What is the significance of angiographic stenosis on coronary angiography for treated lesion?
Angiographic stenosis is an important measure of the severity of the coronary artery lesion. It is used to determine the appropriate management of a lesion, for example, whether stenting is warranted or if medical therapy is sufficient. It is usually measured as a percentage of the diameter of the artery, with a higher percentage indicating a more severe blockage. Angiographic stenosis can also be used to assess the success of a treatment, as a decrease in stenosis indicates the treatment was successful in improving the lumen diameter of the artery.
