In the original publication the authors have discovered an error in the software algorithm used to calculate radial contribution to stroke volume (SV). The error consists of a failure to account for the slice gap when calculating septal movement and contribution to SV.

Authors correcting note:

Upon reviewing the algorithm used to calculate septal contribution to stroke volume an error was observed. The error consists of a failure to account for the slice gap when calculating septal movement and contribution to SV, affecting images with a slice gap of > 0 mm. After adjusting the algorithm the following changes are to be made in the manuscript:

  1. 1.

    Septal contribution to SV is -3.5 ml (-5.2–4.1) instead of − 2 ml [− 3.8–2.1].

  2. 2.

    Figure 5 has been revised. See revised Fig. 5 attached.

  3. 3.

    Figure 6 has been revised. See revised Fig. 6 attached.

In conclusion; after correctly taking slice gap into account, there is a minor change in the results as described above. However, the main conclusion of the study holds true.
