TLDR
Vortex-ring mixing can be quantified using 4D flow and the differences in mixing parameters observed between controls and patients motivate further investigation as indices of diastolic dysfunction and heart failure.Abstract:
To present and validate a new method for 4D flow quantification of vortex-ring mixing during early, rapid filling of the left ventricle (LV) as a potential index of diastolic dysfunction and heart failure.read more
