Key result
Dimensional analysis indicates that rather high ventricular pressures are obtained during exercise before the mitral valve closes due to the inertia of mitral blood flow.

May elevate LV pressures before mitral closure in exercise; hypothesis-generating and requires human validation.
Dimensional analysis demonstrates that the inertia of mitral blood flow significantly delays mitral valve closure, resulting in high ventricular pressures prior to closure during exercise.
H. Lauboeck (1980) studied Mitral valve closure delay. Exercise vs. Rest was evaluated on Ventricular pressure before mitral valve closure. Dimensional analysis indicates that rather high ventricular pressures are obtained during exercise before the mitral valve closes due to the inertia of mitral blood flow.
