Angioplasty in Iran

Coronary angioplasty treatment in Iran

Coronary angioplasty is a procedure to remove any blocks in blood flow through the artery. When untreated, these blocks can cause heart diseases or heart attack. In angioplasty procedure, the doctor introduces a catheter targeting the block and places a stent or a balloon to clear the narrowing. After heart angioplasty your heart regains the normal blood supply and begins to work efficiently.

Before coronary angioplasty in Iran

Before a scheduled angioplasty, your doctor will review your medical history and do a physical exam. You'll also have an imaging test called a coronary angiogram to see if your blockages can be treated with angioplasty. A coronary angiogram helps doctors determine if the arteries to your heart are narrowed or blocked. Liquid dye is injected into the arteries of your heart through a catheter — a long, thin tube that's fed through an artery from your groin, arm or wrist to arteries in your heart. As the dye fills your arteries, they become visible on X-ray and video, so your doctor can see where your arteries are blocked. If your doctor finds a blockage during your coronary angiogram, it's possible he or she may decide to perform angioplasty and stenting immediately after the angiogram while your heart is still catheterized.

You'll receive instructions about eating or drinking before angioplasty. Typically, you have to stop eating or drinking six to eight hours before the procedure is scheduled. Your preparation may be different if you're already staying at the hospital before your procedure.

Whether the angioplasty is pre-scheduled or done as an emergency, you'll likely have some routine tests first, including a chest X-ray, electrocardiogram and blood tests.

Follow your doctor's instructions about adjusting your current medications before angioplasty. Your doctor may instruct you to stop taking certain medications before angioplasty, such as certain diabetes medications.
Gather all of your medications to take to the hospital with you, including nitroglycerin, if you take it.
Take approved medications with only small sips of water.
Arrange for transportation home. Angioplasty usually requires an overnight hospital stay, and you won't be able to drive yourself home the next day.

During the coronary angioplasty

Your body isn't cut open except for a very small incision in the skin over a blood vessel in the leg, arm or wrist through which a small, thin tube (catheter) is threaded and the procedure performed. Angioplasty can take 30 minutes to several hours, depending on the difficulty and number of blockages and whether any complications arise.

Angioplasty is performed by a heart specialist (cardiologist) and a team of specialized cardiovascular nurses and technicians in a special operating room called a cardiac catheterization laboratory. This room is often called the cath lab.

Angioplasty is commonly performed through an artery in your groin (femoral artery). Less commonly, it may be done using an artery in your arm or wrist area. Before the procedure, the area is prepared with antiseptic solution and a sterile sheet is placed over your body. A local anesthetic is injected to numb the area where the catheter will be inserted. Small electrode pads are placed on your chest to monitor your heart during the procedure.

After numbing the incision area, a small needle is used to access an artery in your leg or arm. A small cut is made in the skin.
Your doctor will insert a thin guidewire followed by a catheter into the artery and thread from the incision area up to the blockage in your heart.
You might feel pressure in the area where the catheter is inserted, but you shouldn't feel sharp pain. Tell your doctor if you do. You also won't feel the catheter in your body.
A small amount of dye is injected through the catheter. This helps your doctor look at the blockage on X-ray images called angiograms.
A small balloon at the end of the catheter is inflated, widening the blocked artery. After the artery is stretched, the balloon is deflated and removed. Your doctor might inflate and deflate the balloon several times before it's removed, stretching the artery a bit more each time.
If you have several blockages, the procedure may be repeated at each blockage. Because the balloon temporarily blocks blood flow to part of your heart, it's common to experience chest pain while it's inflated.

Stent placement:

Most people who have angioplasty also have a stent placed in their blocked artery. The stent is usually inserted in the artery once it is widened by the inflated balloon. The stent supports the walls of your artery to help prevent it from re-narrowing after the angioplasty. The stent looks like a tiny coil of wire mesh.

Here's what happens:

The stent, which is collapsed around a balloon at the tip of the catheter, is guided through the artery to the blockage.
At the blockage, the balloon is inflated and the spring-like stent expands and locks into place inside the artery.
The stent stays in the artery permanently to hold it open and improve blood flow to your heart.
Once the stent is in place, the balloon catheter is removed and more images (angiograms) are taken to see how well blood flows through your newly widened artery.Finally, the guide catheter is removed and the procedure completed.
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 the stent.

iranian surgeryRecovery time after the coronary angioplasty

You'll probably remain hospitalized one day while your heart is monitored and your medications are adjusted. You should be able to return to work or your normal routine the week after angioplasty.

When you return home, drink plenty of fluids to help flush your body of the contrast dye. Avoid strenuous exercise and lifting heavy objects for several days afterward. Ask your doctor or nurse about other restrictions in activity.

Call your doctor's office or hospital staff immediately if:

The site where your catheter was inserted starts bleeding or swelling
You develop pain or discomfort at the site where your catheter was inserted
You have signs of infection, such as redness, swelling, drainage or fever
There's a change in temperature or color of the leg or arm that was used for the procedure
You feel faint or weak
You develop chest pain or shortness of breath
Blood thinners

It's important that you closely follow your doctor's recommendations about your treatment with blood-thinning medications — aspirin and clopidogrel or similar medications.

Most people who have undergone angioplasty with or without stent placement will need to take aspirin for life. Those who have had stent placement will need a blood-thinning medication such as clopidogrel for a year or longer in some cases. If you have any questions or if you need noncardiac surgery, talk to your cardiologist before stopping any of these medications.

10 common question about coronary angioplasty

1Is Coronary Angioplasty Safe?
Coronary angioplasty is a common medical procedure. Although angioplasty is normally safe, there is a small risk of serious complications, such as: Bleeding from the blood vessel where the catheter was placed.
2Who performs coronary angioplasty?
Angioplasty is performed by a heart specialist (cardiologist) and a team of specialized cardiovascular nurses and technicians in a special operating room called a cardiac catheterization laboratory. This room is often called the cath lab.
3What is coronary angioplasty and stenting?
Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to the heart. These blood vessels are called the coronary arteries. A coronary artery stent is a small, metal mesh tube that expands inside a coronary artery. A stent is often placed during or immediately after angioplasty.
4Is angioplasty a major surgery?
Angioplasty opens blocked arteries and restores normal blood flow to your heart muscle. It is not major surgery. ... With coronary angioplasty, a thin, expandable balloon is inserted into the clogged artery and is inflated.
5What should we not do after angioplasty?
Angioplasty does not cure the cause of the blockage in your arteries. Your arteries may become narrow again. Eat a heart-healthy diet, exercise, stop smoking (if you smoke), and reduce stress to help lower your chances of having a blocked artery again. ... They keep your blood from forming clots in your arteries and stent.
6Are you awake during angioplasty?
Angioplasty and stenting procedures are performed in the catheterization lab (or “cath” lab) of a hospital. You will lie on a table and be mildly sedated to help you relax and take away any pain, but you will remain awake throughout the procedure.
7What kind of doctor does angioplasty?
The physician who performs the procedure is called an interventional cardiologist, a heart doctor with additional education, training and experience in treating cardiovascular problems with thin, flexible tubes called catheters.
8How long do stents last in the coronary artery?
More than a year after therapy, it may be a bit higher than with bare metal stents. Even though drug eluting stents have a higher re-obstruction rate, most studies go only four to five years after stenting and indicate that the risk of re-obstruction is generally about 1 to 2 percent for either type of stent.

10At what percent blockage requires a stent?
By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn't need to be stented,” he said.
