Key result
Acute pericardial tamponade shifted the LV and RV intracavitary diastolic P-V relation by increasing pericardial pressure, but caused no change in the transmural P-V relationship.
Why the study?
Does acute pericardial tamponade alter left and right ventricular transmural pressure-volume relations in an animal model?
Does acute pericardial tamponade alter left and right ventricular transmural pressure-volume relations in an animal model?
Acute pericardial tamponade alters intracavitary pressure-volume relations solely through increased pericardial pressure, without changing intrinsic myocardial compliance.

Tamponade shifts intracavitary but not transmural diastolic P-V relations via pericardial pressure alone; leaves open translation to human ventricular mechanics.
Smiseth et al. (1991) studied Acute pericardial tamponade (n=11). Acute pericardial tamponade (incremental pericardial infusion) vs. Baseline was evaluated on Left and right ventricular intracavitary and transmural pressure-volume relations. Acute pericardial tamponade shifted the LV and RV intracavitary diastolic P-V relation by increasing pericardial pressure, but caused no change in the transmural P-V relationship.
