means you will be awake while the procedure is carried out. During an angioplasty, a thin, flexible tube called a catheter will be inserted into one of your arteries through an incision in your groin, wrist or arm. This will be guided to the affected coronary artery using a continuous X-ray video. When the catheter is in place, a thin wire is guided down the length of the affected coronary artery, over which a small balloon will be delivered to the affected section of the artery. This is then inflated to widen the artery, squashing fatty deposits against the artery wall so that blood can flow through it more freely when the deflated balloon is removed. If a stent is being used, this will be provided ready-prepared around a balloon before it’s inserted. The stent will expand when the balloon is inflated and it will remain in place when the balloon is deflated and removed. A coronary angioplasty usually takes between 30 minutes and two hours. If you are being treated for angina, you will normally be able to go home later the same day or the day after you have the procedure, but you will need to avoid heavy lifting, strenuous activities and driving for at least a week. If you have been admitted to hospital following a heart attack you may need to stay in the hospital for several days after the angioplasty procedure recovers from the heart attack before going home.

How safe is coronary angioplasty?

Coronary angioplasty is one of the most common types of treatment for the heart. Around 75,000 procedures are performed in England each year. Coronary angioplasties are most commonly performed in people who are 65 years of age or older as they are more likely to have heart disease. As the procedure does not involve making major incisions in the body, it is usually carried out safely in most people. Doctors refer to this as a minimally invasive form of treatment. The risk of serious complications from a coronary angioplasty is generally small, but this depends on factors such as your age, your general health and whether you have suffered a heart attack. Serious problems that can occur as a result of the procedure include excessive bleeding, a heart attack, and a stroke.
