Do you sometimes feel a little pain in your chest, nausea ? Or do you have difficulty breathing when climbing stairs? These can be small signs that the blood vessels (arteries) in our heart are a little blocked. Although many people fear a "heart attack", because of the advancement of medicine today, there are ways to remove such blockages without major surgery. That's why we are talking about such a very important, modern treatment method today.
What is PCI? Simply put...
PCI, which stands for Percutaneous Coronary Intervention , is a relatively simple medical procedure used to remove blockages in the coronary arteries that supply blood to the heart. You may have heard of it as "angioplasty." That's an older name for it.
Imagine if a water pipe in our house gets clogged with dirt, and the water flows very slowly, right? That's how things like fat and cholesterol get deposited in the veins of our heart, obstructing blood flow. In PCI treatment, a very small balloon-like device is inserted into the blocked vein, inflated, and the vein is reopened.
Often, a small mesh tube, called a stent, is permanently placed in the vein to keep it from getting blocked again. Many of the stents used today are a special type that slowly releases a drug to reduce the risk of the vein getting blocked again. These are called drug-eluting stents .
Who really needs this treatment?
If a thick layer of fat and oil builds up inside the blood vessels of your heart, we medically call it atherosclerosis . We call this layer of fat a plaque . This condition restricts the blood supply to your heart. This is when you may experience symptoms like:
- Chest pain or tightness (angina)
- Difficulty breathing
Most importantly, PCI is also performed urgently as a life-saving treatment for someone who has had a heart attack, as it can quickly open the blocked artery and minimize damage to the heart.
How is PCI treatment performed? Let's see step by step
This treatment is performed by an interventional cardiologist. You will be given medication to make you drowsy and calm during this time. So you will not feel any pain, but you will be conscious. Let us explain how this process works.
| Steps | What is happening? |
|---|---|
| 1. Gaining access | The doctor makes a very small hole in your wrist or upper thigh and inserts a small tube (sheath) through it into a blood vessel. |
| 2. Sending the catheter | Through that tube, an even finer tube, called a catheter, is passed to the blocked artery in the heart. |
| 3. Blockage detection | A special type of dye (contrast dye) is injected, and X-ray technology is used to view live images inside the veins. Just like a movie. Then you can see exactly where the block is. |
| 4. Opening the vein | By inflating the small balloon at the tip of the catheter, the trapped fatty layer is pressed against the wall of the vein, opening a path for blood flow. |
| 5. Placing the stent | To prevent the artery from narrowing again, if necessary, a stent is placed in that location. |
| 6. Finishing | The catheter is removed and the insertion site is closed with a compression bandage or small stitches. |
This entire process can usually take between 30 minutes and two hours, depending on the extent of the blockage in your veins.
Can everyone have this treatment?
No. You and your doctor will need to decide together what treatment is best for you. Whether you need PCI, medication alone, or major surgery (Coronary Artery Bypass Graft - CABG) will depend on several factors. For example, the number of blocked arteries, how well your heart is working, and whether you have other medical conditions.
Benefits, risks, and recovery time
Like any medical treatment, this one has benefits and minor risks.
The main advantages are:
- Restoration of blood flow to the heart.
- Symptoms such as chest pain and shortness of breath disappear.
- Less complicated than bypass surgery and shorter recovery time.
Possible risks:
- Bleeding or infection at the catheter insertion site.
- A blood clot forms inside the stent (blood thinners are given to prevent this).
- The same vein becoming blocked again (but this risk is less than 5% due to the drug-eluting stent).
- Very rarely, a stroke occurs.
You can usually resume normal activities within a week after PCI. However, you may need to stop doing things like heavy lifting for a while. The most important thing is to take the blood-thinning medications (e.g., clopidogrel, ticagrelor) that your doctor prescribes for the full duration of the medication, without missing a single day.
Watch out for these symptoms! See a doctor immediately!
If you experience any of the following symptoms after PCI treatment, call your doctor immediately or go to the nearest hospital's Emergency Department (ETU).
- Bleeding, pus-like fluid, or swelling from the catheter insertion site.
- Chest pain (angina) occurs again.
- Fever or chills.
- Numbness or extreme coldness in the arm or leg where the catheter was inserted.
- Dizziness or fainting (syncope) .
- Severe difficulty breathing.
Take-Home Message
- PCI is a modern, safe, and highly effective treatment method used to open blocked blood vessels in the heart.
- This is a great help in saving lives in the event of a sudden heart attack.
- Although recovery after treatment is quick, it is essential to take the medications prescribed by the doctor, especially blood thinners, for the full duration.
- To prevent re-blockage of arteries, it is very important to adopt good lifestyle habits such as quitting smoking, eating a healthy diet, and exercising.
- If you have any questions about your heart health, talk openly with your cardiologist and make the right decisions.
