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

Table 1

Arterial blood flow (L/min) and blood pressure (mm/Hg) in 5 different stenosis grades.

	Normal perfusion	FFR 0.70	FFR 0.50	FFR 0.30	Total occlusion
Arterial blood flow (SD)	1.0 L/min; (constant)	1.0 L/min; (constant)	1.0 L/min; (constant)	0.93 L/min; (SD 0.05)	0.90 L/min; (constant)
Arterial blood pressure (SD)	82.7 mm/Hg; (SD 0.6)	80.7 mm/Hg; (SD 1.2)	86.7 mm/Hg; (SD 1.2)	88.7 mm/Hg; (SD 1.5)	94 mm/Hg; (SD 2.7)

SD: standard deviation.
