|Guide for use:|
Stenosis represents the percentage of occlusion, from 0 to 100%, associated with the identified vessel system. Percent stenosis at its maximal point is estimated to be the amount of reduction in the diameter of the 'normal' vessel proximal and distal to the lesion.
In instances where multiple lesions are present in a coronary artery, record the highest percentage stenosis noted.
|Collection methods:||This data is derived from visual recording by the physician reporting the angiogram.|
