Loescher, Freundt et al. investigated the contribution of each cytoskeletal filament to passive myocardial stiffness by using a mouse model that allows for specific cleavage of titin; they show that titin is a major cytoskeletal filament controlling myocardial elastic forces, whereas viscous forces are controlled by titin, the microtubules and actin.
