Angiography is derived from the Greek term ‘angeion’ meaning vessel and ‘graphein’ which means to writ. Angiography or arteriography is a technique of medical imaging where an X-Ray is taken of the heart to visualize the inner opening of the arteries, veins and the four heart chambers, right atrium, right ventricle, left atrium and left ventricle. Angiography or angiogram requires the insertion of a catheter, a thin tube into a peripheral artery.
Coronary Angiography or Coronary Catheterization is a minimally invasive procedure to access the coronary flow and blood chambers of the heart using a catheter. Coronary Catheterization was first introduced in 1950s.
