Coronary angiography

Coronary angiography is useful in evaluating the whole length of the vessel from its origin to its branches. It is useful in identifying any thrombus, stenosis or dissections in coronary vessels. However, accuracy of coronary angiography is limited by subjective interpretation of images[1]. In addition, the site of current stenoses does not predict the site of a subsequent myocardial infarction[2].
