A recent study from Paldino et al. showed that a genotype-based classification of cardiomyopathies allows an improved long-term arrhythmic outcome stratification compared with a phenotype-based one among patients with genetically determined dilated cardiomyopathy and ARVC phenotypes.82 In their cohort, patients with DSP, LMNA, and FLNC variants experienced consistent VA event rates regardless of the fulfilment of the 2010 TFC or their initial clinical diagnosis. Here, DSP is linked to cardiomyopathy.
