Key result
Acute experimental TR in pigs alters RA mechanics, converting normal pressure-volume loops to single clockwise loops.
Why the study?
How does acute tricuspid regurgitation affect right atrial pressure-volume relationships in a pig model?
How does acute tricuspid regurgitation affect right atrial pressure-volume relationships in a pig model?
Tricuspid regurgitation induces specific, quantifiable changes in right atrial mechanics that can be detected using an impedance catheter.

Alters RA mechanics in acute experimental TR; leaves open translation to chronic human disease or clinical assessment.
Miller et al. (1986) studied Tricuspid regurgitation. Creation of acute experimental tricuspid regurgitation vs. Baseline (before creation of tricuspid regurgitation) was evaluated on Right atrial pressure-volume relationships. Acute experimental tricuspid regurgitation in pigs altered right atrial mechanics, converting the normal figure-of-eight pressure-volume loop to a single clockwise loop in severe cases.
