Angiogram (arteriogram) of an adult human heart showing a stenosis (obstruction,arrowed) in the left anterior descending (LAD) coronary artery. The image mas made prior to treating the obstruction by balloon angioplasty (technically called PTCA),in which a plastic balloon is guided into the obstructed artery using digital X-ray imaging & inflated to compress the atheroma plaque & relieve the obstruction. A build-up of atheroma in a coronary artery (coronary artery disease) gives rise to the symptoms of chest pain called angina pectoris & may progress to complete obstruction and cause a heart attack | |
