What Is Coronary Angiography? How Is It Performed?

Physician Approval: Prof. Dr. Alp Burak Çatakoğlu Last Update: 2026-02-05

What is angiography?

Angiography (Coronary Angiography) is a diagnostic procedure that allows imaging of heart vessels using contrast material. Aim; It clearly shows narrowing, occlusion or structural problems in the vessels.

It is one of the most important steps to make the right treatment decision in case of suspicion of cardiovascular disease. Depending on the angiogram results, drug treatment, stent or different interventional options can be planned.

To whom is angiography performed?

Angiography is most commonly considered in the following situations:

Complaint of chest pain or tightness that increases with exertion,
Suspicion of vascular disease in exercise test/CT angiography,
Evaluation of vascular structure after heart attack,
Detailed vascular analysis before treatment plan in high-risk patients,
Coronary evaluation before some valvular and structural heart procedures.

Types of angiography

In practice, coronary angiography is performed through two main access routes:

Wrist angiography (radial)

is advantageous in terms of comfort and bleeding control in suitable patients. Early mobilization and return to daily life may be faster.

Inguinal angiography (femoral)

It is preferred in some vascular anatomy or technical requirements. The physician decides which method is appropriate according to the patient’s vascular structure.

Preparation before angiography

Preparation before the procedure is important for safety:

Inform your doctor completely about the medications you use,
Kidney function and blood values are evaluated,
Allergy history (especially contrast material) is questioned,
The fasting period before the procedure is arranged according to the planned method,
The entry area (wrist/groin) is prepared for the procedure.

How is angiography performed?

The wrist or groin area is anesthetized with local anesthesia.
A thin catheter is placed into the vein.
The catheter is advanced to the exit of the cardiac vessels.
Contrast material is administered and the veins are visualized.
If there is stenosis or obstruction, a treatment plan is created.

In appropriate cases, stent procedure can also be performed in the same session as angiography.

My personal approach to coronary angiography

Although coronary angiography has been known for years as a troublesome, challenging and risky procedure, most of these difficulties have been eliminated since it was performed from the wrist.

I have been performing angiography procedures from the wrist since 2008. Thanks to this painless procedure performed in approximately 5 minutes with local anesthesia, thousands of my patients have returned home healthy and with good news.

I prefer to use the thinnest and softest catheters in the world. I do the transaction by chatting; If you get excited, I give you short-acting sedative medication.

You can sit and stand up immediately after the procedure. If there is no need to continue with a stent or balloon, discharge is possible after 1-2 hours in most patients.

I aim to secure your heart health with a minimalist, safe and fast approach.

Angiography risks and safety

Angiography is generally a safe procedure. However, as with every invasive procedure, there may be some risks:

Bruising/bleeding at the entry site,
Allergic reaction due to contrast material,
Rare complications such as vascular damage,
Very rare arrhythmia, heart attack or stroke.

Risk level; It varies depending on the patient’s clinical condition, accompanying diseases and vascular anatomy. Complication rates are low in experienced centers.

Things to consider after angiography

The process after angiography is rapid in most patients:

Rest and fluid intake are recommended in the first hours,
The entrance area must be kept clean and dry,
Heavy exertion should be avoided for the first 24-48 hours,
The medications prescribed by your doctor should be used regularly.

When should I see a doctor after angiography?

Contact your healthcare provider without delay in the following cases:

Increasing swelling or active bleeding at the puncture site,
Severe chest pain that does not go away,
Shortness of breath,
High fever,
Feeling faint or marked weakness.

How does angiography price vary?

Angiography price cannot be standardized with a single figure. Price; It varies depending on the clinical condition of the patient, the scope of the procedure, the center infrastructure, the materials used and whether additional intervention such as stent/balloon is required in the same session.

Net pricing should be made after the patient’s medical evaluation and procedure plan. This approach is necessary for both accurate information and safe treatment planning.

How should the doctor and center be chosen for angiography?

A healthier approach than searching for “best” is to choose with measurable criteria:

Interventional cardiology experience and transaction volume,
Technical competence, including wrist approach,
Emergency/complication management infrastructure of the center,
Pre-procedure information and patient communication,
Clarity of post-procedure follow-up plan.

Choosing the right physician-center determines not only the success of the procedure, but also process safety and patient comfort.

The following interventions may be considered according to the post-angiography treatment plan:

Frequently Asked Questions

What is angiography? Angiography is a diagnostic procedure that allows imaging of cardiac vessels with contrast material.

How is angiography done? Vessels are visualized by entering a thin catheter, usually from the wrist or groin.

Wrist angiography or groin angiography is better? In suitable patients, wrist angiography may be advantageous in terms of bleeding and comfort; The decision is made by physician evaluation.

How long does angiography take? Varies depending on the difficulty level of the case; Most diagnostic procedures take a short time.

Is angiography painful? Since it is performed with local anesthesia, most patients do not experience significant pain.

Is angiography risky? Generally safe; Although rare, bleeding, allergy and vascular-related risks may occur.

When will I be discharged after angiography? Discharge is possible on the same day or after a short observation in many patients.

When should I see a doctor after angiography? Active bleeding, increasing swelling, severe chest pain, shortness of breath, or fever require immediate evaluation.

How does angiography price vary? Angiography price; The scope of the procedure varies depending on the material used, center conditions and whether additional intervention is required in the same session.

What should I pay attention to when choosing a doctor and center for angiography? Interventional cardiology experience, center infrastructure, complication management, quality of patient information and follow-up plan should be evaluated together.
