Why the study?

Small effusions were associated with reduced DEVM; hypothesis-generating for altered compliance, requiring prospective confirmation before clinical consideration.
Does the presence of a small pericardial effusion affect left ventricular relaxation as measured by echocardiography?
Small pericardial effusions are associated with impaired left ventricular relaxation (decreased DEVM), suggesting altered pericardial compliance even without other changes in left ventricular function.
Firestein et al. (1980) studied this question.
