Why the study?
How does myocardial oxygen metabolism in the right ventricle respond to volume loading and hypoperfusion compared to the left ventricle?

Animal data suggest greater RV O2 extraction reserve than LV; hypothesis-generating, requiring human studies before clinical consideration.
How does myocardial oxygen metabolism in the right ventricle respond to volume loading and hypoperfusion compared to the left ventricle?
The right ventricle has a greater reserve capacity for myocardial oxygen extraction than the left ventricle during volume loading and hypoperfusion.
