Electromechanical Profiling in Genotyped Dilated Cardiomyopathy with Left Bundle Branch Block.
Genetic testing combined with heart imaging reveals how electrical and mechanical dysfunction patterns differ across rare cardiomyopathies.
Multicenter electromechanical profiling of genotyped dilated cardiomyopathy patients with left bundle branch block identified genotype-specific patterns of mechanical dyssynchrony and electrical activation that differ significantly between genetic subgroups. These findings suggest that genotype-informed electromechanical characterization could help guide CRT patient selection and programming in rare genetic DCM, potentially improving outcomes in a population with high mortality and limited individualized management data.

Why it surfaced
Addresses personalization gap in rare genetic DCM management where CRT outcomes are variable; genotype-specific electromechanical profiling provides a potential path to individualized CRT decisions in a high-mortality rare disease subgroup.
