Development of an Ex Vivo, Beating Heart Model for CT Myocardial Perfusion

Table 2

Diameter of stenosis divided by the artery diameter before stenosis, and the area stenosis divided by the area before stenosis, for the FFR-based stenosis grades.

	FFR 0.70	FFR 0.50	FFR 0.30
Mean diameter on CTA	74%	47%	31%
Area stenosis on CTA	49%	22%	12%
