Fig. 4From: Stent interventions for pulmonary artery stenosis improve bi-ventricular flow efficiency in a swine modelAs expected, quadratic relationships are found between vorticity and energy dissipation rate for both (a). the idealized-theoretical vortex ring and (b). 4D flow CMR measurements of ventricular flow. c Percent energy dissipation from vorticity is compared between groups. *p < 0.05Back to article page
