In this fascinating Perspective article, the authors propose a novel hypothesis for the developmental origin of the variable phenotypes seen in hypertrophic cardiomyopathy (HCM). They suggest that cross-talk between healthy epicardium-derived cells and abnormally contracting cardiomyocytes could account for the extramyocardial manifestations of HCM, by a putative mechanism of mechanotransduction leading to abnormal gene expression and cell differentiation.
