I suppose you are asking about the diagnostic conventional angiography
done in cath labs across hospitals all over the world.
The approximate charges for an angiography could be around 20000 INR (Rupees twenty thousands). However if there is any problem in heart detected during angiography then cardiologist may like to do other procedures like balloon angioplasty
placement. For these additional procedures done together with angiography, the charges can go up by many thousands of rupees.
The best approach would be to have a discussion with your cardiologist regarding the total cost and risks involved.
