Cine Film Quality of Coronary Angiography
Uninterpretable
The primary endpoint cannot be analyzed secondary to exceedingly poor film exposure or quality (e.g., no images on the film, insufficient contrast injection).
Poor
The primary endpoint can be analyzed with some degree of uncertainty secondary to under- or over-exposure, poor panning, poor engagement, insufficient contrast injection, injection prior to cine-filming, inadequate cine-filming duration, excess collimation, partial obscuration by the diaphragm, and/or omission of images showing major coronary arteries (left or right coronary system).
Average
The primary endpoint can be analyzed. Some images show under- or over-exposure, poor panning, poor engagement, insufficient contrast injection, injection prior to cine-filming, inadequate cine-filming duration, excess collimation, and/or partial obscuration by the diaphragm.
Good
The primary endpoint can be analyzed. Most images show proper exposure, proper panning, proper engagement, sufficient contrast injection, injection after cine-filming, adequate cine-filming duration, minimal collimation, and minimal obscuration by the diaphragm.
Excellent
The primary endpoint can be analyzed. All images show proper exposure, proper panning, proper engagement, sufficient contrast injection, injection after cine-filming, adequate cine-filming duration, minimal collimation, and minimal obscuration by the diaphragm. The culprit lesion is centered in the film during some portion of the cine run to minimize pincushion distortion for quantitative analysis. The culprit lesion is well laid out with no overlap of branches and orthogonal views are obtained to show the culprit lesion in its tightest dimension.
