Coronary angiography, also called coronary catheterisation, is an invasive procedure to study the coronary artery anatomy using a special X-ray machine. By getting access to the artery from the groin or wrist, a thin and long catheter can be delivered to the heart to study the heart arteries by injecting iodine based contrast in order to understand the cause of the disease and plan for appropriate treatment.
The Goal of Coronary Angiography
- To obtain heart artery pictures to understand the presence and extent of heart artery blockages.
- To evaluate the most appropriate treatment for the heart artery blockages such as by means of percutaneous coronary intervention (also called coronary angioplasty with balloon or stent) or coronary artery bypass surgery (CABG).
Also known as percutaneous coronary intervention, Coronary Angioplasty is a treatment to unblock the narrowed or blocked artery by means of balloon and/or stent in order to improve the blood flow to the affected heart muscle.
