Regional Helix angle gradient (HAg, °/%) in systole and diastole, mean ± SD

Helix Angle Gradient(°/%)	N = 43	p value
Systolic:		ANOVA: F = 24.0, p < 0.001
Lateral	0.90 ± 0.16	Reference
Anterior	0.98 ± 0.21	p = 0.13
Inferior	0.76 ± 0.15	p < 0.001
Septal	1.0 ± 0.12	P = 0.007
Diastolic:		ANOVA: F = 51.9, p < 0.001
Lateral	0.58 ± 0.13	Reference
Anterior	0.72 ± 0.12	p <0.001
Inferior	0.61 ± 0.13	p =1.0
Septal	0.83 ± 0.14	p <0.001

Values are Bonferroni corrected and therefore a p value of p < 0.05 was taken as the level of significance
