May indicate CS pressure as extravascular compression in dogs; hypothesis-generating for human coronary pressure-flow relations.
Does coronary sinus occlusion affect coronary pressure-flow relations in anesthetized open-chest dogs?
Coronary sinus pressure acts as an extravascular compression rather than a perfusion pressure, directly affecting the zero-flow pressure intercept in the coronary circulation.
Osamu Nishiyama (1984) studied this question.
