Coronary Angiography Procedure

Coronary angiography is a diagnostic test used to identify blockages in the blood vessels around the heart, often recommended during a heart attack. Below is a step-by-step outline of the procedure:

1. Preparation:

   • Patient lies down on a table.
   • ECG leads are attached to monitor heart rhythm.

2. Sterilization:

   • The working area (wrist or leg) is cleaned thoroughly to prevent infection.

3. Anesthetization:

   • Local anesthesia is administered to numb the area.

4. Artery Access:

   • A needle is inserted into an artery in the wrist or leg.
   • Pulsatile blood flow is checked to confirm correct needle placement.

5. Guidewire Insertion:

   • A thin guidewire is passed through the needle into the artery.

6. Catheter Insertion:

   • A catheter is maneuvered into position.
   • Contrast dye is injected to visualize blood vessels on an X-ray.

7. Image Capture:

   • Several X-ray images are taken to identify blockages or restricted blood flow.

8. Completion:

   • The catheter is removed.
   • Pressure is applied to the entry point to prevent bleeding.
   • A bandage may be applied.

9. Post-Procedure:

   • If blockages are found, procedures like angioplasty may be recommended.
