In the version of the article originally published online, there was an error in Fig. 1a. In the 3× 3 panel, the images indicated as ‘CMR cine of four-chamber view’, ‘Parametric image of k2’ and ‘Polar map of k2’ were incorrectly matched to the rows indicated as Control, MYBPC3 carrier and MYH7 carrier. The image should have shown the lowest O2 consumption (most purple) images for Control and highest O2 consumption (most orange) for MYH7 carriers. The corrected figure is given below.
