Coronary Angiography (CAG) Treatment in India

starting from

A coronary angiography is a test to find out if you have a blockage in a coronary artery.
Your doctor will be concerned that you’re at risk of a heart attack if you have unstable angina,
a typical chest pain, aortic stenosis, or unexplained heart failure.

During the coronary angiography, a contrast dye will be injected into your arteries through a catheter (thin, plastic tube), while your doctor watches how blood flows through your heart on an X-ray screen.

This test is also known as a cardiac angiogram, catheter arteriography, or cardiac catheterization.

(Note: CAG – Coronary Angiography is a test, not treatment. Not to resemble with CABG – Heart Bypass Surgery)

Angiography is a special diagnostic procedure to visualize the inside of blood vessels. This is usually done by injecting a radio opaque contrast into the blood vessel and using camera (fluoroscope) to take pictures of blood flow . With the help of angiography we can diagnose different conditions of blood vessels like narrowing ,  blockage , inflammation , bleeding etc .

Here we list most frequently asked information about Angiography. In case you have any further questions or would like any other assistance, feel free to write to us.

  • Magnetic Resonance Angiography(MRA) – is a non invasive diagnostic procedure that uses MRI technology to visualize the blood vessels
  • Computed Tomography Angiography(CTA) –also a non invasive diagnostic procedure , useful in cases where many follow up scans are required .
  • Catheter Angiography– its  a minimally invasive procedure , involves introduction of catheter to the problem area to observe the flow of dye through blood vessels and thus identifying  obstructions and narrowing .It is performed for both diagnostic as well as treatment purpose.
  • Coronary Angiography-is a minimally invasive procedure used to study blood vessels supplying the heart, mainly used in patient with heart disease, angina. Also useful in deciding and providing treatment to patient like  Angioplasty .
  • Renal Angiography– used to examine the blood vessels supplying to kidney and to detect any signs of blockage or abnormalities .
  • Pulmonary Angiography– used to examine blood vessels of lungs in cases of pulmonary embolism
  • Cerebral Angiography– used to study the blood vessels in head and neck area .i these blood vessels are narrowed or obstructed it could lead to stroke. Can also be used after stroke to access damage or even to identify brain tumors.
  • Peripheral Angiography-study narrowing of vessels in patients thereby causing reduction in blood flow to legs and feet.
  • Retinal Angiography – to study the abnormalities of blood vessels supplying inside of the eye .
Procedure of Catheter Angiography


Before the Angiography Procedure

The consultant will review your medical history, also try to understand your past and present medical  and surgical condition, whether you are taking any medications especially blood thinners ,check if you are allergic to any medications ,sensitivity to the contrast dye containing iodine.

During the Angiography procedure

This procedure is usually carried out by interventional  radiologist, if angioplasty is also carried out simultaneously then vascular specialist or  cardiologist .

  • You are made to lie flat on your back , blood pressure and heart rate is continuously monitored throughout the procedure.
  • Usually catheter is inserted through the femoral artery in the groin, local anaethesia is given and skin incision made , hollow needle is inserted into the artery
  • After which the catheter i.e a long thin flexible tube  is inserted and manipulated  through the blood stream to the correct artery while viewing continuously through the x- ray imaging device called  fluoroscope
  • When the catheter location is perfect the contrast  agent is injected to make the blood vessels visible and x-rays shots are taken from multiple angles  to view the necessary arteries.
  • These X-ray taken while the dye is flowing through the arteries let the physician study the flow of blood through the blood vessels and help doctor find any blockages .
  • After the x-ray are done the catheter is removed and pressure applied to the puncture site  for 10-15 minutes to reduce chance of bleeding from the artery
  • A bandage is tightly applied and you must stay with back in bed for 6-8 hrs
After the Angiography procedure
  • Patient is monitored in the recovery room, checked for bleeding or chest pain.
  • Advicable to keep the dressing clean and dry to prevent  infection
  • Regularly Check for signs of infection – swelling , redness , discharges
  • Avoid lifting anything heavy for 3-5 days
Diagnosis for performing Angiography
  • Used to detect blood vessel abnormalities
  • Arterial stenosis – narrowing of blood vessel due to atherosclerosis
  • Aneurysm
  • Arteriovenous malformation (AVM)
  • Locating and removing Blood Clots
Factors affecting cost of Angiography

The cost to the patient depends on a variety of factors like

  • The hospital, the patient chooses.
  • Room –Standard single room, deluxe room, super deluxe room for the number of nights specified (including nursing fee, meals, room rate, and room service).
  • Fee for the team of doctors.
  • Medicines.
  • Standard test and diagnostic procedures.

Cost of the follow –up care required after the procedure
