Calculated MRI parameters

VD/AD 2.13 ± 0.37
EFA, % 30 ± 10
C, ml 353 ± 85
Am, ml 81 ± 24
Am/C 0.23 ± 0.02
  • Values are means ± SD; n = 11 subjects. VD, (left + right ventricular volume at diastasis; AD, (left + right) atrial volume at diastasis; EFA, atrial ejection fraction; C, (constant) total volume of the left and right ventricles plus the left and right atrial; Am, (constant) minimal (left + right) atrial volume. Chamber volumes at ventricular end diastole were used to calculate C.
