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.
