BACKGROUNDDilated cardiomyopathy (DCM) presents a highly heterogeneous spectrum, including a familial subset with elevated arrhythmic risk. Traditional demographic and imaging markers, such as late gadolinium enhancement, have been inadequate for identifying high-risk patients before arrhythmic events. Remodelling of the interventricular septum--central to ventricular mechanics and conduction--may offer improved risk stratification. OBJECTIVESTo identify differences in left ventricular (LV) mor...
