Table 3 Difference in left ventricular rotational parameters between participants with aortic stenosis as compared to healthy controls

From: Heart Disease and Left Ventricular Rotation – A Systematic Review and Quantitative Summary

Study Details Matched Controls Apical Rotation Basal Rotation Twist Torsion Twist Rate Peak Untwist Rate Time to Peak Untwist Additional Notes
Popescu et al. 2010 Case–control Level 3 D&B = 19 2D-STE** No Time to peak apical untwisting rate was longer in those with aortic stenosis.
Tzemos et al. 2008 Case–control Level 3 D&B = 19 2D-VVI * Yes         Sample comprised of women.
Stuber et al. 1999 Case–control Level 3 D&B = 17 MRI Tagging No      Time to peak apical untwisting velocity was increased in those with aortic stenosis.
Van Dalen et al. 2011
Case–control
Level 3
D&B = 16
2D-STE***
Yes    
Carasso et al. 2009 Case–control Level 3 D&B = 15 2D-STE* Yes         Aortic stenosis compared to healthy controls.
Nagel et al. 2000 Case–control Level 3 D&B = 15 MRI Tagging No     
Sandstede et al. 2002 Case–control Level 3 D&B = 13 MRI Tagging Yes      
  1. D & B; Downs and Black score, MRI; magnetic resonance imaging, 2D-STE; two dimensional speckle tracking echocardiography, 2D-VVI; two dimensional velocity vector imaging, ***indicates that mitral leaflets and luminal obliteration were used for identifying the basal and apical images respectively, **indicates that mitral leaflets and location inferior to papillary muscle were used for identifying the basal and apical images respectively, * indicates that land marking for short axis images was poorly described, ; significant increase in heart disease group as compared to healthy controls, significant decrease in heart disease group as compared to healthy controls, ; no significant difference between heart disease group as compared to healthy controls.
