Angioplasty is a medical procedure used to open blocked blood vessels so that blood and oxygen can flow. There are several types of angioplasties for treating different medical issues, for example a coronary angioplasty, which is performed to allow blood to flow more freely to the heart.

Although angioplasty is a conventional and low-risk treatment, it’s always good to learn as much as you can before you undergo the procedure.

This article will focus on coronary angioplasty. You will learn about different types of angioplasty, who angioplasty is for, the risks involved, preparation and recovery guidelines, the cost of angioplasty in Hong Kong from public and private healthcare providers, and whether it’s covered by insurance.


What is angioplasty?

Angioplasty treats atherosclerosis, a buildup of plaque in the arteries. This plaque is made of fat and cholesterol and restricts the flow of blood through blood vessels. Angioplasty is a common treatment for coronary heart disease and heart attacks (also known as acute coronary syndrome). It is also called balloon angioplasty or percutaneous transluminal coronary angioplasty (PTCA).

During an angioplasty procedure, the doctor inserts a catheter into the blocked blood vessel. At the end of the catheter is a tiny deflated balloon. Once the catheter is in place, the doctor inflates the balloon, which pushes the plaque or blood clot against the sides of the artery, opening up the artery so that blood can flow.

Angioplasty procedures frequently include the placement of a stent, an expandable wire mesh tube that helps keep the artery open and prevent it from narrowing again. Some stents are coated with medications, which are released over time to prevent plaque buildup. A coronary angiography with stent is also called a percutaneous coronary intervention (PCI).

There are different types of angioplasty for unblocking blood vessels in different parts of the body.

Coronary angioplasty aka percutaneous transluminal coronary angioplasty

  • Unblocks coronary arteries, which supply blood to the heart muscle
  • Often performed on patients with coronary artery disease (CAD)
  • Can be used to treat chest pain (angina) and shortness of breath
  • Can also be used to treat heart attacks in emergency settings
  • Less invasive than open-heart surgery and cardiac bypass surgery

Peripheral angioplasty and stent

  • Unblocks blood vessels outside the coronary arteries, such as in the pelvis, arms or legs
  • Often performed on patients with peripheral artery disease (PAD)
  • Can be used to treat leg pain

Carotid angioplasty

  • Unblocks carotid arteries, which supply blood to the brain
  • Often performed on patients who have had a stroke or as a stroke-prevention treatment

Venous angioplasty

  • Unblocks veins, usually in the legs, chest or abdomen
  • Often performed on patients with venous disease such as deep vein thrombosis (blood clots)
  • Can be used to treat edema, swelling and pain in the legs

The rest of this article will focus on coronary angioplasty.

Looking for health insurance that covers angioplasty?

Who needs angioplasty?

Whether or not you need a coronary angioplasty depends on several factors. Your doctor will consider the extent of your heart disease, past treatment history, overall health, and risk factors to decide whether angioplasty is right for you.

Your doctor may decide angioplasty is the correct approach if your heart health hasn’t improved even after taking medication and making lifestyle changes, if your angina (chest pain) is getting worse, or if you have a heart attack.

You might not be a good candidate for angioplasty if your heart muscle is weak or if you have diabetes or multiple severe artery blockages. In this case, your doctor might decide that a coronary artery bypass surgery is more suitable.

Angioplasty risks

Like all medical procedures, angioplasty and stenting come with risks. Some risks are more common than others.

Common risks of angioplasty include:

  • Bleeding, bruising or infection at the catheter insertion site (typically the groin, arm or wrist)
  • Blood clots
  • Restenosis, or repeat blockage or narrowing of artery

Rare risks of angioplasty include:

  • Heart attack
  • Stroke
  • Irregular heartbeat
  • Kidney damage
  • Blood vessel damage (from the catheter)

Other risks of angioplasty include:

  • Chest pain or discomfort
  • Allergic reaction to of the contrast dye

Depending on your health condition, there may be other risks. For example, the risk of complications from angioplasty gets higher with age or if you have multiple blocked arteries, kidney disease or heart failure.

It is important to speak with your doctor beforehand if you have any questions or concerns.

How to prepare for your angioplasty

Before your angioplasty, your doctor will give you clear instructions on how to prepare. Be sure to follow their instructions.

Your doctor’s team will also perform a physical examination and go over your medical history. For a coronary angioplasty, the medical exam may include a chest X-ray, blood tests and electrocardiogram (ECG).

You might be asked to stop taking certain medications before your angiogram. You’ll be asked not to eat or drink six to eight hours before your surgery. You’ll need to bring any medication you’re currently taking to the hospital with you. You will also need to arrange for someone to take you home the day after the surgery.

Angioplasty surgery: What to expect and duration

On the day of your operation, your doctor will explain the procedure to you and have you sign a consent form. Your doctor’s team will ask you about the medication you take and any allergies or past allergic reactions you’ve had to things like contrast dye or medicines.

You’ll be given a hospital gown to wear. You will lie on a procedure table, where you will be hooked up to an ECG monitor and pulse oximeter. Your vital signs, like your heart rate, blood pressure and oxygen levels, will be monitored during the angioplasty.

An intravenous (IV) drip will be inserted into your hand or arm, through which you will receive fluids and medication, such as a sedative to relax you and anticoagulants to prevent blood clots from forming. General anesthesia is not needed for coronary angioplasties. Many patients watch what’s going on in the procedure on the monitors.

First you will have a coronary angiogram, an X-ray imaging technique that shows the blockages in your blood vessels. Some local anesthetic will be injected at site on your groin, arm or wrist. An incision will be made, and a small “introducer tube” will be inserted at the incision site. A catheter will be inserted into the tube. With the aid of X-ray imaging, your doctor will guide the catheter through your artery. A contrast dye will be injected into the catheter to reveal the blockage. You might feel a warm sensation when the dye is released, or have a funny taste in your mouth or a brief headache.

Once the blockage is identified, a guidewire will be threaded through the narrow part of the artery, followed by the catheter with a deflated balloon at the tip. If your surgery involves a stent, there will be a collapsed stent (a wire mesh tube) around the balloon. The balloon will then be inflated to push the plaque up against the artery walls to stretch the artery. The inflating of the balloon will cause the stent to expand and lock into place so it can hold the artery open.

The balloon will then be deflated and the catheter and introducer tube removed. An angiogram will be taken to assess the flow of blood after the angioplasty has been performed.

The entire procedure should take 30 minutes to a few hours. This depends on things like the number of stents that need to be inserted and the number and condition of arteries involved.

Angioplasty aftercare: Dos and don’ts

After your angioplasty procedure, you might be kept at the hospital overnight for observation.

Your doctor will advise you on any medication you must take and how to take care of your wound. They might also talk to you about ways to improve your diet and lifestyle to keep your heart healthy.

In general, you should recover and be able to resume normal activity after a week or two.

What to do:

  • Take medication exactly as prescribed
  • Keep your wound clean
  • Drink lots of fluids to flush out the contrast dye from your body
  • Make lifestyle changes to improve your heart health
    • Lose extra weight
    • Quit smoking
    • Eat a healthy diet (consider going plant-based)
    • Get regular exercise
    • Manage stress
  • Go through a cardiac rehabilitation program

What to avoid:

  • Avoid lifting heavy objects for a week
  • Avoid strenuous exercise for a week
  • Do not drive a car for a week
  • Do not smoke

When to seek medical attention

There are some cases where it would be best to contact your doctor or call an ambulance after your angioplasty.

Contact your cardiologist if you have any of the following:

  • A lump under the skin around your wound that’s bigger than a pea
  • Redness, swelling and pain around your wound (it might be infected)
  • A fever

Call 999 if you have any of the following::

  • Nonstop bleeding from your wound, even after applying pressure for 10 minutes
  • Severe chest pain that won’t go away, even after taking angina medication
  • The arm or leg where the incision was made is cold, numb or discolored

Your doctor will also inform you of any other warning signs you must look out for after your angioplasty procedure.

FAQs

Is bypass surgery superior to angioplasty?

Coronary artery bypass surgery and coronary angioplasty are different procedures for different situations. Your doctor will make the call on which one is suitable for you based on your overall health, the extent of your coronary artery disease, and whether or not you have other health conditions, such as kidney disease or diabetes.

In bypass surgery, any blocked arteries are bypassed using a healthy blood vessel grafted from your arm, leg or chest, creating a new route for blood to flow to your heart. You may be a candidate for coronary artery bypass surgery if you have three-vessel coronary disease or diabetes, or if your blockage is in the left anterior descending artery (LAD), the most important artery in your body.

Is life normal after angioplasty?

Recovery after angioplasty takes about a week or two. Be sure to follow your doctor’s instructions, take your medication and maintain a healthy lifestyle.

Is angioplasty painful?

In general, angioplasty is not painful. You will probably be awake the whole time. A local anesthetic will be injected at the catheter insertion site. You might feel a pinch from the anesthetic needle. When the catheter is inside your artery, you shouldn’t feel anything, because there the artery has no nerve endings.

You might feel some pressure and discomfort in your chest when the contrast dye is injected or when the catheter balloon is inflated.

What is the difference between angioplasty and heart bypass surgery?

Coronary angioplasty:

  • Local anesthesia (you won’t be asleep during the procedure)
  • Takes 30 minutes to a few hours
  • Minimally invasive, with a catheter inserted at a small incision point, usually near your groin
  • No breathing tube required
  • No machine is required to keep blood and oxygen flow
  • Heart is not stopped during procedure
  • Balloon catheter is inserted into artery to unblock it
  • Discharged the next day
  • Recovery time: 1 to 2 weeks

Heart bypass surgery:

  • General anesthesia (you will be asleep during the procedure)
  • Takes 3 to 6 hours
  • May be more invasive, with a cut down your breastbone to reach your heart, and several cuts for the artery graft, or may be minimally invasive with the use of endoscopic cameras
  • A breathing tube is inserted into your mouth
  • Your heart is temporarily stopped, so a heart-lung machine is required to keep blood and oxygen flowing through your body
  • Blood vessels from other parts of your body are removed and reattached above and below the blocked artery to bypass the blockage
  • Stay in the ICU for one or two days, discharged within a week
  • Recovery time: 6 to 12 weeks
