Comments on Defining the Contribution of Diastolic Vortex Ring to Left Ventricular Filling
[...]according to the fluid dynamics conservation laws, the role of the LV vortex in diastolic filling volume cannot be evaluated merely by volumetric balances, but needs to be considered in conjunction with the corresponding momentum balances and intraventricular pressure gradients. The analysis di...

The analysis did not take into consideration that every gradient field is a conservative field by definition; hence, it has no rotational component. [...]the pressure decomposition presented in their analysis is rather improper for fluid dynamics, and we do not believe that it should be used for such a purpose. |
