What is coronary revascularization, and which procedures does it include?
Coronary revascularization is the general name for any treatment that restores blood flow to heart muscle when the coronary arteries are narrowed or blocked by plaque. It is not a single operation. It covers percutaneous coronary intervention (balloon angioplasty with a stent, done through a catheter) and coronary artery bypass grafting (CABG, open-heart surgery in which a vein or artery graft is sewn around the blockage). Sometimes both are used in different vessels. Hospitals in Turkey offer both routes, usually in the same cardiology and cardiac surgery centre, which makes the comparison easier to do on one site.
This guide explains how coronary revascularization works, how a heart team chooses between the routes, what the evidence says, what it costs compared with the UK, US and Germany, and what recovery involves. It is general information and does not replace the advice of your cardiologist. Related guides cover coronary stenting and the wider field of cardiology treatments in Turkey.
When is revascularization needed, and when are medicines enough?
Revascularization has two main purposes: to treat an acute heart attack by reopening the culprit artery, and to relieve symptoms or protect the heart in people with long-standing coronary disease. For stable angina, trials such as COURAGE and ISCHEMIA found that adding a procedure to good medical therapy did not clearly reduce deaths or heart attacks overall, although it helped chest pain. The picture is different for people with left main disease, three-vessel disease with reduced pumping function, or diabetes with multivessel disease, where surgery has shown a survival advantage in some trials such as FREEDOM and SYNTAX. Guidance from the European Society of Cardiology and the American Heart Association reflects these distinctions.
The practical lesson is that your anatomy and symptoms, not the treatment on offer, should decide the route. A trustworthy clinic will ask for your angiogram and may tell you that no procedure is needed yet.
Stenting or bypass surgery: how do the two routes compare?
The table sets out typical differences. Your own heart team will adjust them for your arteries, your diabetes status, the strength of your heart and other illnesses.
| Route | Best suited to | Typical limits |
|---|---|---|
| Stent (angioplasty) | One or two vessels, simple lesions, heart attack, frailty | Artery can re-narrow; months of antiplatelet tablets; less durable in complex disease |
| Bypass surgery (CABG) | Left main or three-vessel disease, diabetes, reduced pumping strength | Chest incision; two to three months recovery; anaesthetic and wound risks |
| Hybrid approach | Selected cases combining one graft with a stent | Needs a centre with both teams; limited evidence |
For the surgical option read our guide to coronary bypass surgery; for the catheter route see coronary angioplasty.
How is the decision made? The role of the angiogram and the heart team
Everything starts with a picture of the arteries. A coronary angiogram (a catheter test with contrast dye) or a CT coronary angiogram shows where narrowings lie and how severe they are. Sometimes a pressure-wire test (fractional flow reserve) or ultrasound inside the artery measures whether a narrowing actually limits blood flow. The SYNTAX score, which grades how complex the disease is, helps heart teams choose between stents and surgery. Ask your clinic to review your existing angiogram before you travel, so you know whether a repeat test is needed; see CT coronary angiography for how the non-invasive test works.
Coronary revascularization cost in Turkey compared with the UK, US and Germany
Prices below are approximate ranges to show scale, not hospital quotes. The two routes differ substantially, so the table separates them.
| Country | Stent (angioplasty), approximate | Bypass surgery (CABG), approximate |
|---|---|---|
| Turkey | €3,500 – €8,000 | €10,000 – €22,000 |
| United Kingdom | €9,000 – €18,000 | €22,000 – €40,000 |
| United States | €20,000 – €45,000 | €60,000 – €130,000 |
| Germany | €8,000 – €15,000 | €20,000 – €35,000 |
What changes the price: the number of stents or grafts, whether the surgeon uses a radial or mammary artery, heart-lung machine or off-pump technique, days in intensive care and on the ward, and any complications. Packages normally include pre-operative tests, the procedure, hospital nights, medication on discharge and transfers; ask for the list in writing, with the number of stents or grafts assumed.
What happens during a stent procedure and during bypass surgery?
A stent procedure takes 30 to 90 minutes under sedation through the wrist or groin: the cardiologist inflates a balloon at the narrowing and leaves a drug-eluting stent in place. Bypass surgery takes three to five hours under general anaesthesia. The surgeon divides the breastbone, takes a graft (commonly the internal mammary artery from the chest wall and a vein from the leg or an artery from the arm), and sews it from the aorta to beyond the blockage. Most operations use a heart-lung machine; some are done on the beating heart. You wake in intensive care with drains and a breathing tube that is removed within hours.
Who is a good candidate, and who is not?
Revascularization is advised when symptoms are not controlled by medicines, when tests show a large area of heart muscle short of blood, or after a heart attack. Poor candidates include people with narrowings that do not limit blood flow, those whose symptoms come from another cause, and people too unwell for surgery who may do better with a stent or tablets. Unstable chest pain, breathlessness at rest or a recent heart attack are reasons to go to the nearest hospital and not to arrange travel.
How long is the stay in Turkey, and what does recovery look like?
After a stent most people stay one night and remain near the clinic for two to four days before flying. After bypass surgery expect five to seven nights in hospital, then a further week or so nearby, because the surgeon needs to see your wound, your blood tests and your walking before you travel; flying is usually possible after about two weeks if you are stable.
- Stent: walking the same day, desk work after about a week, cardiac rehabilitation over several weeks.
- Bypass: walking on day one or two, no lifting for six to eight weeks while the breastbone heals, driving only after your surgeon agrees, and full recovery over two to three months.
- Both: antiplatelet or other tablets as prescribed, written discharge summary, and an appointment with your own cardiologist at home.
What are the risks of coronary revascularization?
Stents carry risks of bleeding, contrast reactions, kidney strain, artery injury, clot formation inside the stent and, rarely, heart attack or stroke. Bypass surgery carries the risks of major surgery: wound infection, bleeding, irregular heart rhythm (atrial fibrillation) after the operation, kidney problems, temporary confusion and, uncommonly, stroke, heart attack or death. The NHS and the British Heart Foundation explain that risk is higher in emergencies, in older age and in people with kidney disease, diabetes or weak heart function. Your surgeon should give you an estimate based on your own history before consent, ideally using a recognised scoring system such as EuroSCORE II.
Will revascularization stop my heart disease coming back?
No. Both routes treat blockages and not the cause. Grafts and stents can narrow over time unless you stop smoking, control blood pressure, cholesterol and blood sugar, exercise and take your medicines. Arterial grafts last longer than vein grafts, and modern drug-eluting stents re-narrow much less often than early designs, but long-term protection depends on lifestyle and drugs. Ask the clinic what follow-up and rehabilitation advice you receive for use at home.
How to choose a hospital, and red flags
Choose a licensed hospital with a catheterisation laboratory, cardiac surgery, intensive care and 24-hour cardiology cover on one site, so that a complication can be managed without transfer. Look for a heart-team discussion before the plan is agreed. Red flags include a recommendation made without seeing your angiogram, promises of a permanent cure, quotes with no stent or graft number, and pressure to pay a deposit quickly.

Frequently asked questions
It is any procedure that restores blood flow to the heart muscle through narrowed or blocked coronary arteries, either by balloon angioplasty with a stent or by coronary artery bypass surgery, and sometimes by combining both.
It reopens blood flow reliably and is life-saving in a heart attack. In stable disease it mainly relieves chest pain, although bypass surgery has shown a survival benefit in left main, multivessel and diabetic disease in some trials.
Approximate ranges are €3,500 to €8,000 for a stent and €10,000 to €22,000 for bypass surgery in Turkey, compared with about €22,000 to €40,000 for bypass in the UK. The price depends on the number of stents or grafts.
It depends on your arteries, diabetes and heart strength. Stents suit one or two simple narrowings; bypass is often advised for left main or three-vessel disease. A heart team should decide after seeing your angiogram.
After a stent most people return to desk work within about a week. After bypass surgery expect two to three months for full recovery, with no heavy lifting for six to eight weeks while the breastbone heals.
Allow two to four days for a stent and around two weeks for bypass surgery, including five to seven hospital nights. The team needs to check your wound, blood tests and walking before you fly.
A stent is done under sedation with brief chest pressure during balloon inflation. Bypass surgery is done under general anaesthesia; soreness in the chest and leg wound is controlled with painkillers and eases over weeks.
Risks include bleeding, infection, kidney strain, irregular heart rhythm and, rarely, heart attack, stroke or death. Risk is higher in emergencies and in people with diabetes, kidney disease or weak heart function.
Usually yes once you are stable and the surgeon or cardiologist agrees: after a few days for a stent, and often around two weeks after bypass surgery. Confirm with your doctor and travel insurer.
Yes. Stents require antiplatelet tablets for months, and both routes usually need a statin, blood pressure medicines and sometimes aspirin long term. You receive a written discharge list to give your own doctor.
