Overview
Coronary angiography is an X-ray movie of the arteries that supply blood to your heart muscle. A thin, soft tube (catheter) is guided to the heart and a contrast dye is injected to show exactly where and how severe any blockage is.
Dr. Senthilnathan performs most angiograms through the radial artery at the wrist, which means you can sit up and walk soon after the test. If a significant blockage is found, the decision about treatment is discussed with you and your family.
Who may need it
- Heart attack or unstable chest pain
- Abnormal TMT, CT angiogram or echo suggesting blocked arteries
- Before valve procedures or major surgery in high-risk patients
What to expect
- The wrist (or groin) is numbed with local anaesthetic — you stay awake and comfortable.
- A catheter is passed through the artery to the heart under X-ray guidance; you will not feel it moving inside.
- Dye is injected and images recorded. The catheter is removed and a band is placed on the wrist.
Recovery & aftercare
- With wrist access, most patients go home the same day or the next morning.
- Avoid lifting heavy weights with that hand for about 2–3 days. Drink plenty of water to flush out the dye unless told otherwise.
