Key result
Dilated cardiomyopathy is associated with altered left ventricular blood flow, demonstrating a significantly lower direct flow to end-diastolic volume ratio (20% vs 35%) compared to healthy subjects.
Why the study?
Does 4D left ventricular blood flow organization differ between normal and failing hearts?
Cross-Sectional (n=13)
Does 4D left ventricular blood flow organization differ between normal and failing hearts?
Absolute Event Rate: 20% vs 35%
p-value: p=<0.001
4D flow MRI demonstrates that normal LV blood flow organization is significantly altered in dilated cardiomyopathy, characterized by decreased direct flow and increased delayed ejection flow.
Altered LV flow patterns in DCM support further 4D flow research; leaves open prognostic or therapeutic utility.
To measure the volume and distribution of separate flow components in normal and dysfunctional left ventricles (LV).

Carlhäll et al. (2010) conducted a cross-sectional in Dilated cardiomyopathy (n=13). Dilated cardiomyopathy vs. Healthy subjects was evaluated on Direct flow to end-diastolic volume (EDV) ratio (p=<0.001). Dilated cardiomyopathy is associated with altered left ventricular blood flow, demonstrating a significantly lower direct flow to end-diastolic volume ratio (20% vs 35%) compared to healthy subjects.
