Coronary Angiography vs Angioplasty Stenting

Updated: Sep 30, 2020

Angiography is the final test to diagnose blood vessel block in heart while Angioplasty is the treatment for this disease via catheter.


What is Coronary Angiography or Angiogram ?


Coronary angiography is a procedure that uses contrast dye to detect blockages in the blood vessels of heart. It is the confirmatory test for diagnosing blood vessel block in heart (coronary artery disease).


What is Coronary Angioplasty or Stenting (PTCA) ?


Angioplasty (PTCA stenting) is a minimally invasive percutaneous procedure performed by Cardiologist to open up blocked coronary arteries and improve blood flow to the heart muscle. It is the treatment of coronary artery disease via catheter. (Unlike bypass surgery, angioplasty does not require incision or opening of the chest). PTCA refers to Percutaneous Transluminal Coronary Angioplasty.

After angioplasty with stenting, blood vessel is increased to its original size with good flow. So patient becomes symptom free and walks home the next day after angioplasty.
