Challenges passive LV wall assumption in diastole; leaves open relevance to human filling mechanics.
The study demonstrates that the subepicardium maintains muscle tone during diastole, challenging the assumption that the left ventricular wall behaves as a passive shell during filling.
Stein et al. (1980) studied this question.
